Down jackets: Hooded or hoodless? I surveyed 100+ visitors

Last updated: November 9, 2023 by Canberk Koksal

I asked you "Down jackets with hoods or no hoods?".

71% voted for hoods. 29% didn't. Shucks.

Kinda surprised with these results. I belong to the minority in here.

I understand hoods with super lofty, Gore-Tex down jackets like Thorium SV and Alpha, but other than that, I'm camp no hood.

I have a hooded Thorium AR and a hoodless Cerium (formerly LT). I find the looks of hooded down jackets a bit too "sportsy" at times.

I feel hoodless down jackets better suit to more formal looks. Wearing them on top of dress pants look better. My Cerium is in Black Sapphire so the color allows this too.

In the end, my hoodless Cerium is worn more than my hooded Thorium AR.

They're both terrible against resisting water (although the Thorium AR has the slight edge). So I don't even think about putting them on when it's raining anyway. Haven't found myself in a situation where I wished having a hood until now.

Additional obvious benefit of hoodless down jackets is that the hoods don't nest when used in layers. I don't like layering down jackets, so I can't relate.

Arc’teryx Patera Parka Review: Begs for more fill

Last updated: October 25, 2023 by Canberk Koksal

Y'all know this is just my opinion... right?

Pros: Comfy, stylish and streamlined. Superior weather resistance.
Cons: Much less warm than you'd think, tiny snaps, small pockets.

Very low amount of fill and too much potential problems make this item risky.

If you rarely get parkas and coats, think twice before tying the knot with this one.

Overview

My girlfriend has this parka in Lucent. Bought in 2022. It's been a year and she digs the fit and looks.

She's camp minimalism.

Patera's sleek look overlaps perfectly with her taste, unlike the new arrival Arc'teryx Liatris, for example, which comes with too many bells and whistles.

Standing at 750 FP, the fill power might not be low but it certainly isn't particularly high by any means.

She felt warmer in my Thorium AR (image at Jokulsarlon, Iceland).

This is the standard fill power Arc'teryx uses in their parkas like Therme, Thorsen (discontinued), Camosun (discontinued), and Centrale (discontinued).

The 2.35 oz (67 grams) of fill weight, on the other hand, is very low. Ridiculously low, to be precise.

Patera also comes with 60 + 80 gsm Coreloft synthetic reinforcements in areas prone to tear and abrasion.

But even my much-lighter-in-comparison Thorium AR has twice as much down with MORE synthetic fill. Lol.

Thorium AR was changed to Thorium recently and the fill was increased even more (by 10 grams (.35 oz)). So it's even warmer than the Patera now.

We were under the rain for about an hour and the Patera held up nicely. Beaded water and didn't soak.

Now with all that said I don't see anything wrong in getting a jacket with inferior insulation capabilities. Just make sure your expectations are in the right place.

We, for example, live in Istanbul. It does get much colder than you think here. But still isn't comparable to northern NA and EU.

So we've got more wiggle room in terms of warmth and hence the privilege of prioritizing the looks over warmth.

This to me for example is a justified reasoning for paying 800 bucks for this item. If where you live gets much colder you might want to think twice.

The upper arms, upper back, chest and armpits fit snug. Not much room for layering.

My girlfriend is around 5'7", 110-120 lbs with long legs and arms. She's got the size S. She's closer to an XS than an M.

Weather resistance

Only good things to say on this front.

When you've got an almost stitchless outer surface, DWR coating, 2L Gore-Tex, and 39 in (or 99 cm) of CB length, superior water & wind resistance isn't surprising.

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 at arcteryx.com 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.

Snaps

It's worth nothing that the snaps are a bit too tiny. Would like too see bigger snaps like in Therme Parka (Men's - read review).

Close up of snaps.

Tiny snaps makes it difficult to close when you have gloves or cold hands. When pulled they also pop open quickly.

Pockets

There's one internal zippered chest pocket. It's oddly small, just like the hand warmers.

Two way zipper

As much as I love two way zippers, this time it's fiddly to zip up. No problems that require warranty so far though.

Collar

Collar is stiff. If you have short neck, it might rub into your chin or mouth and make it uncomfortable.

Alternatives

The best alternative is the Patera Long (duh). It's not only the longer version. It's equipped with x3 amount of down.

https://arcteryx.com/us/en/shop/womens/patera-long-parka

Thorium Parka is also a great alternative as long as you don't need any resistance against precipitation.

https://arcteryx.com/us/en/shop/womens/thorium-parka

Here's how Arc'teryx compares these three:

https://arcteryx.com/us/en/compare/X000006443/X000006499/X000005685

The once-closest-alternative, the Centrale Parka, (read how it compares to Patera) got discontinued.

There's also the Coelle (Women's) but it's not down insulated.

Patagonia Nano Air 2024 vs DAS Light: Temp ratings & more

Last updated: November 21, 2023 by Canberk Koksal

I've got the most recent (Winter 2024) versions of both Nano Air and DAS Light.

They're both fantastic. But they best respond to pretty different use cases. As long as your expectations are in the right place, neither will disappoint.

Patagonia Nano Air vs DAS Light: Summary

Nano Air is updated for 2024. Disregard the reviews put forward pre-September 2023.

DAS Light is a rather niche item. Although it's meant to be put on when you stop moving (i.e it's a belay jacket), I also wear it casually all the time without any problems.
- Instantly warm and incredibly wind resistant. Horrible breathability and durability. Luckily it comes with a two way zipper (excess heat can be dumped).
- Hem cinch cord and more pockets (preferably internal dump pockets) would be nice additions. Packing on your own is also a bit difficult.
- Alternatives: Arc'teryx Nuclei (aka FL) (Men's - Women's - read review).
Nano Air is one of the most popular and versatile jackets of all time. High output activities is its best use but it's worn casually when it's not too cold.
- Spectacular balance between breathability and warmth. Insanely comfortable to wear thanks to its stretchy structure that allows for mobility. Less noisy compared to DAS Light. Offers average durability and wind resistance.
- A hood drawcord would be a nice addition. Sleeves are a bit long and cuffs aren't as tight as other alternatives like Arc'teryx's Proton and Atom. This can be less comfy if you have very short arms compared to your size AND if you're planning to wear the Nano Air casually. Unless you're these two at the same time, it shouldn't be that much of a problem.
- Alternatives: Arc'teryx Proton (aka LT) (Men's - Women's - read review) and Atom (aka LT) (Men's - Women's - read review).

Both are packable.

Fit

I'm 5'11", 165 lbs, athletic build. Size M fits me perfectly.

My size is always the same. Arc'teryx, Patagonia, TNF, Salomon, Columbia, Nike, Adidas, Under Armour, Zara... Doesn't matter.

Patagonia Nano Air vs DAS Light: Overview

Best use of DAS Light is rather niche. It's a belay jacket. You can see that in Patagonia's URL as well:

https://www.patagonia.com/product/mens-das-light-belay-hoody/85300.html

You're meant to pull the belay jackets out of the bag, unpack them and put them on when you stop moving. The objective is to maintain your core temp.

That's why DAS Light allows for zero ventilation and provides warmth at an instant. That's why it comes with a stuff sack and fits baggier. So that you wear it on top of all your clothes.

But how does it accomplish this? It features 65 grams of PlumaFill. This is equal to the insulation in Micro Puff.

Assumptions: Worn over a thin shirt, no output, no precipitation, light to no wind. Values are always for size M and for men's, except for women's-only items.

Primary use of this spectrum is for comparison, rather than figuring out absolute temp ratings.

Pocket dimensions

In addition to two hand warmers, Nano Air offers two external zippered chest pockets, whereas the DAS light offers one of them.

Pocket dimensions:

DAS Light:
- Hand warmers: 6.7 in (or 17 cm) x 9.1 in (or 23 cm)
- External zippered chest pocket: 7.5 in (or 19 cm) x 7.9 in (or 20 cm)
Nano Air:
- Hand warmers: 7.1 in (or 18 cm) x 11 in (or 28 cm)
- External zippered chest pockets: 7.9 in (or 20 cm) x 9.9 in (or 25 cm)

Nano Air wins.

Packability

Nano Air is packed into the external chest pocket and DAS Light into the left hand warmer.

Patagonia Nano Air vs DAS Light: Zipper pulls

Zipper pulls of each are pretty big. Packing and unpacking with the gloves is easy.

In the end, DAS Light is packed surprisingly smaller.

13" Macbook and sunglasses for scale.

Packed sizes:

DAS Light: 7.3 in (or 18.5 cm) x 6.5 in (or 16.5 cm) x 4.3 in (or 11 cm)
Nano Air: 7.5 in (or 19 cm) x 7.5 in (or 19 cm) x 4 in (or 10 cm)

A smaller packed size, however, can be a mixed blessing in this case. Size savings are of course always a plus. But packing the DAS Light is a bit difficult.

Stuffing the jacket into its sack (e.g the left hand warmer) is easy. The hard thing is to zip it without letting the jacket overflow and get in the way.

One way to do this on your own is to stick the sack between your legs to prevent it from overflowing. It's zipped rather easy that way.

Another factor to pay attention to here is after the zipping is complete. It feels like the jacket inside applies too much pressure to the sack.

Not sure what happens if it gets in contact with a sharp object, or if it gets stuck under larger, heavier objects (likely to happen when traveling).

I didn't experience any "burst" problems so far, but I don't have 100% peace of my mind yet. Will update if anything happens.

Another negative downside is after years of repeated packing and unpacking. When the compression stress is too high, a jacket might experience too much of a loss in insulation capability. This is normal after, say, 5 years of use, but when the stress is too much, it might be quicker.

After unpacking, however, the DAS Light restores to its original look quicker than Nano Air. Just shake it and you're ready to go. Nano Air is closer to a more standard outer fabric, so it looks a bit more crinkly.

Cuffs

Cuff designs are the same.

Hoods

DAS Light is better in this regard.

See DAS Light's drawcord design (left: hidden, right: exposed).

Nano Air doesn't allow for hood adjustment. It's a much simpler, standard hood.

Hem cinch cords

Strangely, DAS Light doesn't have a drawcord at the hem. Nano Air does.

History of Nano Air revisions

Changes for Fall 2019

Fall 2019 Nano Air.

Here's the summary of what I found:

Hemcord got replaced with a non-adjustable elastic. You could use the drawcord to adjust a more a snug fit to the hips when required - which now you can't do.
Durability and abrasion resistances seem to have improved.
It used to have 2 chest (not hand) pockets, now it has only 1.
Surface material is now smoother and feels somehow more pleasant in your hands.
The design changed: Horizontal lines through the front bottom are removed. It also looks more homogeneous now. We think it looks much better now and hence increased the style rating of the Nano Air as you can see in this post.

Here's what the representative told me first:

Fabric is now 87% recycled.
3-D texture which improves the next to skin feel and piling resistance.
FullRange Insulation is now 40% recycled.
Fabric is now Bluesign certified and Fair Trade certified.
Overall it is 10% lighter and more pack-able.

And how would one experience these technical differences when using? In terms of, for example; durability, warmth, weather resistance, breathability, comfort etc?

Here's what the rep told me about this:

"I think you'll definitely notice that this model is more durable - one of the things we get asked about all the time is the piling of our items. Piling comes with trying new recycled fabrics, so the fact this is 87% recycled and we're seeing reduced piling is really cool. The Nano Air Hoody also has 60 grams of insulation to keep you warm. It's very breathable, which makes it nice so you don't have to keep putting it on and off on days where the temperature is always changing or you're occasionally physically active.

I used to work at a grocery store, which was very labor intensive. One of my coworkers would wear his Nano Air Hoody everyday. He loved how warm it kept him in the morning but also cool enough to wear it all day even when he was doing heavy labor jobs (breathability). I'd ask him about it all the time because I'd be changing layers throughout the day, and was jealous that he never needed to do that. He had the light blue and even with the job he was doing, I didn't see any damage, or stains on the jacket. I believe that he had the 2017 season jacket but seeing it first hand how much even an older Nano Air could handle, I can only imagine how durable the 2019 season can be."

Obviously there's also at least a little bit of a marketing here - but I agree with everything she says except the durability part. Yes, durability did improve, but Nano Air is still a fragile, highly technical piece that wouldn't be able to handle a lot of damage.

If you'd like to look at something a little less breathable but with significantly more abrasion resistance and durability, I'd recommend checking out the Proton (aka LT).

Back to my convo with the rep...

She then told me that the hemcord got replaced with a non-adjustable elastic (after I asked her so... lol), and also the number of chest pockets got decreased from 2 to 1 of them (you can see this conversation in the screenshot below).

In the end...

These are the changes (same list in the introduction):

Hemcord got replaced with a non-adjustable elastic. You could use the drawcord to adjust a more a snug fit to the hips when required - which now you can't do.
Durability and abrasion resistances seem to have improved.
It used to have 2 chest (not hand) pockets, now it has only 1.

DWR stays the same.

What is DWR by the way?
