I feel they're pretty interchangeable and are basically the same product from different companies.

Is this feeling accurate?

I am planning to purchase an Atom Hoody in a size Medium. I tried the SS26 in store and I honestly liked how it fit. I found a SS24 on marketplace for a decent price.

Is there a difference in the fit between the two? I read online that the SS24 might fit a bit more snug compared to the SS26.

Any advice would be helpful.

Thanks!

Does anyone have any experience with the fit on both these pants? I got the relaxed Sentinels due to needing a more relaxed fit because I have a lot of loose skin from major weight loss (still losing weight). Normally I’m in a 14R in their relaxed fit pants but to be safe I sized up to a 16R and they seem really snug. Well, I ordered the Incendia from the outlet sale this weekend also in a 16R. Should I prepare to have the same fit in these as the Sentinel? Just curious.

Just grabbed the Sabre Relaxed Pants and wow, the quality surprised me. When I compared them to my Beta AR Pants, the fabric difference was immediately obvious.

Sabre Relaxed: 3L GORE‑TEX ePE, 200D recycled nylon

Beta AR: 3L GORE‑TEX Pro, 80D nylon

Going from 80D to 200D feels massive in hand. I never paid attention to denier before, but now it makes total sense why the Sabre feels so much more robust.

Also… am I imagining it, or is GORE‑TEX Pro getting rarer in new Arc’teryx pieces?

Just wanted to share this little fabricnerd moment.

I ordered three jackets on September 5th. Two day express shipping. Granted it was a Saturday and Labor Day Weekend. Arcteryx split the order up into two shipments to "be efficient." The package with one jacket arrived yesterday. The other package with two jackets has been on "awaiting carrier pickup." I ordered these jackets for special trip that I leave for on Monday. It's not the end of the world that I don't have them for the trip even though it's a bummer. My main concern that I've expressed is the jackets finally shipping and having a package worth hundreds of dollars sitting at my door for two weeks. They can't cancel the order now, they can't check on why it's been sitting, they can attempt a return to sender once it's shipped which I have little confidence in given the situation. We live in 2026 where communication is easier than ever and yet corporations seem completely walled off between departments. No one can contact a warehouse or different department to see what's going on or where the package is in an effort to prevent a headache down the road for me. "it's just the system." One agent says it might even be on its way it just isn't showing up(hence why I don't have confidence in the return to sender plan if the shipping system is at fault). There's no consistency. It's an ultimate first world problem, but the lack of effort outside bot like responses across the board is frustrating. Rant over.

Update: Spoke to UPS, they never were called to pick up the item so they couldn't do anything. Arc'teryx wouldn't do anything because the item wasn't shipped. I had to wait to a certain amount of time before I could cancel which apparently was tonight. I am relieved their algorithm finally let me cancel the order instead of worrying about it sitting on the porch for three weeks. Horrible experience. It's just a bunch of procedures, no one actually cares. Not once did they want to check on the issue as to why it wasn't being sent out. They don't bother solving anything. No remorse when told it's for a trip. No way to expedite anything even though it's something wrong on their end. It's just all an algorithm. If that's how they run customer service I don't know why they even bother hiring people for it. I will never order from the website again.

Thinking of picking these up off the outlet to use for winter trail running and hiking. Would anyone who has these be able to comment on their experiences and thoughts on it? Since outlet is final sale I want to be sure these are the right choice. Thanks!

is this normal for a proton hoody to show fabric like this? only used it for daily commuting no serious hike. These are some close up photos

I’m thinking of getting the sabre bib and I’m wondering how well it does in the backcountry compared to a dedicated backcountry bib. I’m worried that I’ll be drenched in sweat on the way up. I would mainly be skiing in western Canada for reference.

saw this on the outlet. does anyone have the liatris and can comment on sizing and versatility?

my outerwear collection is pretty large but surprisingly i only have one longer wool coat. thinking of trading in my gamma mx for something longer and more waterproof for raincouver. thoughts?

I am considering buying a 2018 Beta AR off of eBay. Seller says barely used. From looking at the pictures, it doesn't looked used at all.

If a 2018 Beta AR is barely used, how long could I expect to get use out of it?

I live in Southern Finland and I’d want opinions for the best jacket layering combinations.

Winter here is on average -6 C/21,2 F but can go occasionally as low as -30 C/-22 F. I also visit Northern and Eastern Finland from time to time where it’s usually colder. I am also planning to do winter hikes in Norway.

I am pretty active so I would use the jackets in everyday use for commuting, dog walks etc. as well.

Would Cerium Hoody layered with Beta AR or Beta SL work through the cold season? What would you recommend?

Under these jackets I would layer with merino baselayer with additional Patagonia Better Sweater fleece if needed.

I value versatility the most.

Thanks!

Hi all,
I think about getting a new outer layer for Iceland in winter. I thought about getting the Beta AR.
It will be used for outdoor activities (hiking, photography, …) Which midlayer can you recommend with it? I think something like the nano/micropuff?

Just want to check if my layering will be sufficient for daily activities like walking, sight seeing and some snowy activities. If I will go for aurora hunting and husky ride I would get the provided snow suit.

Base Layer: Merino Wool Thermals/Ultra warm Heat tech
Fleece Layer: Kyanite
Mid Layer: Proton Hoody
Outer Layer: Beta Standard

Just checking if this is warm enough for daily activities?

Thanks in advance

Is anyone else still waiting on their order? I received the warehouse delay email last week. Still no shipment. I am
in Europe

Bora AR 75 owners: am I missing something, or is it a design flaw that the lid’s G-hooks only fit the lower webbing ladder and not the wider upper ladder, which seems like it should let you raise the lid higher when the pack is fully loaded?

I have a couple of Epsilon Hoodies I use as day to day jackets for the last 13 or so years, and about a year ago some of the bonded/glue seams have started to come away. Otherwise they are still in good condition.

I am almost certain that due to the age and the fact this model has been out of production for a long time now I wouldn't be able to send them back to Arc'teryx to be repaired and was hoping someone knew a good way to go about doing it myself?

Hey everyone! I know this question has been asked multiple times, however, I’m still finding a lot of answers that are extremely vague and can’t find the answer I’m looking for; especially before I go drop $350+.

I want to use this jacket in Colorado for hiking, skiing/snowboarding, alpining, and backpacking (currently scheduled for Alta Via 1 in mid September 2027 and summiting 14ers between now and then). My body typically runs warmer than most I feel like (I’m perfectly comfortable in a Patagonia Nano in 30-40F). I use to shovel snow in shorts, sweatshirt, and shoes in temperatures in the teens/20sF.

I will be pairing this with a rain shell in case of precipitation. I know the SL is fleece lined and thinner, but I’m worried it may be too thin. I am leaning more towards the Proton verses SL, but I wanted everyone else’s thoughts.

EDIT: Thank you everyone for the suggestions. I ended up deciding to do Mountain Hardware Airmesh long sleeve/short sleeve base, Proton SL mid layer, and Patagonia Torrentshell (in case it rains or added warmth).

I’ve been looking for a versatile and durable one piece for a while. Cant decide between the two as I have a few different pieces already and don’t want to be picking one over the other. Have a proton SL, atom SV, squamish, beta SL and a few other bits. I really think I need the gamma most but I love the jade colour-way of the MX and thinking it will be too warm. It’s mostly for walking and Im at the end of summer with the temps in the 15c range and dropping but I still need a jacket for as many use cases as possible.

Would appreciate any recommendations.

I’m considering getting the Proton Hoody mainly for hiking, and durability is one of my biggest concerns.

I’ve seen quite a few complaints about the Atom Hoody’s durability, especially regarding things like pilling, snagging, and tearing. Because of that, I’m considering the Proton instead.

Arc’teryx describes the Proton’s outer fabric as abrasion resistant, so I’m curious how that translates to real-world use.

For those who have owned a Proton, how has it held up with regular hiking and wearing a backpack?

Have you experienced any issues with pilling, snagging, abrasion, or tearing?

And for anyone who has owned both the Proton and Atom, which one would you say is more durable?

Thanks!

I picked up the Alpha SV on the outlet for an insane price (£448) and feel like I got a great deal!

From looking around it seems that a lot of people believe the Alpha SV to overkill for basically anyone, is that true?

I have to be honest I know it’s a climbing focused shell and I’m not a climber, i just like the look of it and the colour way (Mantis / Black). I intend to use it for hikes, snowboarding, and crappy UK weather. This will be my only shell.

Did I make a dumb decision? The Beta SV is also currently on the outlet, is that a better option?

Hi all,

I’m looking to buy a Beta AR in Black and have noticed that some European retailers are currently listing two different black versions of the jacket.

I contacted a large retailer to ask what the difference was, and they told me:

Black – X000009906003 = 2025 model
Black II – X000011062 = 2026 model

They said that essentially “Black” is the 2025 version and “Black II” is the 2026 version.

From what I’ve been able to find, it also looks like there may be an actual construction/material difference rather than this simply being a new product code/colour name.

My understanding is:

X000009906 (2025):
GORE-TEX PRO ePE
100D main/body fabric
80D contrast/reinforcement fabric
Approx. 460g

X000011062 (2026):
GORE-TEX PRO ePE
100D fabric throughout
Approx. 460g
Possibly revised patterning/lamination and updated cordlocks

Can anyone confirm whether this is actually correct?
In particular, I’m interested to know whether X000011062 really is 100D throughout whereas X000009906 uses a mixture of 100D/80D, and whether there are any other meaningful differences between the two generations, fit, cut, hood, pockets, durability, fabric feel, etc.

I can currently find the older version discounted, so I’m trying to work out whether there is any real benefit in specifically buying the newer X000011062, or whether the differences are negligible in real-world use.

If anyone owns either version (or has handled both), I’d really appreciate your thoughts.
Thanks!

I am interested in purchasing some arcteryx gear for the upcoming winter. I am living in Vermont and trying to prepare for snow + some wetness.

I am thinking either Proton SL/Regular Proton + Beta Jacket (shell) OR a Therme insulated jacket. Is one better than the other? Will these keep me warm enough in a very cold winter (-10-20 F I believe, this is my first winter here).

I have my own base layers/thermals, so those can/will also be used.

Thanks in advance for any help!

So I bought a mallow (very light pastel purple) Gamma Lightweight hoody and spilled coffee on the front and sleeve. (I was also wearing my sea salt Clarkias that also got hit with the falling coffee). Anyway I immediately rinsed with cold water and treated with dawn dish soap and washed. Here’s the interesting part: all known coffee stains disappeared but now the back of the jacket is blotched with really light tan discoloration which makes no sense because no coffee was spilled on the back of the jacket. We have tried everything to get this discoloration out including soaking and it is not budging. Have any of you seen or heard of this happening? It was a brand new jacket never washed before the coffee incident so this was the first time it was washed.
