Customer Reviews Arc'teryx Proton Hoody

Similar to my 10 year old Atom LT, except this revised Proton Hoody is a little bit longer from front and backside which is why I bought it. Arms are perfect length and the cuffs are great. Pockets are nice, hand pockets are a little higher than on old Atom LT I think. They have fleece lining on front inner side. Only con is that the hood is a little wide which is meant for helmets and stuff I guess. Who even uses this stuff. Just make it normal. I'd rate the jacket perfect if the hood was normal. It's still great jacket. About sizing: My old Atom LT is Large and on this revised Proton Hoody it's same as Medium. So the sizing has been changed and I recommend to take 1 size smaller. I'm 183cm tall and 80kg in good shape, wide shoulders and the Large Proton that I bought was like Atom LT in XL, so I had to swap to Proton Hoody Medium size.

Love this jacket! Used for climbing, hiking and everyday use. Great all round product.

Seems like a lot of complaining about the new fit. I personally find it spot on. Of course all clothing will have reviews that complain of fit but I'm a bit surprised by some of these for Arc product specifically. The longer sleeve length is a hallmark of their jackets. They've maintained that with the new pattern and its perfect combined with the simple cuff and articulation of the shoulder and armpit. The sleeves are just slightly longer than my 15 year old Atom LT if that's a useful reference. And they are definitely not baggy. No idea where that complaint is coming from. I'm a very 'average' build 6' flat, 185 lbs 'evenly distributed'. The drape (or hand or whatever you call it) of this fabric is also really cool. It's butter soft and moves freely over your baselayers (seemingly without creating a bunch of static. I could be full of it regarding that feature but it seems that way especially compared to the more 'felted' interior of a grid face fabric jacket I wear casually or even compared with my Atom LT though its made more of type A than its original face fabric at this point. Build quality: You know this already but really look at the stitching next time you buy something from Arc. The thread spacing, the parallel stitching...there are no unrulily edges or untucked seam allowances. The quality is just friggin high compared to a lot of the crap out there.

I love the this jacket! The updated fit in 2024 is perfect. This is my go-to jacket for many activities. I use it both as a active insulation mid-layer and a stand-alone jacket. Good warmth and breathability. Love the discrete stitched bird logo on the chest. Dont like the ArcTeryx word logo on the hood, less is more. Love the Tatsu and the Black colors with no contrasting chest color. Would love to see more colors in the future.

Arcteryx certainly has made the shift from a trimmer leaning proportions to 'more generously' sized ones. This regular Proton feels the same if not slightly lighter in fill power than the Atom and is definitley more relaxed fit than the trimmer fit they had in the past. Im 200 and 5'9 and I have ample space to layer underneath.

I have always thought of Arc'teryx as clothing for the name brand. But after recently having the opportunity to grab the proton hoody my entire perspective changed! I think the quality and materials fit exactly the description and activities I get up to. I really like the embroidered touches too. Im 6'8 and got the 2xl which amazes me of how well it fits with arm length vs torso length. The hoody cinch has been the biggest surprise! It actually works and snugs the face well without overhanging into your eyes if you choose not to wear a hat/helmet underneath. Super lightweight, and the breathability vs warmth is surprisingly really good. Been raving about it to a lot of my mates so I am stoked

Got this in Heritage and love the color. Fits perfect as a midlayer, not too loose or snug. Very comfortable. Sleeves work fine for me. Not as warm as down when standing still, but very good while active. Very pleased with purchase.

Another great jacket. No complaints. Appreciate the logo being stitched now as my old one is falling off.

The proton jacket is a fantastic piece of gear! However, the fit could be improved. The medium size works well for me, but the armpits and arm lengths feel a bit tight. The large size fits the arms nicely, but it feels like a tent on my body. If you're an average build European man, you might also find this to be an issue. Other major mountaineer brands don't have this issue..

The jacket isn't cheap, and with shipping it cost me a fortune. I had high expectations, but reality was quite different. It's breathability is very good: at temperature of +2C and light damp wind (7-10m/s) one feels very uncomfortable with base layer (Icebreacker Anatomica merino t-shirt) + fleece (Fjallraven Keb Hoody) under the jacket. And it was just a regular walk. Same with water resistance: after 1.5 hours of walking in drizzling rain in almost identical layers (merino base layer + Patagonia fleece ) I was soaking wet (jacket, fleece and t-shirt). Now I don't really know when to use it without shell layer - only on sunny, windless days? According to fit: jacket fits me great (size M with my 176cm (5'7") height and 100cm (40") chest. I think internal pockets would help this jacket, as would a little more wind and water resistance. Would I recommend this jacket? Well, that depends...

Lightweight outer insulation for cool days or while moving in cold weather. As a mid layer in cold weather. Climbing or hiking. One negative- sizing. If you plan to use as a mid layer you may have to size down to avoid bulk and maximize warmth. The medium is a large on me. 5,8 160lb.

Reviews said this has a roomier fit than previous models. That seemed to be true because the arms on my older Atom jackets were too snug, but the XL fit was perfect otherwise. This jacket fits me like it was tailored for me, and the color is awesome (I have the Cronin pants in carob too, which is nice).Im 510 muscular 220lbs. My shoulders/chest are wide, arms are thicker than normal. Happy to find something that fits and doesnt look baggy.

This is the most comfortable synthetic puffy I have ever worn. The material feels nice on the skin unlike the Nano Puff or other synthetic puffys. It has nice stretchy cuffs and a good zipper. It has been my favorite synthetic puffy for the last 8 years and thankfully Arc'teryx hasn't really changed it since.

I have the lightweight version of this jacket and its absolutely terrible. Whenever I wear it the bottom half of the jacket always rotates to the right. Even during a walk around the neighborhood the bottom of the jackets twist. Im very disappointed with this jacket and would not recommend it.

The Proton has quickly become one of my favorite jackets from Arc'teryx. In some ways, the proton feels like a higher end version of the classic Atom jacket (which I love and is still one of my favorites). The material on the proton feels softer than the atom and provides really nice next to skin comfort. It also feels as though it has a little more stretch to it which has been great for climbing. It fits under a harness quite comfortably as well and doesnt pull up when reaching over head. The back side of the jacket hangs a littler lower too which i have found to be nice when wearing a harness. It fits a littler larger than other comparable jackets from Arc but it allows me to layer really comfortably with a fleece underneath like the delta. The proton seems to have a perfect blend of breathability and warmth without much compromise on either end. One seemingly underrated aspect of this jacket is the wrist cuffs. They did a great job adding a wide elastic band in the wrists which tapers well and allows you to slide up the sleeves easily but still creates a good seal at the wrists. The hood also fits well with a helmet on. Lastly, I've been really impressed with the durability of this jacket. I wore it everyday for a week while teaching a climbing course down in Joshua Tree and have zero pulled threads, holes, etc... The terrain down there can be quite unfriendly to clothing but the proton held up just fine. Great work with this garment! For reference, I'm 5'8 145lbs and the small fits very well.

I primarily wear my Proton when I know that I'm going to have an active day, whether that means running errands around the city or doing cold-weather hiking in the Rockies. Since the Proton is temperature regulating, I know that I can wear it and feel warm without getting overheated. For this reason, it's also great on crisp days when the weather is starting to cool down - I wear it everyday in the fall. It fits very well, just as expected. Super versatile jacket that can be enjoyed in any situation!

Updated design is definitely slightly bagger than my previous 2022 proton jacket with material feeling slightly thinner, not sure if that is because of the insulation switch between the models. Overall, I am still happy with the product, but I wish they would stop making sizing changes.

Comfy in colder or warmer weather, feels great on the skin!

This has been my go jacket for most of my activities in colder weather. This jacket is always the first thing I pack when traveling for hiking and climbing adventures. The jacket breathes well while exerting yourself. Sweat moves through the jacket and evaporates quickly. It provides plenty of warmth even when wet. It remains remarkably warm while static, and I'll usually pair it with my Squamish Hoody or a hard shell jacket when the wind is really blowing or its extra cold. The cuffs are really unique and keeps the sleeves in place. The pockets sit high enough to still access with a harness on and the chest pocket comes in handy for quick access to maps, hand warmers, and anything I might need access to in a pinch. The hood can fit well over or under a climbing helmet and does a great job of cinching down to keep cold air from creeping in. The only thing I would change about this jacket would be a slightly longer bottom hem. I have never had an issue with it coming out from under my climbing harness, but an inch or two would be ideal for me and my body type. I got a medium sized jacket and it fits a bit snug, but a large is too baggy for me. It still does not restrict movement and doesn't interfere with climbing. Overall I have really enjoyed this jacket and it is a great all around jacket for most of my adventures. It has shown no signs of wear and tear despite the many miles and pitches I have put it through. It'll continue to to be my go to jackets for years to come. One of the best pieces of gear Arc'teryx makes in my opinion.

So far so good Like wearing a warm cloud! Light, warm, cozy Satisfied

Great shoulder-season jacket. Used for hiking, bike commute and throwing on when I need a bit more warmth than a hoody. Yes it's expensive but I recently packed it in my carry on for a trip to Europe; it packs down really small, it's very light weight and it was perfect for this time of year (Sept/Oct). It provides minimal water resistance but I got caught in a few rain showers and it held up fine. Overall very happy with it so far. Dropped one star for 'value' rating. If I get more use of it through the winter months then I'll revise it up to 5 stars.

Most comfortable daily wear jacket I have. It's soft, warm, and breathable. I bought it to wear under a shell for skiing, but have not had a chance to use it for that use case. In the meantime, I wear it almost everyday, when I expected to just keep it in my closet until ski season. The fit isn't as flattering as my other Arcteryx stuff. Not sure if it's because of the puffiness, but I wear it a lot in spite of that. I do wish they made a non-hoody version. I tried the Atom, but the Proton is superior in terms of insulation and feel.

There is nothing revised about this Proton at all. Its the same 2019 product just more expensive. Second, I live in Florida and only use this Jacket during the winter when traveling north for work. Ive maybe worn it a total of 8 times in 10 months. The logos which are smaller are already falling off or are totally faded. This is not the case with my 2019 jacket. Dont buy.

I wear it when hiking, it is very comfortable and soft, love the design and color of this jacket
