Arc’teryx Serratus Hoody: First look at the new technical softshell

Last updated: January 23, 2025 by Brent Boyer

The front and back of the Arc'teryx Serratus Hoody for men

The Serratus Hoody, and its women's counterpart, feature two different softshell fabrics to maximize durability and breathability.

Never a company to rest on its laurels, Arc'teryx's midwinter release of the Serratus Hoody adds a new technical softshell to the brand's ever-expanding jacket lineup. The Serratus Hoody, available in both men's and women's versions (the women's is called the Psiphon Hoody), was designed with climbers in mind but is an intriguing choice for anyone who loves a good softshell for its stretch, warmth, and versatility.

In this article we take a first look at the new Serratus Hoody and Psiphon Hoody, including materials, weather resistance, fit, feel and features. We'll also see how they stack up to other softshells from Arc'teryx, including the legendary Gamma line.

BTW, one of our favorite ways to sort through Arc'teryx's impressive number of jackets is with their handy jacket finder tool.

Fun fact: The men's version was named for Serratus Mountain, a 7,632-foot peak in British Columbia's Coast Mountains. The serratus anterior is also a muscle that attaches the shoulder blade to the ribs and is considered essential for climbing. The Psiphon name reboots Arc'teryx's former Psiphon line of softshell jackets.

Softshell vs Hardshell Jackets

Feel free to skip ahead if you're already well versed in the distinctions between softshell and hardshell jackets. But it's worth a brief overview for those of you less familiar.

Softshells

Purpose: Made for comfort and breathability during high-output activities like hiking, trail running, climbing or even skiing in milder, drier conditions. Best for when you need moderate weather resistance with maximum flexibility.
Fabric: Constructed from stretchy, water-resistant (not waterproof) fabrics like woven polyester or nylon, often treated with a DWR (durable water-repellent) coating to help shed light amounts of precipitation.
Features: Prioritize mobility and comfort, often with a fleece-lined interior for added warmth.
Breathability: Highly breathable, making them great for sweat-inducing activities.
Feel: Softer, more flexible, and quieter than hardshells, offering better freedom of movement.

Hardshells

Purpose: Designed for maximum protection in harsh weather conditions like heavy rain, snow, or strong winds. Ideal for activities like alpine climbing, skiing, or backpacking in unpredictable climates.
Fabric: Made with fully waterproof and windproof materials, typically featuring membranes like Gore-Tex. They are often 3-layer or 2.5-layer constructions, prioritizing weather resistance.
Features: Lightweight and packable, often with taped seams, adjustable hoods, and water-resistant zippers.
Breathability: Less breathable than softshells but better at keeping you completely dry.
Feel: Stiffer and less stretchy, with a "crinkly" texture, focusing on durability and protection.

So, whether you need a hardshell or a softshell really depends on the day and the activity. I live at 9,000 feet in the heart of the Colorado Rockies and for years have snowboarded on bluebird days in a fleece-lined Marmot softshell. Of course, I also have several technical hardshells for when I'm skiing and riding in all other conditions (my current go-tos are the Arc'teryx Sabre SV for when it's nasty outside and the Stio Environ Jacket for most other days).

Materials & Construction

Back to the Serratus and Psiphon hoodies. True to their Arc'teryx softshell status, both are constructed with a mix of Fortius DW 2.0™ and Aequora AirPerm™ fabrics.

Fortius DW 2.0™ is a durable, high-stretch and breathable recycled nylon fabric also used by Arc'teryx in its popular Gamma softshell jackets. But whereas the Gamma line uses Fortius DW 2.0™ throughout, the Serratus and Psiphon jackets substitute a lighter-weight and even more breathable fabric under the arms and across the back. This stretchy recycled nylon fabric, called Aequora AirPerm, will give the Serratus Hoody and Psiphon Hoody an unmistakably lighter and closer-to-body feel than the Gammas. To point, the men's Serratus Hoody is 35% lighter than the men's Gamma MX Hoody.

Here's how Arc'teryx compares the Serratus Hoody to the Gamma MX Hoody for men: https://arcteryx.com/us/en/compare/X000009570/X000008485
Here's how Arc'teryx compares the Psiphon Hoody to the Gamma MX Hoody for women: https://arcteryx.com/us/en/compare/X000009515/X000009456

The back of the new Arc'teryx Serratus Hoody

That gray expanse across the back and under the arms is the lighter-weight, more breathable Aequora AirPerm fabric.

The mixed construction makes sense given Arc'teryx's positioning of the Serratus and Psiphon jackets as technical climbing shells. The durable Fortius DW 2.0 fabric across the front body, sleeves and shoulders provides needed protection when rubbing up against rock, while the Aequora AirPerm increases the ventilation everywhere else.

We'll point out here that Arc'teryx says it body mapped the dual-fabric construction of both hoodies in a gender-specific way. From Arc'teryx.com:

“Based on thermal mapping data from our Advanced Concepts team we know that women and men heat-up and cool-down at different rates during outdoor activities, which is why we strategically placed breathable materials on our women’s Psiphon kit in high humidity areas, and added warmth where we know she’ll need it most.”

— Ashley Anson, vice president of product design, women’s apparel, snow apparel and hardgoods and accessories

A side-by-side comparison of the Serratus Hoody and Psiphon Hoody show the nuanced placement differences of the Aequora AirPerm panels. The men's version features AirPerm panels all the way down the underarms to the wrist and a straight back panel stretching across the middle of the shoulder blades down to the lower back. The back panel on the women's version comes up higher on the back, while the underarm AirPerm panels end above the elbow, not the wrist.

Back and underarm panels comparison of Arc'teryx Serratus Hoody for men and Arc'teryx Psiphon Hoody for women

For those of you who aren't climbers but still appreciate a great softshell, these two new jackets absolutely merit consideration for other high-output activities. We see the Serratus Hoody as a great hiking, trail running, ski touring and cross-country skiing option across all four seasons, including here in Colorado. The expanse of Aequora AirPerm fabric across the center of the back will feel particularly well suited to wearing a pack.

Arc'teryx also says the Serratus and Psiphon jackets and pants are designed with cut-and-sew construction in high-wear areas for easy repair in the field.

Weather resistance

As mentioned before, a softshell is almost never waterproof or windproof. And that's true of the Serratus Hoody. Instead, it's water-resistant, which Arc'teryx describes as "able to resist the penetration of water to some degree but not entirely." As for wind, the plain weave nylon of the Fortius 2.0 is dense enough to be wind resistant, but nothing more.

The Serratus Hoody and the Psiphon Hoody are treated with FC0 DWR, a PFAS-free durable water repellant finish that will help them shed light amounts of precipitation. A DWR finish won't make your softshell waterproof, but it will help keep you dry in a brief rain or light snow shower. If there's a chance you'll encounter heavy rain or snow, be sure to have a waterproof hardshell with you as well.

The magical (actually, scientific) ability of a DWR finish to cause water to bead up and roll off fabrics.

Warmth & Insulation

Softshells like the Serratus Hoody and Psiphon Hoody aren't insulated in the traditional sense; you won't find any CoreLoft or PrimaLoft synthetic lining to add warmth. But the Fortius DW 2.0 fabric offers excellent warmth-to-weight ratio, as anyone who has worn a Gamma MX jacket or hoody can attest. When combined with appropriate baselayers, the Serratus Hoody should keep you warm in temperatures as low as freezing, particularly when you're working hard.

Fit & Feel

Arc'teryx says it designed the Serratus Hoody and Psiphon Hoody with multi-pitch alpine climbs in mind. As such, the focus on articulation emphasizes both freedom of movement as well as gender-specific design. How does that translate to the actual softshells?

Well, the four-way stretch properties of both the Fortius DW 2.0™ and the Aequous AirPerm ™ mean the Serratus and Psiphon move with your body and feel way less restrictive than other jackets, particularly hardshells. The sleeves of the Serratus and Psiphon hoodies are also cut longer than other jackets, which climbers will appreciate when they're reaching for that next hold.

When it comes to feel, a primary reason for the popularity of softshells in general is that they're just more comfortable to wear. That stretchy, breathable fabric not only feels good it also lacks the crinkly nature of most weatherproof hardshells.

Additional Features

Pockets

You'll find only two pockets on the Serratus Hoody (and the women's Psiphon Hoody): external, zippered handpockets that are harness and backpack friendly. There are no internal pockets. But the placement of the pockets is different between the Serratus and Psiphon. The Serratus Hoody's pockets are larger and positioned on the edges of the torso, with the interior of the pockets stretching toward the jacket's main zipper. The Psiphon Hoody's pockets are smaller and higher up on the chest, extending out from the main zipper toward the armpits. See the pics below.

Hood

The Serratus and Psiphon have helmet-compatible StormHoods with an adjustment cord at the back of the hood and two pull adjustments on either side of the collar. We're big fans of Arc'teryx's StormHood - the fit, visor and adjustability means it fits well and doesn't restrict your vision whether or not you're wearing a helmet.

Zippers

The big callout here is a two-way front zipper for when you're on belay - but only on the men's Serratus Hoody. For some reason Arc'teryx chose not to include a two-way zipper on the women's Psiphon Hoody. The main zipper and pocket zippers on both models have low-profile rubber pulls for easy up and down, with or without gloves.

Two-way main zipper on the Arc'teryx Serratus Hoody

Sorry, ladies. Only the Serratus Hoody gets a two-way main zipper.

Cuffs

Both sleeves on the Serratus Hoody feature adjustable hook-and-loop cuffs. It's a different story for the women with the Psiphon Hoody, however, which instead has shaped cuffs with elastic on the inner half to seal out drafts.

The men's Serratus Hoody features hook-and-loop adjustable cuffs.

Shaped, elastic cuffs on the women's Arc'teryx Psiphon Hoody

Our take

Arc'teryx and other leading technical outdoor brands have no shortage of options when it comes to breathable jackets for high-output activities. The Proton and Atom lines (read our comparison ofd the two here), for example, are perennial favorites. But the true softshell category is a bit smaller, and the main competitor within the Arc'teryx line is the Gamma, which is a heavier and warmer jacket than both the Serratus Hoody and Psiphon Hoody.

Although positioned as a jacket for climbers, we think the Serratus (and the Psiphon) is a worthy option for anyone who likes the idea of a stretchy softshell that's super breathable for activities like running, hiking and ski touring. We'll update this article once we've had sufficient time to truly put the Serratus Hoody to the test.

Arc’teryx Cerium vs Cerium SV jacket comparison| How to choose

Last updated: December 9, 2024 by Brent Boyer

The Cerium Hoody in Rune (left) and the Cerium SV Hoody in Black Sapphire (right) may come from the same product collection, but they're distinct jackets in almost every way.

Arc’teryx’s Cerium line of jackets and vests falls squarely in the lightweight to ultralightweight down category. These are technical garments made to be packable and worn as insulating midlayers for adventures in cold weather, or as an outer layer when it’s chilly but not freezing. The Cerium SV (SV stands for "Severe Weather" in Arc’teryx’s product lexicon) takes it one step further, offering substantially more warmth than its regular Cerium sibling. But unlike with the Cerium Jacket and Cerium Hoody, you won’t be squeezing the ultra-puffy Cerium SV under a shell. This cloud-like jacket is a standalone layer for frigid days.

So which Cerium is right for you? Let’s take a closer look.

But first, here’s how Arc’teryx compares the Cerium vs Cerium SV: https://arcteryx.com/us/en/compare/X000007313/X000008429

Winter 2024-2025 Cerium lineup

Insulation comparison: Cerium vs Cerium SV

Arc'teryx Cerium and Cerium SV down jackets

The wider baffles of the Cerium SV Hoody, at right, provide more room for that super-lofty 1000 fill-power European grey goose down. The Cerium Hoody, left, uses 850 fill-power European white goose down.

There’s one overriding reason the Cerium and Cerium SV are able to provide so much warmth with such little weight: goose down. Goose down is the gold standard when it comes to exceptional warmth-to-weight ratios in jackets. The quality of down is typically measured by its fill power, but fill weight is also important when determining the relative warmth of a down garment.

The Arc’teryx Cerium Hoody, Jacket and Vest - in both men’s and women’s versions - use 850 fill-power European white goose down. And like all down sourced by Arc’teryx, it’s certified to the Responsible Down Standard (RDS). Most premium outdoor brands, Arc’teryx among them, use down with fill powers ranging from 700 to 1000, but the sweet spot is typically 700 to 850. The higher the fill power, the more loft the down has (think fluffiness). Loft is a good thing, because down’s incredible insulating power comes not from the down itself, but from all the air pockets created within that fluffy down. Our body heat warms the air in those pockets, which in turn insulates us.

If you want to better understand the working principles of down and synthetic insulation, read our extensive Temperature Ratings of Jackets article.

Higher fill-power down is not only a better insulator (i.e., warmer), it’s also more expensive, which is one reason you rarely find 1000 fill-power down in jackets. With its 1000 fill-power European grey goose down, the Cerium SV is not only $200 more expensive than the Cerium, it’s also noticeably warmer.

Stay with us here: That additional warmth provided by the Cerium SV over its Cerium counterparts isn’t solely the result of fill power. Fill weight, a measure of how much down is in a jacket, also plays a significant role. If two jackets have the same fill power down, but one has double the amount (fill weight) of t+hat down, it’s absolutely going to be warmer. In the case of the Cerium and Cerium SV, not only does the SV model have a higher fill power down, it also has more down by weight within it.

	MSRP	Down fill power	Down fill weight	Jacket weight
Cerium Hoody	$400	850	114g	11.9oz
Cerium SV Hoody	$600	1000	130g	15.4oz
Thorium Hoody	$500	750	148g	1lb, 2.2oz
Thorium SV Hoody	$600	750	169g	1lb, 8.5oz

Edit Table

One more thing to know about the insulation in both the Cerium and Cerium SV jackets: Because down insulation is relatively worthless when wet (no air pockets = no warmth), Arc’teryx supplements with synthetic insulation in specific areas of the jackets prone to moisture, whether from the user (perspiration) or nature (precipitation).

The Cerium includes Coreloft 80 and Coreloft 100. The Cerium SV uses PrimaLoft Silver 80 and PrimaLoft Silver 140. Both models deploy the synthetic insulation in the same areas: the armpits, the top of the shoulders, and where the jacket meets your chin/mouth when fully zipped. Arc’teryx calls this Down Composite Mapping.

Note the shoulder panels of the Cerium Hoody, where Coreloft synthetic insulation is used instead of the clearly visible down in other areas.

Cerium SV Hoody PrimaLoft Silver synthetic insulation under the armpits

The same goes for the Cerium SV Hoody, in this case the armpit panel with its PrimaLoft Silver synthetic insulation.

Materials & Durability: Cerium vs Cerium SV

The fill power and fill weight of their down insulation isn’t the only difference between the Cerium and Cerium SV. The Cerium uses an Arato 15-denier nylon for its face fabric, compared to the 20-denier Pertex Diamond Fuse face fabric of the Cerium SV. The Pertex fabric, which is new to the Cerium SV, claims to be both ripstop and downproof. Importantly, Pertex says its Diamond Fuse technology offers twice the abrasion resistance of traditional nylon filaments in addition to improved water shedding.

Arc’teryx’s fabric choices for the Cerium and Cerium SV further underscore the unique use cases of each jacket. Though we’ve yet to experience any issues with the durability of our Cerium Hoody, its thinner 15d fabric is better suited to life as a midlayer. The Cerium SV, on the other hand, uses a stronger, more durable 20d ripstop nylon to better withstand the rigors of life as an outer layer.

Would we want to expose either the Cerium or Cerium SV to bushwacking through dense foliage or other high-abrasion activities? Probably not. Though we wouldn’t describe either jacket as fragile, these are ultralight technical down garments, and their face fabrics are intentionally lighter weight than those in more robust, everyday down jackets like the Thorium and Thorium SV. However, Arc’teryx says the Pertex Diamond Fuse is stronger than the 30d Arato of the Thorium and Thorium SV; we haven’t been able to test that claim.

On the inside of all models of Cerium and Cerium SV is a downproof 20-denier nylon. Downproof simply means you won’t find the prickly ends of down feathers working their way out of your nice Arc’teryx jacket.

	Face fabric	Liner
Cerium Hoody	15d Arato nylon	20d Arato nylon
Cerium SV Hoody	20d Pertex Diamond Fuse nylon	20d Arato nylon
Thorium Hoody	30d Arato nylon	20d Arato nylon
Thorium SV Hoody	30d Arato nylon	20d Arato nylon

Weatherproofing: Cerium vs Cerium SV

Because down is mostly worthless when wet, and because neither the Cerium nor the Cerium SV offer Gore-Tex waterproofing, these jackets are best for cold, dry conditions. That said, both lines have a PFAS-free Durable Water Repellent (DWR) coating on their face fabrics, which means they’ll be effective at shedding light rain or snow for short periods of time. Sustained precipitation will eventually soak through their face fabrics, so if there’s a chance you could encounter rain or snow, either bring a shell that can be worn over the Cerium and Cerium SV (a tougher task given the SV’s bulk), or choose a different jacket for the occasion.

The Cerium SV also stands out for its windproof outer, another factor in it earning Arc’teryx’s “Severe Weather” distinction. The standard Cerium line of jackets, hoodies and vests are wind resistant, by contrast.

Cerium SV Hoody face fabric treated with Durable Water Repellant

The Cerium SV Hoody isn't waterproof, but its face fabric is treated with a PFAS-free Durable Water Repellent (DWR) to help shed light to moderate precipitation for short durations.

If you want the warmth of down insulation but the weather protection of Gore-Tex, consider the Beta Down Insulated Jacket for all-around winter conditions, or the Fissile SV Down Jacket for ski-specific use. Both are fully waterproof and windproof.

Fit & Feel: Cerium vs Cerium SV

The Cerium Hoody and Cerium Jacket are cut with a trim fit, again befitting their status as midlayers first and outer layers second. I’m 5-foot-9 and 175 pounds, and the Cerium Hoody in size medium fits me well, albeit with limited room underneath for bulky midlayers. Conversely, that trim fit means the Cerium fits very nicely under most shells, including my Beta SL and Sabre SV.

The Cerium SV, on the other hand, features a regular fit. It is, after all, an outer layer for frigid weather. I have plenty of room for a baselayer and midlayer underneath my size medium Cerium SV.

It’s worth pointing out that these jackets look and feel totally different. The trim-fit Cerium Hoody is certainly comfortable, but it’s not what I’d reach for as a standalone jacket when temperatures dip below freezing. As a point of style, some of you may not like the mottled look of the Cerium line, especially in some of the lighter color fabrics. That 15d Arato nylon is fairly translucent, and the color variations from the goose down insulation is often visible through the fabric. To wit, that’s why Arc’teryx used white goose down instead of grey goose down in the Cerium.

The Cerium SV has wider baffles to give space to that lofty 1000 fill-power down, and its 20d Pertex nylon fabric is noticeably shinier than the Cerium’s Arato nylon. Combined with the overall puffiness of the Cerium SV, it just looks like a totally different garment than the Cerium. Only you can decide what style and function best suits your needs.

Features

Hood

Both the Cerium Hoody and Cerium SV have down-insulated hoods that are adjustable from a single pullcord at the back. The Cerium’s hood has a snugger fit; the Cerium SV’s hood is much larger and helmet-compatible. Neither hood has a structured visor.

Pockets

The Cerium and Cerium SV both have two zippered handwarmer pockets and a zippered internal chest pocket that also houses their integrated stuff sacks (see below). And while the Cerium’s pockets end there, the SV has a large internal dump pocket for additional storage.

Only the Cerium SV has an internal dump pocket.

Cerium Hoody internal zippered chest pocket

Both the Cerium and Cerium SV have internal zippered chest pockets.

We’ll note that the handwarmer pockets are appropriately located behind the down insulation, but they’re not fleece lined.

Packability

Another benefit of down jackets is their ability to compress into small packages, making it easy to fit them in backpacks for convenient access to reliable warmth on your outdoor adventures. Accordingly, both the Cerium and Cerium SV come with integrated stuff sacks inside their interior zippered chest pockets.

The Cerium Hoody packs down to approximately 8.5 x 4 x 4 inches. The Cerium SV is a bit larger but still impressively compact, fitting in a 9.5 x 5 x 5 inch sack.

Decision-time

There’s a lot to like about the Cerium and Cerium SV jackets, but they are not interchangeable. If you’re looking for a packable, ultralight down midlayer for cold but not freezing adventures, the Cerium Hoody and Cerium Jacket are great choices. They’ll work fine as outer layers in spring and fall, but don’t expect them to suffice as everyday standalone down jackets in frigid weather. The Thorium Hoody or Thorium SV are your better daily down jackets for around-town use in below-freezing conditions.

The Cerium SV is a super puffy, deceptively warm outer layer for cold weather. Wear it with confidence in mostly dry conditions when warmth is at a premium, just don’t plan on it fitting underneath a weatherproof shell. It’s also extremely compressible, making it a great choice for backcountry adventures when weight and space are at a premium.

Arc’teryx Fissile SV Down Jacket review | A down-insulated oven for skiers

Last updated: November 4, 2024 by Brent Boyer

The all-new Arc'teryx Fissile SV Down Jacket adds to the brand's growing lineup of men's all-weather insulated ski and snowboard jackets. The goose down-insulated, Gore-Tex-protected Fissile SV Down Jacket is marketed as Arc'teryx's warmest jacket for days churning laps at the resort. It's competition includes the Beta Down Insulated Jacket, the Macai Jacket, the Sabre Insulated Jacket, and the Rush Insulated Jacket. It should be noted that the Andessa Down Jacket is the women's counterpart to the Fissile SV. The jackets share nearly identical specs, save for a couple relatively minor differences we'll share in our review below.

Before we do our deep dive, here's how Arc'teryx compares the Fissile SV Down Jacket to the aforementioned others: https://arcteryx.com/us/en/compare/X000008481/X000007183/X000007394/X000007447/X000007315

Warmth & Insulation

We'll get to the merits of insulated ski jackets in a moment. But make no mistake, the Fissile SV Down Jacket for men and the women's Andessa Down Jacket have been designed to keep you toasty warm on even the coldest lift-served ski days.

Arc'teryx has packed 195 grams of RDS-certified 750 fill-power European grey goose down into this jacket, and supplemented it with 100gsm PrimaLoft Silver polyester synthetic insulation in strategic areas like the shoulders, neck, cuffs, hood and underarms. Why synthetic insulation? Because for all its amazing insulating properties, natural down is relatively worthless when wet. Which is why Arc'teryx uses synthetic insulation - which doesn't lose its insulating properties when wet - in areas of your jacket prone to moisture build-up.

The Fissile SV Down Jacket features stitch-free baffling, which Arc'teryx says improves the integrity of the Gore-Tex. No stitch holes = no compromising the waterproof membrane.

All that nice grey goose down in the Fissile SV and the Andessa comes at a price (and we don't just mean the $1,100 sticker). This thing weighs more than 2 1/2 pounds - great for cold days chasing vert via lifts but not for any sort of touring or backcountry adventures. The Fissile SV is too warm for any medium- or high-output activities anyway, which brings us back to insulated vs non-insulated ski jackets.

As a general rule, we prefer shells over insulated jackets for skiing and snowboarding. Why? Because we like being able to customize our layers to each day's conditions. A good shell provides a waterproof and windproof outer layer, but what we wear as a baselayer and mid layer is entirely dependent on the day and our planned activities. If, however, you like the idea of easy, reliable warmth on consistently cold resort days, then an insulated jacket may fit your needs just fine.

Unless it's a guaranteed bluebird day, you want to know your ski jacket can withstand whatever Mother Nature throws your way. That's particularly true if your ski jacket is insulated with down (remember, down insulation and moisture often don't play nice).

For the Fissile SV Down Jacket, Arc'teryx has opted for the new 3L Gore-Tex ePe Gen 2 waterproof and windproof membrane. The "3L" means it's a three-layer laminate featuring the waterproof/windproof/breathable Gore-Tex membrane sandwiched between a face fabric and a lining. The second-generation ePe is Gore-Tex's newest iteration of its PFAS-free material. Arc'teryx says all its Gore-Tex garments have a water column rating of 28,000mm, which means they can truly withstand any amount of water (in the form of snow, rain, sleet) and pressure you could conceivably encounter in the real world.

A three-layer (3L) Gore-Tex fabric features the waterproof and breathable membrane laminated between a face fabric and a liner.

At 80-denier, the face fabric of the Fissile SV and Andessa down jackets is burly enough to hold up to the abuses of resort skiing - from the rubbing of your ski or snowboard edges against your jacket on the walk to and from the lot or lodge, to the occasional slaps and scrapes of tree branches as you search for untracked. The lining is a 15-denier recycled and downproof nylon, which will keep those pesky feathers from escaping their baffled homes.

Finally, the Fissile SV Down Jacket's face fabric is coated with a FC0-DWR finish, which is also free of PFAS (aka forever chemicals). DWR (Durable Water Repellent) finishes are what cause water to bead up and roll off your technical outerwear, and they need to be reapplied every so often as your jacket gets dirty or oily from regular use. Scroll to the bottom for care instructions for your Fissile SV Down Jacket (and any other Gore-Tex down insulated jacket in your closet).

In terms of the breathability of the Fissile SV Down Jacket - i.e., how well it allows moisture and sweat to escape the inside of the jacket - don't expect much. First, consider the high-loft down insulation throughout the jacket and remember that moisture doesn't play nicely with down. It doesn't matter whether that moisture is in the form of precipitation or perspiration.

Second, and perhaps more important, you shouldn't need the Fissile SV Down Jacket to be very breathable. It's intended use is for very cold days riding the chairlift at your favorite resorts. Lift-served skiing and riding is a fairly low-output activity and therefore it should be difficult to wet out the inside of your Fissile SV from perspiration. But if you do need to dump some heat, we appreciate that Arc'teryx included pit zips on the Fissile SV for exactly that purpose. As a bonus, the pits are mesh backed to prevent snow from getting inside your jacket when they're open.

Fit & Finish

The "regular" fit of the Fissile SV Down Jacket is supposed to means it's roomy enough for the requisite underlayers but not so bulky that it restricts your movement on the slopes. However, I found the size medium (my go-to size for all Arc'teryx items) to be surprisingly snug. I could comfortably wear a fitted, next-to-skin baselayer under the Fissile SV, but there's no way any additional (or thicker) layers could be accommodated. One could make the argument that multiple layers aren't typically needed with a super warm down jacket like the Fissile SV or Andessa. In my case, it wouldn't be an option regardless.

We'll also note that Arc'teryx has incorporated a snowsport-specific articulated pattern in the Fissile SV and Andessa jackets in an attempt to achieve an appropriate balance of mobility and comfort. Just know that you will sacrifice mobility when wearing a high-loft down jacket like this.

Hood

The Fissile SV's hood is insulated, adjustable with a single pullcord, and helmet compatible. We also appreciate that it's removable, because there are some days you just don't want or need the added bulk of an insulated hood hanging off the back of your jacket.

Yep, it fits over your helmet for warming up on lift ascents.

Pockets

From energy bars to apres-ski beanies to car keys and a phone, there's always a need to stash goodies close to your body for a day at the resort. The Fissile SV Down Jacket's pockets are more than capable of doing the job.

The jacket has two zippered handwarmer pockets - and we love their placement. These roomy pockets are higher up than traditional waist-level handwarmers, offering convenient access when sitting on the chairlift.

See how the zippered handwarmer pockets are situated near your ribs instead of your waist? Great for access while lift riding.

The Fissile's other external pocket is a small zippered pocket on the lower left forearm. This is where you keep your RFID season ski pass for easy, no-hands lift access.

On the inside of the jacket is an internal chest pocket and two large internal dump pockets - great for stashing bulkier extras like a balaclava or beanie for apres-ski adventures. The Andessa Down Jacket for women has only one internal dump pocket.

Powder skirt

Proving its snowsport-specific nature, the Fissile SV Down Jacket and the Andessa Down Jacket come equipped with the requisite powder skirt. We like that it's removable, because as much as we wish every day were a powder day, that's just not the case.

Don't know what a powder skirt is or why you might need/want one? We go into detail here: https://outdoorcrunch.com/powder-skirts

Zippers

We mentioned it above, but the Fissile SV Down Jacket includes mesh-backed pit zips for ventilation without snow entry.

The jacket's two-way front zipper is also protected by a button-down storm flap to keep any wind or snow from sneaking through. It's an appropriate detail given the stated objective of the Fissile SV and Andessa down jackets being the warmest resort jackets offered by Arc'teryx.

Collar

Whether or not you remove the Fissile SV's hood, the down-insulated collar sits high and comfortably around your neck to keep the warmth in and the weather (mostly) out.

Note the Fissile SV Down Jacket collar's independence from the removable hood.

How to care for your Fissile SV Down Jacket

Down is such an incredible insulator because of the tiny pockets of air within it that trap your body's heat and thus keep you warm. But when down becomes wet it loses its insulating power and is essentially worthless. It also takes a long time to dry. All of this is to say that caring for your down garment is essential to keeping you warm and to making sure that expensive jacket performs for years and years.

There's no need to wash your Fissile SV Down Jacket or other down garments until you know or see that it's dirty, and that's because things like dirt and sweat compromise the ability of your jacket's high-end fabrics to repel moisture.

When it is time to wash your down jacket, here's what Arc'teryx recommens:

Close the main zippers but leave open pocket zippers (and make sure all those pockets are empty
Release the tension on any drawcords, like the one for your hood
Loosen and secure any Velcro cuffs
If you have a top-loading washing machine with an agitator, toss your garment in a mesh bag to help protect it
Use a mild detergent without scents, dyes or fabric softener, and wash on medium heat with a permanent press or gentle setting. Add an extra rinse cycle to ensure all the detergent is washed out. This down detergent from Nu is recommended and sold by Arc'teryx.
If you need to refresh your jacket's DWR (durable water repellent) finish, this is the time to do it. Close all zipper, hang up your damp garment, and spray the DWR evenly and thoroughly across the outside of the coat. Arc'terx recommends this Nu Durable Water Repellent spray.
When finished washing, turn the jacket inside out and put it in the dryer on a low heat setting. Add two clean tennis balls or other dryer balls to help the down regain its loft. Note you may want to turn the jacket inside out again to ensure all areas of the down get completely dry.

Voilà! Your Fissile SV Down Jacket is hopefully as good as new.

Arc’teryx Allium Insulated Jacket | First look at the new freeride softshell

Last updated: January 10, 2025 by Brent Boyer

Layering up with the Arc'teryx Allium Insulated Jacket at Copper Mountain, Colorado

The more I've worn the Arc'teryx Allium Insulated Jacket this ski season, the more I like it.

Of all the Winter 2024 products Arc'teryx released in early October, the brand new Allium Insulated Jacket is one of the most intriguing. Arc'teryx positions the hoodless softshell Allium as a midlayer or standalone option for skiers and snowboarders. It's certainly comfortable, and its clean, straightforward design works as well off the slopes as on. But if you already own a quality Arc'teryx synthetic insulated layer - perhaps an Atom or Proton - where does (or even should) the Allium Insulated Jacket fit in your closet?

First, here’s how Arc’teryx compares the Allium to some of those aforementioned models, including the Atom SL, the Atom Jacket, the Proton Hybrid Hoody, and the Proton Hoody: https://arcteryx.com/us/en/compare/X000009161/X000006731/X000005409/X000007349/X000008436

A great ski and snowboard shell keeps you dry from the elements and protected from the wind, but it offers next to zero warmth. This is why proper layering is essential to being comfortable on the slopes, whether you're backcountry touring or pounding out resort laps. Arc'teryx has no shortage of synthetic insulated midlayer options; nonetheless, for Winter 2024 it introduced the Allium Insulated Jacket.

The Allium's "regular" fit means it's loose enough to wear over baselayers but not so baggy that it will bunch up under your shell. And while the Allium does indeed fit fine under my Arc'teryx Sabre SV and my Patagonia StormShift, for example, it's noticeably roomier than other Arc'teryx insulated midlayers in my closet - including the standard weight Atom and Proton hoodies. I'm reliably a size medium in every major outdoor brand, including Arc'teryx, and I was surprised at how much looser the Allium fit than all my other midlayers. I even double-checked the label to make sure I hadn't accidentally picked up a size large.

The Arc'teryx Allium Insulated Insulated Jacket was designed to be worn as a midlayer or standalone outer when skiing and snowboarding. But it's straightforward styling and relaxed fit works well for aprés activities as well.

In that same vein, the Allium's collar is spacious around the neck, even when fully zipped. It makes sense, given the Allium's snowsport-specific role and thus the need to comfortably accommodate high-necked baselayers. Finally, the Allium is hoodless, another indicator of its position as a ski-specific layer. Its Coreloft synthetic insulation won't lose warmth if it gets wet, and the PFAS-free durable water repellent finish will help water bead up and roll off.

So how does the Allium compare to some of our favorite Arc'teryx synthetic insulated pieces, like the Atom SL, Atom Hoody, Proton, and Proton Hybrid Hoody, especially for days on the slopes? More on that below.

Snowboarding with the Arc'teryx Allium Insulated Jacket as a midlayer for the Sabre SV shell

The Allium Insulated Jacket pairs nicely as a midlayer with the Arc'teryx Sabre SV shell, our choice as the Best Arc'teryx Ski Jacket for extreme conditions.

Warmth / Insulation

Most Arc'teryx jackets that use synthetic insulation feature the brand's proprietary Coreloft insulation. This is what you'll find in best-selling Arc'teryx product lines like the Atom and Proton (read our Atom vs Proton review). Interestingly, the new Allium Insulated Jacket features a synthetic insulation called Comfortemp Stretch, a recycled polyester chopped staple insulation produced by Freudenberg Performance Materials.

Similar to how Arc'teryx employs different weights of Coreloft insulation in different areas of a jacket, so too is the case with the Allium. Arc'teryx uses a Comfortemp Stretch 40gsm in the core body area, and a Comfortemp Stretch 25gsm in the Allium's sleeves. The difference in insulation weight isn't noticeable when wearing the Allium, for what it's worth.

Arc'teryx Allium Insulated Jacket front and inside view

There's very little bulk to the Allium, which uses a relatively lightweight synthetic insulation.

One of the biggest advantages of synthetic insulation, be it Coreloft, Comfortemp, Primaloft, etc., is that it doesn't lose its insulating properties when wet. This is why brands like Arc'teryx often employ synthetic insulators in their activewear clothing. So whether your jacket gets wet from snow, rain, or your body's own perspiration, synthetic insulation will continue to do its job and keep you warm. This is not the case with down insulation, which is why it's less frequently used in jackets and layers worn during high-output activities.

Another note about the warmth of the Allium Insulated Jacket: as mentioned above, it is cut noticeably larger than other popular Arc'teryx midlayers. That more relaxed fit certainly makes it comfortable to wear and easy to layer, but it may be off-putting to those who prefer their activewear to have an athletic, or trim, fit. We should note that a roomier fit also allows more air to be trapped between your body and the Allium Insulated Jacket, adding to its insulating effect.

We've worn the Allium as a midlayer while snowboarding in conditions ranging from snowy and downright frosty (low teens Fahrenheit) to sunny and moderate (temps in the 30s). In combination with a good merino wool baselayer and a weatherproof shell - we've tested the Allium under the Arc'teryx Sabre SV, Arc'teryx Rush, and Stio Environ ski jackets - the Allium Insulated Jacket has kept us comfortable.

Breathability & Ventilation

A jacket's breathability is typically determined by a few factors: the type of face fabric used, the type of liner used, the kind and amount of insulation, and mechanical venting options like zippers, pit zips, fleece side panels, etc.

The Arc'teryx Allium Insulated Jacket's face fabric is a 50-denier recycled stretch nylon in a plain weave. While nylon itself is not a very breathable material, the use of a stretchy plain weave will help with the circulation of air, and the choice of a 50-denier fabric means it will better stand up to abuse the Allium might take when worn as an outer layer (ski edges, rogue branches, metal chairlift backs, etc.). The jacket's lining is a 20-denier recycled nylon, also stretchy and in a plain weave.

The plain weave of the Allium is soft and smooth to the touch while providing enough stretch for activities like skiing and snowboarding.

Mechanical ventilation on the Allium is limited. There are no armpit zippers to help dump heat, and the jacket's main zipper is one-way only. There are no fleece side or back panels, either. Stick with the Atom SL or Proton Hybrid Hoody if you require maximum breathability.

Considering the Allium Insulated Jacket's intended use - skiing and snowboarding - it's not ideal for high-output activities like running or even ski touring. Its sweet spot is days riding lifts at your favorite resort.

Allium Insulated Jacket: Fit

As mentioned above, the Allium is cut with a noticeably more relaxed fit, which makes it easier to wear on top of baselayers without being so bulky as to not fit cleanly under your preferred shell. But it's a little too loose for my liking. I prefer the slightly trimmer fit of the Atom and Proton lines, which both still allow for a next-to-skin baselayer.

The body of the Allium is very roomy.

Nonetheless, it fit under a shell without bunching.

We like that Arc'teryx skipped the hood on the Allium. A hood just isn't typically necessary - and often simply adds bulk without benefit - for ski and snowboard midlayers. Our shells almost always have helmet-compatible hoods, anyway.

It also works that Arc'teryx made the collar on the Allium Insulated Jacket looser-fitting than collars on many of other midlayers. Why? Because a looser collar makes it easier and more comfortable to wear high-necked baselayers when skiing and snowboarding. My Smartwool 250-weight merino wool baselayer, which rises to mid-neck, fits great under a fully-zipped Allium with no noticeable neck restriction.

Allium Insulated Jacket: Features

Pockets

The two zippered handwarmer pockets are spacious and feature hidden zippers, which add to the clean look of the Allium when its worn as a standalone outer layer. The jacket also has a single zippered chest pocket, which fits your smartphone or other small valuables. There are no internal pockets on the Allium Insulated Jacket.

Adjustable hem draw cord

Perhaps more so than with other midlayers, the Allium's dual hem adjustment cords are a welcome touch. Why? Because that roomier fit means more space for wind, cold air, and snow to sneak in. Snugly cinch up the hem when you're on the slopes, and thank us later.

Is the Allium Insulated Jacket worth it?

Should you drop $300 on the Arc'teryx Allium Insulated Jacket? If you lack a reliable midlayer for skiing or snowboarding and you don't mind spending the money on a jacket that isn't particularly well-suited for other high-output sports and activities, the Allium is a perfectly good choice. Truth is, we've come to like this jacket more each time we wear it, and it's become a go-to for resort days.

But, if you already own a good, hoodless synthetic insulated midlayer (say, an Atom or Proton, for example), the Allium is probably superfluous.

Arc’teryx Shoes | Sylan, Sylan Pro, and Sylan GTX Review

Last updated: September 16, 2024 by Chris Tamucci

Trail testing the Sylan Pro, the Arc'teryx shoes built for fast mountain running.

Runner on a trail with the Arcteryx Sylvan Pro Arc'teryx shoes

The Arc'teryx Sylan Pro is part of the new for 2024 Sylan series, released from the brand's dedicated shoe design center in Portland, OR. We took this shoe on a number of runs and give our insight, as well as cover the similarities and differences between the Sylan, Sylan Pro, and Sylan GTX so you can choose the Arc'teryx shoes that are right for you.

Check out our other coverage of Arc'teryx footwear

Sylan, Sylan Pro, and Sylan GTX

Trail racing and running

Mountain running shoe designed for maximizing speed.

The Sylan Pro sports a large identity fossil logo on the upper. The integrated tongue pocket with lace tab keeps this shoe feeling tight.

MSRP: $200 (Sylan and Sylan Pro) $230 (Sylan GTX)
Waterproof: Yes (GTX)
Weight per shoe: 292g (Sylan and Sylan Pro) 310g (Sylan GTX)
Drop: 6mm (28.6mm : 22.6mm)
Sole: Vibram® Megagrip w/ Vibram® LiteBase
Midsole rocker, InFuse® midsole
Default fit: Comfort

The Arc'teryx Sylan series shoes are all about fast mountain running.

These features are common across all Sylan models.

Midsole rocker - Found on race shoes, a rocker increases propulsion during stride transition.
Lug pattern - 6mm lugs are the deepest found on Arc'teryx trail running shoes and are spaced wide for grip in mud. The lug pattern is specially designed for steep terrain.
Drop and stack: 6mm (28.6mm : 22.6mm) We'd call this a mid-high stack height, so you're getting both cushion and ground feel.

The Sylan GTX is the waterproof offering in this line with the familiar GORE-TEX membrane found across Arc'teryx shoes. The application in this shoe is described as a full liner with Invisible Fit Technology to improve flex and comfort.

Fit: This shoe is designated as a default Comfort fit. Be sure to read through the detailed explanation in this article of what this fit means. My advice is to measure your foot in cm. If you like the roomier Comfort fit then stay true to your cm size in the Arc'teryx shoe fit chart (not your U.S. size). If you like a more Precision fit, then go a half size down. I prefer a Precision fit and in the end this will be a full size down in U.S. sizing compared to the other running shoes in my closet.

Bonus points: The tongue pocket stows laces out of the way so you don't snag them on brush, or have them come untied. There is also a lace tab that latches over the highest lace-cross and keeps the tongue in place. Having run a lot in the Sylan Pro, these are small details that make this a great shoe.

The difference between the Sylan Model Arc'teryx shoes

There are only a few differences between these shoes. The Sylan and Sylan Pro only have cosmetic differences from each other. Originally used by their sponsored athletes, the Arc'teryx Sylan Pro sports a large version of the fossil logo on the upper. Besides color options and the logo, the Sylan Pro is identical to the Sylan in all ways (including price).

The Sylan GTX obviously includes the GORE-TEX membrane for waterproof protection. Notably though, this shoe has a Nylon weave upper as opposed to the Matryx® Micro upper found on the other two Sylan models. The tradeoff in this case is 18g additional weight on the GTX. You're not going to notice a difference, but we mention it because this is a departure from what we see on the Vertex Alpine and Norvan LD 3 models when it comes to GTX vs. standard model.

Summary:

Sylan and Sylan Pro are identical except for the color options and the larger logo found on the Pro.
The GTX adds GORE-TEX and weighs 18g/shoe more than the other two models because it uses a Nylon upper and not the Matryx® Micro upper.

Understanding how Arc'teryx Shoes Fit

While Arc'teryx uses standard methodology to measure the length of your foot (back of heel to tip of longest toe), their fit designations for select shoes is unique.

Here is a link to Arc'teryx's shoe size chart:
https://arcteryx.com/help/sizing/footwear

Here are their descriptions on their three fit types. These are applicable to the Sylan, Vertex Alpine, and Kragg models.

Comfort Fit - This gives you the most space at the toe and a less snug fit around the foot.

Precision Fit - This fits snug across the width of the foot with slightly less space in front of the toes.

Technical Fit - This is the most snug option for fit. Picture the fit of a climbing shoe or ski boot.

The Sylan series has a default Comfort fit. Here is the guidance from Arc'teryx when fitting shoes with a Comfort fit:

Arcteryx how to choose your shoe size with a default comfort fit

My take: I'm a little surprised that a shoe like the Sylan Pro, which is made for fast trail running, would default to a Comfort fit. I've always liked Altras for the room in the toe box, and this fit does provide that. In practice, though, I ended up sizing down a half size U.S. compared to other brands and still ended up with a Comfort fit. I pulled out my Nike Zoomfly, Hoka Mach 6, Altra Timp 2, and Brooks Launch. All are 10.5 US, 44.5 Euro, and 28.5cm. My Arc'teryx Sylan Pros are 10 US, 44 Euro, and 28cm, and they feel like the Comfort fit described above.

I would be inclined to go a half size down and get the Precision fit and that would put me at a 9.5 US, which I haven't worn since I was a teenager. That said, my foot measures exactly 28cm and that matches the 10 US on Arc'teryx's shoe size chart. I'll also say that after putting 20 miles on the Sylans through rocky terrain I have zero complaints about stability or foot slip. The takeaway here is that you should measure your foot in cm and check the U.S. and Euro sizing on Arc'teryx's size chart. For Comfort fit stay true to your cm measurement.

Comfort and first impressions

Laced tight, the Sylan Pro feels great.

Overhead image of the Sylvan Pro Arc'teryx shoes

You can see the knit collar, lace pocket on the tongue, and some interesting contours from the Matryx® upper.

My first impression trying these on is that they are roomy and borderline too big for me, even with a U.S. size 10 (to my normal 10.5). Once I properly tightened the laces though I have zero slippage so I believe I have the proper comfort fit. The Matryx® Micro upper feels almost like a hardshell jacket; it's pretty unique. It wrinkles in ways that I think make the shoe look too big for my foot, but it also feels very light.

The other thing I noticed when wearing these for the first time is that while I really like the feel of the rocker, these shoes accentuate my pronation. I over pronate and when wearing the Sylan Pro my ankle collapses noticeably during my stride. As other over-pronators can appreciate, I don't stick to just structure shoes meant to correct pronation. For example, I trained for and raced my last long-distance triathlon (injury free I might add) in a set of Nike Zoom Fly. I've learned to let comfort and feel be my guide. So I decided to give the Sylan Pro a chance. Overall I thought they felt great laced up. The trail would reveal all.

Running in the Arc'teryx Sylan Pro

Arcteryx Sylvan Pro shoe shown on a rock path.

My first test run was directly after an afternoon shower and made good use of the Vibram® Megagrip sole.

I took these on two runs for my initial round of testing. The first was a spin on my local Emerald Mountain trails just after an afternoon shower. The trails on Emerald are notorious for turning to sticky clay when wet and can be tough for running or riding. Some of the hardpack trails can also become treacherously slick. In other words, a great first test for these shoes. The Sylan Pro performed great; it is confident across wet rocks and slick downhills. This was my first experience with both Vibram® Megagrip and Vibram® LiteBase technology. The Megagrip compound is quite tacky. The Litebase cuts the thickness of a sole in half compared to typical trail footwear. What I noticed is that the shoe has great flex and responsiveness. Nimble is the adjective I kept turning over as I ran. The rocker gives some propulsion; this definitely feels more like a race shoe compared to something like the Norvan LD 3. I love race shoes but as I mentioned, my ankle collapses in these shoes due to my pronation. I was hoping that it wouldn't be as noticeable when running, but that was overly optimistic. I ran for an hour and while I definitely notice ankle collapse, I didn't feel any strain. In the hours and day after the run I didn't have any pain whatsoever, so I figured it was worth a second run to give a full assessment.

My first run had freshly soaked trails.

An image of the soles of a pair of Arcteryx Sylvan Pro shoes caked with mud.

The mud on Emerald Mountain dries to something like concrete. The soles performed admirably.

My second run was on rockier trails and through aspen groves at 8000' in the Routt National Forest. I was immediately impressed again with how responsive the sole is on the Arc'teryx Sylan Pro. Overall the construction of the midsole, stack height, etc... provides cushion without totally dampening ground feel. The upper feels light and super breathable. I'm starting to get used to the Matryx® material.

What I like about the Arc'teryx Sylan Pro

Knit collar and tongue - Fully laced, this shoe feels great. The knit collar is comfortable and keeps out dirt and pebbles while on the trail.
Outsole - I think I've said this enough, but these shoes made me a huge fan of Vibram® Megagrip with LiteBase.
Responsiveness - Light and springy. This shoe has the feel I look for in my race shoes.

What doesn't work for me

Comfort Fit - Diving into to the fit descriptions on Arc'teryx shoes and running in the Sylan Pro has made it conclusive; I prefer a precision fit.
Rocker and support - I like the propulsion of the rocker on this shoe, but I think the contour of the heel causes too much ankle collapse for me to put big miles on these. It's a personal dynamic, but I strongly urge anyone that over pronates to try these on before buying.
