Arc'teryx  Proton Insulated Hoody - Men's

I cannot recommend this due to the low quality of the outer fabric. My unit started pilling on the lower outer hem after only 7 weeks. This is an area that receives zero friction (I don't use backpacks or drive), yet the material is failing on its own. Arc'teryx considers this "normal wear" for the Proton series. If you are looking for technical gear that lasts, look elsewhere. This fabric is too fragile for even gentle daily use.

Bought this for use as a mid-layer at the end of Jan this year. Loving the fit and breathability of the jacket. Keeps me warm under a GoreTex shell even in -20C, but doesn’t get too hot when things warm up. I’m quite disappointed however, that I’ve had this for one month and the jacket is already showing signs of wear and the material is pilling under the armpits. I’m using it for resort skiing and as a light jacket around town, and not using a backpack. Kind of blown away that a jacket at this price point is showing this kind of wear with a month of light use.

There is nothing revised about this Proton at all. It’s 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. I’ve 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. Don’t buy.

I used to hike in an Atom until I discovered how much more breathable the Proton jacket is. I often struggle getting too hot, even in cooler conditions as I'm a very sweaty person. I hike in this for most winter hikes and don't find myself overheating. It's also incredibly packable and I love the colour too. I have one in navy blue and bright yellow too.

I’m an avid climber and this garment is my go to piece for my outdoor exploits. Warmth without bulk, range of movement without constriction… whether I’m in the high alpine or at the fall, winter, or spring crag, this piece provides me with the protection/ warmth that helps me complete the send. It is truly perfect!

Great warmth to weight ratio fits well and looks good. Unfortunately, after just a few months of wear around town the nylon shell ripped. I'm not exactly sure how it ripped but it was not through any misuse or improper care. I've been an Arc'teryx fan for many years but this is just one of several products I have bought in the last year that are nowhere near as durable as my older products. The products I have that are older than 5 years are in better shape than the those I have bought in the last year.

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

I've been using a Proton the last 4 months for winter season and travel. I've used it from 20° up to 70°f and have felt comfortable thanks to the superb breathability. It's not the most wind resistant - a cold breeze can still sneak through - but its a tradeoff that works. The Proton is meant to be an active piece. The jacket is still plenty warm, and when I'm hiking, the breathability is a big plus as opposed to feeling like I'm in an oven. I took this jacket on a 3 day motorbike trip in the north of Vietnam (ha giang loop) and the wind resistance worked great. The jacket itself feels durable and the fit lends itself towards slender, athletic people (it fits my 6ft frame flawlessly). I love the articulation and quality of the pockets and cinchcords - everything is top notch. My favorite aspect of the jacket though is the insulation. You get this wonderful burst of warmth the moment you put it on. The lining is buttery soft and it's the perfect jacket for those frigid mornings you need to step out of your tent for hike to the restroom.

Arcteryx has completely abandoned its quality control measures. I have over 10 pcs (atom, proton, beta lt, beta ar, atom vest, cerium jacket, fleece sweaters, etc.. and ALL of them are in size M (I'm 5'11, 170lbs). My sister (who lives in the US) bought this for me since she knows I wear size M and sent it over as a present so I can't even return it. This thing fits horrendously, it's like wearing a big garbage bag, the sleeves are unrealistically long and wide, the torso is huge (like a plus-sized jacket) while the neck, hoodie and back length are the same. the old proton used to have a more sleek fit which was easy to layer under the shells but i can't imagine layering this one under any shell comfortably. The old proton fitted like a proper, fitted mid layer but this fits like an oversized parka. I've been reading a lot of reviews about Arcteryx messing up their fits on most jackets and witnessed it firsthand today, will be avoiding their new collections and "revised" fits from now on. it's sad to see such a good brand that I love go down the drain.

I received this as a gift from a client of mine, and I am very happy with how it’s lasted me for the past 2 years. It’s survived New England (Massachusetts) weather pretty well, and does great in the snow and rain. I took away one star because I would have liked to have pockets on the inside of the jacket, but the fit is great (5’10”, 180lbs, L). It’s light and keeps me warm. Minus one star since the DWR has basically worn off, and isn’t what it used to be, so it looks soggy when wet. Pairs well with an Arc’teryx gaiter! Especially with the matching color and logo.
