    Proton LT Hooded Insulated Jacket

    While carrying a jacket for every kind of weather you might encounter may appeal to your inner gear geek, it's a whole lot easier to carry one layer that will handle just about any inclement weather you face in the high mountains. The Arc'teryx Men's Proton LT Hooded Insulated Jacket puts versatility at the top of its strengths with a breathable and weather-resistant softshell face and water-resistant Coreloft synthetic insulation. Arc'teryx's Fortius Air 40 fabric is air permeable to prevent overheating while you're on the move, but resistant to wind, water, and snow when clouds gather over your objective. Coreloft insulation adds lightweight warmth that is quick to dry, whether it gets wet with sweat or snow. Arc'teryx gave the Proton a climbing-specific design with a trim fit to reduce needless bulk, articulated arms and gusseted elbows for climbing mobility, and a hood that fits comfortably over a climbing helmet.
    • An insulating layer adept at climbing rock, ice, and alpine granite

    Light and breathable piece

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Height: 5'11"
    • Weight: 170lbs

    Great midweight/light jacket. Used it as layer while hiking Aconcagua. Incredibly light and pack able. Fabric is not as durable as there gortec shells but breathes much better. When not using it as a layer for hiking I use it when the weather is a chilly but not cold.

    Super technical piece, not for me

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: XL
    • Height: 5'10"
    • Weight: 180lbs

    Don't get me wrong--its Arcteryx so you know it's going to be quality. At 5'10 180 though I ended up having to size up to XL because the L was too tight in the torso. Amazing jacket I just wish it fit me better

    Great Versatile Jacket

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Small
    • Height: 5'3"
    • Weight: 150lbs

    The proton is a great technical mid, or outerlayer in colder weather and it's breathability goes a long way to limit the sweat factor. On top of that, it is a great stand alone spring or fall weather jacket, and while it is a technical jacket, it looks good and normal enough to wear around town or to dinner. I got a small for a more technical fit and layering options. Even though it is a tighter fit, the small amount of stretch and the materials used ensure it is still comfortable and not restrictive feeling.

    Proton plus Atom

      I felt guilty hitting the buy button having already owning an Atom lt. I was wrong, they are different jackets and have strengths compared to the other. The proton is a warmer coat than the atom but the overlap in all of the right places. I think proton slogging down hill and atom uphill. Have one or the other or better with both.

      I'm wearing it while writing this!

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Medium
      • Height: 5'10"
      • Weight: 135lbs

      I absolutely love this jacket! I've taken it as a mid layer on a snowboarding tour, around town, and on dates! It really does work for whatever you want it to. It's incredibly breathable, but still incredibly warm. When I was winter hiking in this, I had to unzip it and let some cold air in from time to time. When moving around, this jacket is just too freaking warm! Good problems ;)

      I got this jacket in a Medium, just because I wanted it to fit a bit looser. I know Arc'teryx makes their stuff fit really well, and if I wanted it to fit my frame, I would have definitely gotten a small. But I wanted a bit more of a loose fit with this jacket, so Medium fits well enough for me!

      Warm and Lightweight

      • Familiarity: I've used it several times
      • Fit: Runs small
      • Size Bought: Women's Medium
      • Height: 5'4"
      • Weight: 125lbs

      This is the perfect puffy for wanting warmth without the bulk. Arc'teryx is known for running a little small, so that's something to consider. I like how sleek this jacket looks. You get the warmth of other synthetic insulated puffy jackets, but it doesn't look like you're wearing a sleeping bag. The DWR treatment is great if you get caught in a light drizzle. Also, getting the hooded version is definitely worth it for extra warmth/coverage from the rain and snow. Definitely would recommend this jacket for lightweight warmth and breathabilty!

      Very nice jacket

      • Familiarity: I returned this product before using it
      • Fit: Runs small
      • Size Bought: LArge
      • Height: 5'10"
      • Weight: 185lbs

      I think this mid layer jacket would be great. Comfortable and warm yet breathable. I returned as I liked the fit of the Atom LT a little better. The Proton was snug in the chest and arms. But it moved freely. I liked the slightly looser feel of the Atom LT.

      Amazing

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Large
      • Height: 6'2"
      • Weight: 240lbs

      The first jacket that taught me how to love.
      I'm not joking, this has been one of the best things that have happened to me. When I look back at 2018 I will shed a tear of joy, not for the amazing experiences I had traveling the country, not for the release of yet three more amazing Marvel movies that have shown me that it there hope in the world.
      No, it won't be for these things. I will shed a tear thinking for a moment about the day I met the Arcteryx Proton LT jacket and it held me. The moment I was swaddled in its armholes I knew that our relationship would be greater than any man/jacket love story yet to be told.
      Someday when I die and have to say goodbye to this jacket for the last time (because it should last that long with its lifetime warranty) I will die a happy, man. For I had the privilege of meeting the Proton LT jacket in this lifetime

      By this jacket, I give my witness that it is worth it. How much would you pay for a great friend that is always there when you need it? Well, personally folks I think $299 is just a small price to pay for such a gift.
      And to those who end up passing this review thinking, I am just a wack job who spent way too much time writing a review on a product on a random website. I say to you, i'm going to be the one laughing when you are out in the cold trying to get the loft back in your jacket and trying to survive the cold. Good luck to you poor soul, remember that Arcteryx will always accept you back into its open arms(holes).

      Sincerely,
      A simple man, with an amazing jacket

      Jack of all alpine trades

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: XL
      • Height: 6'2"
      • Weight: 215lbs

      This jacket is your go to for versatility on any alpine pursuit. Whether you are on the rock or ice wall, this has the sleeve length necessary to do it all. I use it skiing and love the breathability that comes with this piece. At 14 oz, it is the ultimate LT (lightweight) option and will always do its job. With "Arc'teryx fortius air 40" that is a dominantly nylon construction- you will find it to be very mobile and waterproof with its DWR coating. Very compatible with harness wear, and a sleek jacket for really any occasion with its minimalistic appeal.

      Very Impressive Technical Jacket

      • Familiarity: I returned this product before using it
      • Fit: True to size
      • Size Bought: Small
      • Height: 5'11"
      • Weight: 140lbs

      Very comfortable, slim fitting, excellent ergonomics (as Arc'teryx usually does) and it does breath well as advertised. The face fabric seems impressively durable as well. I ended up going with an Atom LT hoody as it met my needs better with the more wind resistant front and back face fabric, but for those looking for a jacket that provides warmth, some breathability and looks good doing it, definitely consider this.

      Arcteryx sizing has changed

      • Fit: Runs small
      • Size Bought: Large
      • Height: 6'3"
      • Weight: 185lbs

      I used to love Arcteryx because it had a more European fit, and for someone with my build it fit perfectly. I'm 6' 3", 185 lbs with long arms, and I could consistently buy Arcteryx XL and have a perfect trim fit. Now, Arcteryx has gone the way of Patagonia, sizing larger and larger for American chub on the waist. Now almost anything in XL fits in the shoulders and arms but is baggy and sloppy in the torso. If I order Large the sleeves are too short and the waistline rides too high. Therefore I pretty much can't buy Arcteryx anymore. Bummer because I have loved and worn the brand for a long time.

      I have the opposite problem. I'm 6'2 185 and Large used to fit perfectly on me, but it seems like Arc'teryx went with the extreme trim fit lately and I can no longer wear large. When I try XL it feels better in the back, but is way too baggy in the front, which makes it unwearable. They need an in-between size for tall people with wide backs but narrow waists.

      I agree, their fit used to fit me perfectly; snug throughout the body. Their recent jackets fit tight on the shoulders and upper back while being baggy in the gut and lower back. Given this is a technical piece for active individuals benefitting from a snug fit, I think they should have stuck with their previous fit. Bummer

      What have you turned to? IM THE SAME BUILD! Little skinnier at around 175lbs. But same thing. Tall, athletic build with longer arms. Im dying to find some otudoor gear that fits trim and not baggy for chubbier people.

      pretty much perfect...

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Large
      • Height: 5'11"
      • Weight: 185lbs

      I think this is what every breathable, insulated "one tool option" jacket has been reaching for. I first saw this jacket in person at the Arc'teryx store, where the evil, manipulative staff casually suggested that i try one on and go walk around outside, where it was about 30 degrees. With just a baselayer, i was perfectly comfortable... So, obviously i had to have one. Winters in the Rocky Mountains have taught me how to dress -- i know that if i put on a jacket and go outside, and i feel like i'm wearing a space-suit (like w/ Gore-Tex), it usually feels great at first, then i either overheat, or just slowly build up condensation, meaning that i end up wet and freezing, which can get dangerous. The Proton LT doesn't use any type of VBL or vapor barrier membrane, so it stays cool and dry - not "warm". It gets compared to the Atom Lt, but this is really a next-gen garment. There isn't fleece under the arms like the Atom LT, nor is there an uninsulated panel like the Atom SV. Insulation under the arms? You bet. Another thing that amazes me is how this can feel so substantial - the shell feels a little like the flight/ bomber military jackets, only softer. The inside feels almost exactly like the Pat. Nano-Air, which in my opinion would be the Proton's most direct competitor. It doesn't have that "old sweatshirt" comfort of the NanoAir, but it also doesn't have that old sweatshirt appearance. The lack of any kind of baffles or through-stitching makes for a clean, non-puffy look that is attractive and functional. It seems to be as "breathable" (don't attempt to inhale this product) as my Nano-Air, but with significantly more wind protection. It's not as stretchy as the Nano-Air, but it does stretch, and the way it's cut makes it fit so well that it's rare that i have to do something that demands some stretch - but when you need it, the elastane is there ;-) Because of its ricockulous temperature comfort range (50+ ºF), i haven't needed more than a light baselayer down to about 20ºF, but if i move inside to ~70ºF, i stay cool and dry. I haven't tried wearing on 80º days, but i'm wearing it as i write this and i feel the same as i just did walking around the park in 22ºF ("feels like" 11ºF) with blowing snow & wind. I find that amazing. Plus, i LOVE the Graphite color. For those interested, it would make a great urban tactical outer layer, or breathable mid-layer for extreme cold. Best insulated jacket i have ever seen...

      Fit Review

      • Fit: Runs small
      • Size Bought: Medium
      • Height: 5'10"
      • Weight: 175lbs

      40" chest
      32-33" waist

      I didn't buy this, but tried it on at the local Arcteryx store in Boston while shopping for a new shell. I have an Atom LT, so I'll compare it directly to that.

      Fabric: Seems more durable than the Atom, and more closely resembles the Gamma series in overall feel, which I prefer.

      Fit: It feels trimmer overall, and is most noticeable in the waist and arm holes. The waist is fine for me, and had enough room for a t-shirt and wool baselayer. I have larger shoulders, and the arm holes felt restrictive in the pit area. I can't tell if it's fabric build-up, or needs more room in the arm hole/chest , but I found it uncomfortable, and wouldn't like it for everyday wear.

      Open up the pit area a bit, and I'd probably take the Proton over the Atom.

      Best All Around Jacket I've Owned

        I just put 5 Patagonia mid layer jackets on eBay & I'm buying another Proton as soon as they sell! I went ice climbing on a bluebird day that started windy and in the teens and peaked at 37 (F) and I didn't have a breathable layer. I bought the Proton LT before heading out and it performed amazingly ALL DAY long! That was two weeks ago and I haven't taken it off since... The best part is no static shock like all my Nano PUFF & NP Airs EVERY TIME I took them off. 6' 205lbs the L was climbing comfortable but I went with the XL for all around comfort 5 Stars +++

        So So So great

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

        I also have the Atom LT and love that jacket. But the extra water and wind resistance in this jacket is fantastic keeps me toasty as a stand alone jackets even when temps drop into the teens. Its practical in the backcountry, but also casual and sharp looking in town. Super happy with this jacket and definitely digging the external chest pocket for all my extra chapsticks.

        Warmth in Any Weather

        • Familiarity: I've used it several times
        • Fit: True to size
        • Size Bought: Medium
        • Height: 5'11"
        • Weight: 165lbs

        Whether you're waiting your turn on the crag, chasing face shots on a powder day, or if you're simply trying to look good on a Friday night, the Arc'teryx Proton is perfect for any activity.
        It provides enough warmth to make an amazing outer layer on brisk spring or fall days and an even better mid layer on colder days, while you're riding the lift up to get that perfect line.

        Insulated jacket for any activity

        • Familiarity: I've used it several times
        • Fit: True to size
        • Size Bought: Large
        • Height: 6'2"
        • Weight: 185lbs

        The Arcteryx Proton LT Hoody is a super breathable and dynamic insulated jacket that excels when you're getting active. It's a great outer layer for hike in the fall, and as soon as the temps drop, throw a shell over it, and you'll find that it's not too bulky, and allows your body to breathe while staying warm. The fit is trim, so it can layer easily - if you like a more generous fit, you may want to consider sizing-up. I am 6'2" 185 and the Large is great for me.

        Unanswered Question

        Compare to Patagonia Nano-Air hoody or jacket which feels more durable with outer material?

        I can not decide between jackets. Thx.
