    Details

    The essential element.

    Putting the proverbial handle on wet weather, wind, and all-around cold temps, the Arc'teryx Men's Proton AR Hooded Insulated Jacket is the one layer you won't want to leave behind the next time you venture into the alpine. Arc'teryx designed the Proton to function as a softshell when wind and light precip catches you hiking down from the summit or belaying three pitches up a route in the alpine. Being the warmest offering in the Proton line, the AR Hoodie is packed full with 90g Coreloft���insulation composed of crimped synthetic fibers that are breathable, compressible, and water-resistant���to deliver dependable warmth in demanding mountain environments. Never one to phone-in fit, Arc'teryx made sure the fit of this jacket promotes mobility and stretch while limiting needless bulk (and weight) when every ounce counts.

    Under the Sun

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 5'9"
    • Weight: 194lbs

    Been using this jacket for any kind of hiking or winter holiday, even under the sun, my body didn't feel too hot (surely breathable), I remember my first time hiking the same mountain with cheap jacket (felt super sweaty and hot). As a result, I love this product very much.



    My winter holiday to japan, most of my family members used 3-5 layers to heat up their body meanwhile I only used 1 t-shirt and 1 arcteryx proton AR jacket. Superb result!



    No faulty so far, very recommended.

    Warm and Breathable

    • Height: 6'0"
    • Weight: 165lbs

    I picked up this jacket mainly because I'm a jacket hoarder and love Arcteryx. I have an Atom AR, Cerium LT, Iser, and Atom SL. Did i need this jacket? No. But I am glad i have it. Its a great mid-layer and the warmth to breathability is top notch.

    First Arcteryx

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 6'0"
    • Weight: 150lbs

    Got a different Arcteryx jacket first and didn't like the athletic cut on the small so bumped up to a medium for this guy and it fits perfect for my size. feels really nice and is an awesome jacket. Really warm as well, I was surprised about that. Synthetic insulation is getting better every year. the only thing that seems odd is that there are a few loose strands of stitching in places, I just trim them with scissors and it's all good but would expect a little more precision from Arcteryx.

    My favorite insulation

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 6'0"
    • Weight: 165lbs

    Over the past year the Proton AR has become my favorite insulation. It's as warm as my high-pile fleece, if that gives you some reference. Surprisingly, it also breathes nearly as well as that fleece, yet when I'm sweating hard under a shell, I don't get nearly as much condensation inside the Proton as I would with that fleece. Despite this breathability, I've never noticed wind getting through.

    One quirk is that the waist is cut pretty snug. I tried on both the medium and large, and even as skinny as I am (6'0" and 165), I almost got the large just for a little slack. I don't know if Arc'teryx has changed this with the current model, so you might want to try both.
    Also, a note for the more fastidious out there: I've read gripes that the CoreLoft occasionally comes through the fabric, like goose down will. I've found the same pinch-and-pull technique gets the CoreLoft back where it should be. Knowing this, I would still buy the Proton without hesitation.

    I just got the medium, and have not found it to be snug at hips at all. It feels looser than last years Proton Lt, I'm thinking they've adjusted their sizing proportions in the newer model. I'm 5'8, 175, athletic build and usually have a hard time fitting my upper back and shoulders but the sizing on the Proton Ar was perfect for me!

    Great Jacket

    • Familiarity: I've used it several times
    • Fit: True to size
    • Height: 6'3"
    • Weight: 225lbs

    I own the Nuclei FL jacket and was very impressed by the warmth Coreloft provides in such a light garment so I upgraded to a more durable model like this one. Really like it. Two hand and two chest pockets, a hood and still super light with the added benefit of wind and weather resistance. Only glaring drawback is when you put stuff in the pockets of any bulk you have two choices for the zipper: zipped all the way and unzipped. Anywhere in between and as soon as you take a breath the jacket unzips itself. The main jacket zipper is very thin and tiny and the teeth provide no resistance for staying in place. Not sure if this actually a defect or by design. My Nuclei jacket does not do this. Makes the pockets semi-useless for gloves and other bulkier items.

    Rock Solid Midlayer

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: XL
    • Height: 5'11"
    • Weight: 200lbs

    Very Solid Jacket for Mountain Alpine Cold Weather, great protection in the chest, arms are well insulated very flexible even when adding a shell. I use it with a Beta AR Shell and they are great together just enough room in the Proton for myself 5'11 200 lbs. says semi fitted does not seem like it because it fits my older not fitted body. I would recommend and it will be durable not really meant for a around town layer it like abrasion!

    Perfect "All Round" Softshell/ Midlayer

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Large
    • Height: 6'1"
    • Weight: 160lbs

    The Arcteryx Proton AR is the perfect blend between a durable softshell and a warm breathable synthetic midlayer. I use this jacket for practically everything, from skiing, hiking and running around town to climbing walls on the wasatch. If your thinking about a mid layer from arcteryx and you want something a little warmer and more durable then the ever popular Atom LT get the Proton AR you'll be glad you did.

    Do you have any reservations regarding the overall length of the jacket? I am 6'1" and when trying on the medium-sized model I found out that when I raised my arms half of my stomach got exposed. Did you experience a similar thing while wearing the large model?

    a better atom

    • Size Bought: medium
    • Height: 6'0"
    • Weight: 185lbs

    This jacket is hands down the best touring midlayer i have ever used. Before that my go to would be the Atom but ever since our Arc rep stephen mentioned this had some tech built in making its warmth to breathability even better then the atom i was sold. The crimped material not only breathes better but also packs down a lot smaller. If you are looking for a step up from the atom with more technical ratings this is the piece. Although i use this for touring its built for climbing so fits accordingly. I got the medium and i should have gotten the large (6 foot 185lbs). My job is to make those mistakes so if you are in between sizes give me a call to chat about it or discuss any layer questions. My contact info is listed below!

    LOVE THIS JACKET!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'8"
    • Weight: 160lbs

    Bought this jacket because I needed something that would be suitable for AT skiing that was trim and not too bulky and was also warm and packable. This jacket delivers on all counts! I have also used it ice climbing and its athletic fit makes it possible to actually see your feet and harness! Withstood a lengthy bushwack without fail also!

    Good all around jacket!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'1"
    • Weight: 190lbs

    I bought this jacket because i needed something for day to day use with good insulation and I'm very stoked on my purchase. This jacket is great! Holds up to the cold weather out here in Utah! It also is a great jacket to layer up with! Merino wool baselayer, this jacket and a 2.5 goretex shell in 10 degrees with the snow dumping and I was still breaking a sweat!! Can't wait to use this jacket in the spring while climbing!

    Great Softshell

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: large
    • Height: 5'11"
    • Weight: 200lbs

    Great jacket. Just bought it. It is like a hybrid of an Atom LT, a Patagonia Nano Air, and a softshell. It breathes better than the Atom. I won't go so far as to say it breathes better than the Nano Air, but it is close. It has been a great jacket for 20-30 degree days. The Proton AR also layers easily under a shell (for me a Beta AR and Theta AR). The jacket is great for hiking and great for around town use. It is an athletic fit. So, if you are buff or have a gut, then you may want to buy a size up. I am 200 lbs and muscular, so, the large fits well.

    Arc'teryx – Men's Proton AR Hoody

    An all-round, versatile hooded jacket created to balance warmth and airflow, the Proton AR Hoody is the warmest option in the Proton series. Designed to perform both as a softshell outer layer and as a mid-layer under a waterproof shell, it leverages advanced material technologies that provide thermal protection while allowing air to pass freely in and out. This helps prevent vapour accumulation and allows the Proton AR to regulate comfort over a wide range of temperatures and conditions.
