Arc’teryx Alpha Parka Review

Last updated: December 14, 2022 by Canberk Koksal

The release of Alpha Parka once again revealed the reason why Arc'teryx as a brand is the Apple of the technical outerwear industry. The products they launch are so far beyond today's textile technology that their designs orient the direction of the evolution of jackets. 


Alpha Parka (Men's - Women's) is the warmest jacket Arc'teryx has ever manufactured. 

Its 296 grams of 800 FP down provides extreme warmth, and makes the Alpha Parka the loftiest Arc'teryx down jacket of all time, standing at 251,600 cubic inches (=296 x 800) of total fill. 

On top of that, this absolute unit of a parka is also reinforced with a whooping 90 gsm of Coreloft synthetic insulation, which is extraordinary when you look at the industry standards from this point of view. 

As if all these aren't enough, together with its cousin Alpha Lightweight Parka (Men's - Women's), Alpha Parka is also the only Gore-Tex down jackets Arc'teryx has ever manufactured. 

I know. Just shot after shot with no pause. Hard to believe how rich this jacket is in terms of performance and capability. 

Bring all these together and you get a jacket that almost looks and feels like it's from the future... and of course, a staggering price tag in return.

No other jacket impresses me even nearly as much as the Alpha Parka (Men's - Women's). As long as it's dry and extremely cold out there, it can be counted on without any second thought. Not only is it the warmest Arc'teryx jacket of all time, it's also the only Gore-Tex Arc'teryx down jacket that Arc'teryx has ever manufactured. 

It also stuffs into itself and comes with a two way zipper to allow for more comfort and mechanical venting where needed, which makes it one of the most versatile jackets out there (hiking, mountaineering, ice climbing, walking around town, you name it). The only downside to this astonishing item is its staggering price.

Warmth

Arc'teryx Alpha Parka is the warmest jacket Arc'teryx has ever manufactured.

As if 296 grams of 800 FP down wasn't enough, this absolute unit of a parka is also reinforced with a generous 90 gsm of Coreloft synthetic insulation in moisture heavy areas.

View full table at https://outdoorcrunch.com/best-arcteryx-jacket/. 

If you're confused now and don't know which jacket best corresponds to your own needs, then follow the advice given in https://arcteryx.com/us/en/shop/jacket-finder/. 

The temperature ratings in this list are intended to represent the lowest temperatures you can wear each jacket without feeling uncomfortably cold. 

Keep in mind that these are only approximate values, assuming: 

  • worn over a shirt only and no shell over, 
  • during daily use (strolls, power walks etc at most - no high output activities), 
  • with light wind, 
  • and when it's dry out.

These values applicable to your torso only. Your hands, legs and feet are still subject to their own additional insulation.

The best practice is usually to use this table for comparing each jacket to one another, rather than pinpointing their ratings. 

Also, ratings will best respond to males. As most women tend to run colder than men, for women, shifting these ratings a bit is recommended. 

Always opt for the warmer option when in doubt. For jackets with Atom AR level warmth and beyond, recommended is almost always the hooded models.

One of the important things in here is that you don't necessarily have to be exposed to extreme colds to need an extremely warm jacket. Let's take a look at the two most common scenarios when it comes to this. 

First of all, for whatever reason, every now and then, most of us tend to stay outside for long periods of time without moving. Not moving will always make you feel much colder as your body do not generate any heat as an output, and hence the jacket cannot heat you up. 

  • Is Alpha Parka meant to replace Ceres SV and Firebee AR?

There hasn't been any official statements about this so no one knows. 

But more importantly, whether that was the case or not, Alpha Parka turned out to be a much superior item compared to both Ceres SV and Firebee AR (read my comparison of the two). The overall improvement is tremendous and almost completely unexpected. 

Another most common instance that extremely warm jackets can come beneficial is when you stay hungry for long periods of time. 

This can be because you might be on a diet and intermittent fasting, or you might be fasting for religious reasons, or maybe it's just what your daily schedule dictates. 

But if you must go out when your stomach is empty for longer than, say, 3-4 hours; it's almost certain that you're going to fell colder than you usually do if you're like most people.

In terms of warmth, there really are no alternatives to Alpha Parka as of now. Cerium SV (Men's - Women's - read my review) is the closest you get, though like I said it's not an alternative and hence the warmth difference will be quite noticeable there. 

If we were to include parkas too, then the Therme SV Parka (Men's - read my review) would be the closest. But it's a parka and not a down jacket, so it's comparing apples to oranges. They're not the replacements of one another. 

Now with all that said, there also of course are (or at least can be) some downsides to this much of warmth. Obviously, overheating is the main risk in here. If you're like me and you tend to run much warmer than the average person, then you're likely to overheat in this jacket even when it's pretty cold. 

This is where the two way zipper steps in. Which brings me to my next point. 

Breathability

Equipping a jacket with pit zips and/or a two way zipper are the only ways to provide mechanical venting. 

  • Mechanical venting > membrane breathability

When it comes to the ultimate breathability one ends up getting from a jacket, mechanical venting hands down is always a bigger factor than membrane breathability. 

Excluding the Atom line (Atom SL (read my review), Atom LT (Men's - Women's - read my review) and Atom AR (Men's - Women's - read my review)), which are equipped with mesh panels and not zips in the armpits, Arc'teryx never offers pit venting in their synthetic insulated or down jackets. 

This is a fact and other brands too position their catalogue similarly in this manner. 

Insulated & shell hybrids like Beta Insulated (Men's - Women's - read my review) and Macai (Men's) do not count. Because they're a shell jacket first and an insulated jacket second. 

It's Arc'teryx shells where you'll find a bunch of jackets with pit zips - although just like most of you I too am not 100% happy with the amount of Arc'teryx shells with pit zips and would like to see them more common. 

Two way zippers in insulated jackets also aren't that common, although certainly more so than the pit zips. 

It's great to finally see Arc'teryx heading towards the use of two way zippers. In addition to our Alpha Parka, the new Thorium Jacket (Men's - Women's - read my review) and Thorium Parka (Men's - Women's) (these are NOT Thorium AR (Women's - read my review), by the way) also feature a two way zipper. 

Two way zipper activated. A great idea for a jacket like this. Really ups the versatility and use cases. 

A two way zipper primarily makes it possible for you to vent out some of the heat you don't need. 

But it's not limited to that. There are two side benefits you get with it: 

  1. Two way zippers can make it a lot more easier for you to access the area around harness and hardware during most outdoor activities. 
  2. It also allows for increased comfort when sitting down, as it won't bunch up if you only keep the upper half zipped. 

The biggest downside of a two way zipper is that it's more difficult to work zip and unzip than the regular one way zippers. Especially with thick gloves. Other downside is that it tends to break down a bit easier, though the user also plays a role in here. 

Anyways, let's get back to breathability. 

The membrane itself, 2L Gore-Tex, is also pretty breathable, but mechanical venting will always account for the overwhelming majority of the total breathability of a jacket, no matter what. 

So that's the primary point in here. Always look at mechanical venting first when trying to comprehend the potential breathability of a jacket. 

Weather and Abrasion Resistance

It isn't ordinary for synthetic insulated jackets or down jackets to supply a Gore-Tex membrane. 

We did see Arc'teryx manufacturing synthetic insulated Gore-Tex jackets in the past, such as the discontinued (and still being deeply missed) Fission SV (read my review) and Kappa jackets. 

But for down jackets, this is the first time in history where Arc'teryx puts a Gore-Tex on a down jacket. 

Hood, chest, shoulders, sleeves, and rear hem and equipped with Hadron 2L Gore-Tex Infinium. All the other locations are equipped with N30r 2L Gore-Tex Infinium. 

If you're unaware, two-layer (2L) Gore-Tex fabric is made up of two layers - an outer layer that is typically made of a durable, abrasion-resistant material, and an inner layer that is coated with the Gore-Tex waterproof membrane. 

Gore-Tex face fabric is another item that adds a lot to the versatility to the Alpha Parka. With the help of its Gore-Tex membrane, the Alpha Parka will hold up against precipitation much more than other down jackets. 

But, at the end of the day, Alpha Parka is still a down jacket and will start soaking after, say, 0.5 - 1 hr under, say, average drizzle. 

Momentary contact with the snow or water isn't going to be a problem at all though. The Gore-Tex outer fabric will be more than enough to combat this. On top of that, jacket is also coated with DWR and will bead water perfectly. 

  • What is DWR by the way?

DWR is a coating. 

It's basically sprayed on to the surface of these jackets as a finish. It stands for Durable Water Repellent - which means that water will be repelled under wet conditions instead of soaking into the fabric. 

DWR also decreases dry time. 

It's a good thing these jackets are coated in DWR, but pay attention to the fact that DWR is a coating - meaning that it will wear off over time. 

Which is why you might want to invest in a DWR spray such as this one for after treatment. 

As you see, there's a strong correlation between FP x FW and temperature ratings, but not more than, say, 80%. I explained why this happens here in this post of mine. 

Pockets

2 hand warmer, 1 external chest and 2 internal drop in pockets offer plenty of storage. Probably even more than you'll need because the internal pockets are enormous. 

Fit

Does this jacket really fit larger? 

Well, yes, but that's limited to the torso. It does fit true to size in the arms and shoulders. 

This alone should be enough to discourage you from sizing down, because you risk the jacket to come narrow in the arms and shoulders in that case, which would be a deal breaker. 

I'll take a jacket that fits large in the torso over the one that fits small in the arms and shoulders everyday. 

But, in addition to this, another factor you should also consider is layering and warmth. As you can also see in this article where the working principles of down jackets are explained, air makes up as an amazing insulator. And in case you would like to layer this jacket, the added warmth you'll end up getting will be much more than a more slim jacket. 

Alpha Parka is like a base layer, a mid layer and a shell all put together in one piece. Still, depending on your personal needs and desires, you might want to layer it. 

Best uses

Alpha Parka is marketed as a climbing jacket. But you can absolutely use it just about for anything - hiking, climbing, walking around town (casual use), etc. People even use it for skiing (speaking of which, if you're interested in Arc'teryx ski jackets, read this article). 

As long as nothing more than a little protection against precipitation is expected, I really can't think of any scenario where the Alpha Parka wouldn't be ideal.

Conclusion

If you can afford it, I can recommend the Arc'teryx Alpha Parka my eyes closed. It's a breathtaking down jacket you'll appreciate having over and over again.

Arc’teryx Thorium Review

Last updated: November 14, 2022 by Canberk Koksal

The name of Thorium AR has been changed to Thorium for winter 2023. There has also been some design updates: 

  • A two way zipper is added, which to me is the main (and the strangest) highlight, 
  • An external chest pocket is added, 
  • Fit is now a little bit baggier, 
  • Baffles are a bit larger (see image below), 
  • Hood is now helmet compatible, 
  • Amount of 750 FP down is increased from 130 grams to 140 grams,
  • Made more eco-friendly. 

There has also been subtle changes in the weight (slight increase) and center back length (slight decrease). Check out the jackets database table below for more details about them. 

Thorium Parka is also just in! Here's the Thorium vs Thorium Parka vs Thorium AR side-by-side comparison page on arcteryx.com: https://arcteryx.com/us/en/compare/X000006585-bitters/X000006919-black/X000006972-figment

Arc'teryx Thorium vs Thorium AR. I loved the 24k black color of Thorium AR a lot. Click on image to visit the new Thorium Hoody page on arcteryx.com. 

Even if Arc'teryx decides to discontinue the Thorium AR in the future, its second hand will live pretty long because of its popularity and durability. 

Summary

Arc'teryx Thorium is a fantastic, warm down jacket for casual use in dry areas. It's comfortable, light, stuffs into itself and is even equipped with a two way zipper. 

I wouldn't recommend it for damp areas at all though. Because it soaks water like a sponge (as all down jackets do). Don't think about it for high output activities either (fragile face fabric and poor breathability). 

FYI, Thorium isn't the only down jacket line Arc'teryx offers. There's the Cerium line, too - which is a lighter and less warm alternative to it.

Warmth

Thorium is pretty warm, especially for its weight. This isn't surprising news for any down jacket as they offer incredible warmth to weight ratio.

View full table at https://outdoorcrunch.com/best-arcteryx-jacket/. 

If you're confused now and don't know which jacket best corresponds to your own needs, then follow the advice given in https://arcteryx.com/us/en/shop/jacket-finder/. 

The temperature ratings in this list are intended to represent the lowest temperatures you can wear each jacket without feeling uncomfortably cold. 

Keep in mind that these are only approximate values, assuming: 

  • worn over a shirt only and no shell over, 
  • during daily use (strolls, power walks etc at most - no high output activities), 
  • with light wind, 
  • and when it's dry out.

These values applicable to your torso only. Your hands, legs and feet are still subject to their own additional insulation.

The best practice is usually to use this table for comparing each jacket to one another, rather than pinpointing their ratings. 

Also, ratings will best respond to males. As most women tend to run colder than men, for women, shifting these ratings a bit is recommended. 

Always opt for the warmer option when in doubt. For jackets with Atom AR level warmth and beyond, recommended is almost always the hooded models.

When it gets soaked in water (e.g use under precipitation), not only it lets the water in, but it also loses insulating power. That's because down provides warmth by trapping air in its vacant spots, and water, as you can guess, interferes with that mechanism. 

If you'd like to read more about the working principles of down insulated jackets (or synthetic insulated jackets for that matter) check out this article: https://outdoorcrunch.com/jackets/ 

In addition to down, Thorium is also insulated with Coreloft, a synthetic insulator made by Arc'teryx. Just like all synthetic insulators, Coreloft too is much more weather resistant compared to down, and doesn't lose insulating capability under wet conditions. 

If you'd like to read more about Coreloft and other synthetic insulators as well as their working principles, check out the article https://outdoorcrunch.com/clo-values/ in addition to the article I've shared above.

This brings me to the next point. 

Weather & abrasion resistance

The point of reinforcing a down jacket with synthetic insulators is to provide it at least a little bit of a weather resistance. Because no matter where you live, you don't want to be completely vulnerable to unexpected weather changes. ZERO protection against precipitation is usually unacceptable. 

Reinforcements made in Thorium accomplishes this pretty well. 

My girlfriend wearing my Thorium AR (which, as explained earlier, is NOT the most recent model) in Jokulsarlon, Iceland during late March (2022). On a side note, here's the article on our trip to Iceland. 

We experienced all sorts of snow, rain and drizzle (welcome to Iceland in March) and Thorium did a pretty good job in terms of withstanding it for, say, up to half an hour on average. 

If you need a much more weather resistant jacket with at least the same amount of warmth, then you must forget about down jackets. I'd recommend you to check out Nuclei SV (Men's) and Atom AR (Men's - Women's - read my review) in that case. 

In terms of wind resistance, it's solid and won't cause you any problems, although it's not as solid as wind-proofing focused jackets such as the Nuclei FL (Men's - Women's - read my review). 

Breathability

Thorium is the first of its kind in this regard. 

It's the first light-Arc'teryx-down-jacket that is EVER offered with a two way zipper. 

I've long been mad about Arc'teryx's approach on two way zippers, especially for men's counterparts (almost all of women's parkas offer one but this isn't the case for men's parkas, for example). 

I didn't expect a move like this. Thank you Arc'teryx! 

Now there is a downside to having a two way zipper. It tends to break more often and easily. But I don't see this being a problem unless you're planning to use the jacket for 5+ years. 

It also takes a bit more time to zip it up compared to the ordinary one way zippers. Especially if you have gloves. Two way zippers sometimes do feel annoying to me, but the breathability and comfort advantages also cannot be overlooked. 

I also say comfort in addition to breathability in here because being able to keep the only upper half of the jacket zipper and the lower half unzipped, it's so much more comfortable when sitting down. 

The comfort difference in this regard is much more apparent with the longer jackets (mainly parkas), so don't expect day and night kind of difference with the Thorium in this regard since it's a rather shorter jacket. 

Packability

I'm a big fan of jackets that stuff into themselves. 

See the size of my packed Thorium AR (far left - see image). A packed Nuclei FL, a Beats Studio 3 and an Osprey Farpoint 40 for scale. Cerium LT packed size would be close to Nuclei FL. 

One thing to keep in mind in here though is that stuffing and unstuffing a jacket tens of thousands of times can take a toll on its insulating power over time. The ideal way to store a jacket is to hang it.

First thing you should know about down jackets is that you should only consider getting one for stationary use, in dry weather. 

Because, all down jackets offer: 

  • Low breathability, 
  • Poor wet weather performance, 
  • Fragile outer shell.

Always. 

No exceptions. 

If this isn't you, then you should stop reading this post and go check out my Best Synthetic Insulated Jackets article. 

I'd also recommend you to check out my Best Arc'teryx Jackets and Best Patagonia Jackets articles. 

  • Summary & Take-away

Do make sure checking out the given temperature ratings, but still, for most of you... 

My number one recommendations would be from my favorite brand Arc'teryx. Thorium AR (Men's - Women's - read my review) would be my top pick, with the Cerium LT (Men's - Women's - read my review) being the top alternative to it. 

  • I also recommend these two as best down picks for casual use out in variable temperature & variable weather, as you can see in my Best Arc'teryx Jackets post. 
  • Read my Thorium AR vs Cerium LT comparison here. 
  • Cerium LT also offers alternatives: SL and SV. See my Cerium SL vs LT vs SV post to find out how they compare. 

My top non-Arc'teryx pick would be Feathered Friends Eos (Men's - Women's), with Patagonia's Down Sweater (Men's - Women's - read my review) being the top alternative to it.

#Important note: A down jacket will lose its insulating capability under fairly wet conditions. Either from your sweat or wet weather. 

That's why, if you're going to be using them in damp areas, I'd urge you to consider getting a synthetic insulated jacket instead. They're mostly heavier, but perform better in wet conditions.
