    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.

    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.

    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!

    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!

    Pretty good, but could be improved

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: Medium
    • Height: 5'9"
    • Weight: 160lbs

    I used this at three locations in very cold temps teens and twenties under a Gore Tex shell.

    It kept me warm, breaths surprisingly well, lets excess heat and moisture out. Exterior material seems very robust. The Proton AR has had no piling of exterior material whatsoever and it does not seem like the kind of material that would pile.

    Sizing, I'm 5'9", 32" waist, medium build. As others have mentioned, the arm pit area is a bit snug which is odd - but, I'm sure this jacket was specifically designed to fit under the more streamlined Arcteryx shells. Waist is snug and the waist adjustment is pointless if you're a 32 waist. Also the insulation is very fluffy so to speak, it's not a thin insulation, the jacket does hang on you, it sort of sticks to you. I'd prefer slightly longer hem and a hair looser overall especially the pits (or put Proton LT matl under the pits).

    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.
