    Finally, you can keep that hardshell jacket tucked away until the weather turns REALLY nasty.

    Move freely in mixed weather conditions while you're wearing the Arc'teryx Men's Gamma MX Hoody. Articulated arms and a trim fit keep this midweight layer close to the body without restricting movement when you're alpine climbing or sliding up a skin track deep in the mountains. More versatile than your baselayer and more breathable than your storm shell, this jacket will be the one you live in the most, even if there's a little light precip falling from the dark clouds above.

    • Fortius 2.0 synthetic fabric insulates for warmth, dries quickly, and allows moisture to move away from layers underneath
    • DWR coating allows the fabric to repel light moisture
    • Trim fit keeps this jacket close to your body for warmth, and gusseted underarm construction allows for full range of motion
    • e3D patterning brings an additional level of articulation to the fit of this hoody—articulation designed specifically for each intended activity (climbing, skiing, etc)
    • Long torso length slides over the top of your pants to help keep the elements out
    • Storm hood easily stretches over a ski or alpine climbing helmet

    a little dispointed

      this one is made in vietnam, a little different from the one made in china, the not hoodied version i bought. the brand at the front chest is more shinny for the latter. their materials showed in the tag are different too.
      the collar is too wide to block strong wind, but the not hoodied one can.

      Go To Alpine Softshell Jacket

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Medium
      • Height: 6'0"
      • Weight: 175lbs

      Gamma MX is critical piece in my alpine layering system. It's versatility is amazing as it accommodates a wide range of conditions. The hood, main zipper and vented pockets are all key to it's capability. With the hatches battened down, this jacket is as warm as a UL puffy. Fully open, it has excellent breath-ability. Of course, it can be fine tuned across that range.
      Fit is athletic. Easily accepts base layer and mid-weight insulation layer (eg R1) with full freedom of movement. My belay jacket and hardshell are sized to on top of it.
      After 4 seasons, it still looks great! The exterior fabric is very durable and has not started to show signs of wear.

      Perfect soft shell

      Love this thing. Wear it all the time. The only downsides I have are the sleeves are a bit long and it marks easily, but the marks also go away easily.

      Worth the money

      I was hesitant to buy such an expensive jacket. I had heard great things about Arc'teryx, but it took me a long time to convince myself to buy such an expensive jacket. I wish I wouldn't have waited so long. This is the jacket of my dreams. It breathes, protects, keeps you warm, and allows great maneuverability. Beware of it's athletic fit. For someone as tall as I am, it comes a little bit short, but still fits me better than mostly anything I wear.

      I use this jacket for touring, mountain biking, hiking, casual days, and just about anything that requires me to wear a jacket. I would recommend this to anyone.

      So just a comment about my favorite softshell's color...
      Blackbird is the most beautiful black. All other black garments i have look pale and washed-out compared to the deeply saturated, extra-dark Blackbird color. The best black fabric i have ever seen...

      Update: Another cool thing (no pun intended) is that this Blackbird color doesn't seem to be as susceptible to solar-gain as other black jackets i have had (which is pretty much all of them - i'm a big fan of black clothing), kinda like ColdBlack... I appreciate this a great deal, since solar gain can cause temperature flux, leaving you too hot when in direct sunlight and then cold and clammy when in the shade. So it takes one more variable out of a cold-weather clothing system, which is rad.

      Stylish fit and great performance

      Pros- stylish cut, good in light rain, blocks wind, big hood, staple layer -meaning this jacket won't live in my closet
      It's either in my pack or I'm wearing it.
      Cons- Not really anything to complain about. I can agree with other reviewers about breathability. It's not great to wear while skinning. This is the layer you put on after skinning. I am looking at the OR Ferosi for skinning.

      Perfect jacket!
      I love this jacket, it's anti-wind, it's small to medium rain, warm.
      In my city, winter is enough.

      Winter Do All

      • Size Bought: Large
      • Height: 6'1"
      • Weight: 195lbs

      I wear this jacket in every condition during winter. This jacket is perfectly suited for climbing and skiing. I am 6'1 195lbs and the Large fits me perfectly. Arms up, down, twisting around, this jacket keeps you covered. The hood also moves with your helmet when you use the cinch, eliminating blind spots.

      I like what you said about eliminating blind spots. Incidentally this also works with just a hat on underneath - if you cinch the halo cord the hood moves with your head, which i appreciate while doing anything, even while driving, to check to see if the coast is clear before switching lanes or whatnot. It sucks when you look over your shoulder and all you see is the inside of your hood :-( I never have that problem with any of my Arc'teryx hoodys...

      Ice Jacket

      • Familiarity: I've used it several times
      • Fit: True to size
      • Height: 5'11"
      • Weight: 155lbs

      THIS IS MY ICE CLIMBING JACKET. PERIOD. I've battled with hard shells, softshells and switch it all around and this is the end all jacket. The fit is amazing. I'm 6' and 155lbs and I'm in a Med. I also run a bit cold and I don't sweat much. I can wear it with just a base layer alone on "warmer" days or when I'm on lead or I pair it with the Patagonia Nano Air Hybrid for a perfect midlayer. The pockets, fit, breathability and the super thin fleece layer is so worth the price tag. This jacket actually moves with you! Also, the hood with the neck and face protection is roomy and comfortable when wind picks up.

      Ice Jacket

      Super comfy soft shell

      • Size Bought: Small
      • Height: 5'6"
      • Weight: 150lbs

      Yes, it is an expensive jacket, but I'm starting to think it's worth it.
      I initially bought it for a Mt. Fuji hike and it handled the mist/fog while still breathing and keeping me cool.
      Took it out in a moderate rain the otherday and while it's not a waterproof goretex hardshell the water repellant lining kept me dry.
      Fit wise, it's probably the best fitting jacket I've owned without being restrictive.
      I've now adopted it as my everyday jacket because it's so comfortable, has a ton of pockets (5), and is fitted/fashionable enough to wear afterwork.
      Highly recommended.

      Excellent soft shell so far

        So far I have used it primarily for skiing and secondarily for hiking (several days of each). All but one were clear; that one was a Cascade drizzle and the shell shed that easily. It also breathed well, although it was alpine rather than Nordic or touring skiing.
        As to fit, I'm 5'10" and 150 and the medium was perfect. Someone with larger wrists is likely to have a problem and I would also prefer Velcro to the elastic.

        A nice jacket but is it worth it?

        • Familiarity: I've used it several times
        • Fit: True to size
        • Size Bought: XL
        • Height: 6'1"
        • Weight: 200lbs

        So far I've used this jacket travelling and just casually about. It is a sharp, lightweight versatile jacket however i think the front is cut a little too high for me, and the sleeves are a little too long not major problems just take away from an otherwise perfect fit. The hood is massive as well. Other than those things for casual use and urban travelling its a great jacket, My other gripe is the price its cost at least 2X more than other soft shells, I hope that when i take it hiking and snow boarding it really performs and I can say i love it.

        Gamma MX Hooded Softshell Jacket

        Classic unbeatable arcteryx fit. For the folks who complain that this jacket doesnt have velcro cuffs... no insulated gloves that are truly meant for climbing or skiing will be designed to go under-cuff. My ice climbing gloves work perfect over these cuffs, and my gore windstopper gloves (for not so cold days) fit just fine underneath the cuffs. I wouldnt have it any other way. This thing sheds snow like a beast, and the storm hood is absolutely perfect whether you have a helmet or not. The reason I prefer this over a hard-shell is that this jacket provides protection for MOST of what people encounter withe the weather, and also you wont over-heat when you work in it, but youll still be warm when you just sit around. A whole day of ice climbing in Hylalite Canyon, Montana and I never had to put on my belay jacket or need to unzip to prevent over-heating.

        Gamma MX Hooded Softshell Jacket

        Blasted cuffs

          I really wanted to love this jacket. Perfect fit, perfect color, perfect brand/quality BUT...the cuffs not being adjustable to wear gloves under the cuff was a deal breaker. If you like over the cliff gloves this jacket is ideal, but I wear ranch style winter gloves and I couldn't manage to keep the jackets cuff over my gloves. I had to regretfully send it back. Other than the cuff this jacket was perfect. 4 stars for the jacket -1 star for the cuffs

          Not to be contrary, i wish all of my jackets had cuffs like the GammaMx. They are just perfect - i can stretch it over a big diving watch, or a close-fitting glove like the Venta or Rivet, and perfect for under-the gauntlet type of mittens for extra cold/wet weather. To be honest, most adjustable cuffs i have owned i don't really use the velcro - just set it and forget it. These cuffs are perfect since there is no velcro to snag on mid-layers and gloves and such. Just my 2¢

          Arc'teryx – Men's Gamma MX Hoody

          This wind-resistant, breathable hoody is perfect for alpine specialists looking for enhanced mobility. A tough, highly wind-resistant outer face sheds moisture and a light fleece backer adds warmth while wicking away moisture.

          Most comfortable jacket ever.

          The good is it's well made, fits well, is nice and stretchy, has an adjustable hood that's not annoying w/o a helmet and allows good peripheral vision.

          The not so good. With a medium size Gamma MX, a Delta LT fleece and t-shirt, this feels tight. Wouldnt be very comfortable to hang out in or climb. The interior fleece lining is comfy but isn't that thick of course.

          Therefore I think maybe the Gamma LT is better because it gives you a bit more room on the inside to layer as needed. The down side is the MX has better pockets.

          IF you zip it up all the way, but without the hood on, it ends up over your chin and very awkward.

          I was looking for a softshell jacket that allows my head moving easily with helmet. My previous Mammut Ultimate Hooded Softshell Jacket doesn't work this way because the hood was too small. I have ordered three jackets including Patagonia Kniferidge Softshell Jacket and Black Diamond Dawn Patrol Hooded Softshell Jacket. After trying them at home, I decided to keep the arcteryx one. This is thicker and warmer than any softeshell jackets I have tried. So it will probably a little too warm for fall and spring activities. Very wind resistant. Hood is big enough but it feels a little empty without helmet but I understand I can't expect it to be big enough and tight enough.

          Glad I made the right choice
          Unanswered Question

          When wearing this around town is the front long enough to cover an untucked shirt or will it be showing? Also is the cut big enough to fit a heavier weight fleece or even a hoodie underneath? I need a dual purpose jacket for spring/fall around town and snowshoeing and xcountry sking without sacrificing quality. Suggestions, keeping an athletic fit and quality in mind, i.e. not North Face's new garbage.

          I am looking for a soft-shell (alt. insulated mid-layer/shell like the Atom LT) to complement a hardshell jacket.

          I live in a cold climate, -10 – -25 C° is not unusual, add some wind to that, it gets pretty chilly sometimes. I am going to use it for backcountry ski touring and nordic style touring, but would like to be able to use it for spring and autumn tours as well (askin to much?).

          I am not sure if this model or the Gamma SL is to be preferred? As I understand this has the fleece liner and the LT does not.
          If I were to use a thicker fleece (or down sweater) as a mid-layer in the SL, would it be as wind-resistant as the MX? Could you use the SL with a thicker mid-layer such as a thicket fleece or down sweater in really cold weather? A Gore-Tex Pro Shell would always accompany me on winter tours. As I understand the Gamma SL has a bit better breathing ability compared with this model, which I find important.

          If you have any suggestions, I would appreciate it!

          -25C is quite cold. If you'll always have a Gore-Tex shell with you I'd consider either the Gamma MX to the Atom LT but probably not both. I have an Atom LT and love it, the side panels help with breathability. Since Nordic skiing backcountry touring are pretty high output, probably a base layer followed by one of the above will work well. I believe Atom LT will offer more wind 'resistance' than the Gamma MX. But of course you'll also have your hard shell. Hope this is of some help.

          Larger Person: 6'4", ~230 pounds, 38" waist, 18" neck, 36-37" arms - will XL be too small in this product?

          Am used to looser fit of snowboard-styled gear, am willing to deal with something a bit more "athletic-cut", but at my size, I don't want it to fit like compression wear. Larger riders/climbers/backcountry snowshoe/backcountry splitboarders weigh in, please.

          Also, I didn't see pit vents/zips mentioned, does this have them?

          Advice on XXL vs. XL?

          Hi Theodore,

          I'm 6'3" and 215lbs w/ a 34" waist (athletic build) and I wear the Large. I like my jackets fitted and the Large is almost too big for my taste (it's a little baggy around the stomach area), but when it comes to performance, this jacket is the best I've ever owned. I love the "no-lift gusseted underarms" which lets me climb without flashing my fellow climbers coming up behind me (crack kills). It performs great in rain / snow, and most importantly, it breaths well. The kangaroo pockets are vented and there's also vents on the chest pockets, but there's no pit vents.

          The one thing I don't like about this jacket is how tight the cuffs are. Getting the jacket off can be a chore.

          To specifically answer your question, if you want it fitted, I would go for the XL, if you want to add several layers and want it to be looser, go for the XXL.

          For people who is wearing this jacket over Atom LT, what size would you suggest? I have atom LT in small size. Should I get S or M gamma MX?

          So, I've read all the reviews & have a great feel for this jacket. I'm really wondering if the over-sized hood is really useful for everyday cold, rainy NW use or it's just handy when wearing a helmet. I love the idea of the hood, but if it doesn't fit well, then it's usefulness is a little tempered for casual use. Anyone out there wear this everyday & find hood fit ok for basic NW chilly, rainy days?? Thanks for any responses in advance, happy upcoming POW days!

          Best Answer

          First of all, as a NW guy myself I want to make sure you realize this is not a waterproof shell. You will get wet in a sustained down pour though it will protect you from light or intermitant rain. That being said, I love this jacket. I understand you concern about the hood. When you first throw it on sans-helmet you wonder if there has been some mistake. But several draw cords allow you to cinch it up to a nice snug and protecting fit. If you are just using this jacket for surviving the rough and tumble weather of the North-West I would recommend something with a normal hood, but if you will be wearing a climbing or biking helmet at least 20% of the time, then the oversized hood is perfectly manageable and worth the sacrifice.

          Amazing, thanks MD Hilverda! Just curious, what jackets do you think are best for everyday NW weather (normal hood)?? I'm gonna grab this one for biking exploits, etc...but you can never have too many jackets in the NW, right???

          Arcteryx softshell match-making time.. So,...

          Arcteryx softshell match-making time..

          So, I am looking at replacing several of my jackets and have heard good things about softshells. I havent had one for years after having a poor experience with a TNF softshell that didnt fit well many years ago..

          Uses: Im looking for it to be used all year around here in the PNW. I was a bit worried about rain resistance but heard softshells are actually quite well. I have an OR foray shell if needed for heavy downpours. In the major attraction point is breath-ability, I sweat like crazy. I usually wear shorts year round, as I did in MN where its actually winter when I grew up and hardly ever use my marmot ama dablam down jacket. Id be using it for casual, around town/to work, snowshoeing maybe downhill skiing in winter, and hiking and backpacking the rest of year..

          Size wise: Im hoping to maybe layer a small layer underneath, Im a out of shape 185, 5' 10'', with a stockyish build. I usually wear mediums in patagonia, but got a large atom LT half zip.

          Sorry for the book, mister librarian. Any help would be great. Oh and ive been looking at this one, vs the venta mx, and gamma lt. All hooded. Hoping to spend around $250 (and find it on sale obviously). Thanks!

          Best Answer


          Honestly, I have a Gamma MX and find it to be very cold unless I'm staying active, so from what you say plan on using it for, probably not going to cut it. The fit is athletic [snug], so plan for going up a size for anything but the thinnest layers under it. Not especially good at holding out "rain", but until the DWR coating wears off with use or washing (you can refurbish it) it does a good job of shedding moisture. Great jacket when used right!

          In Arcteryx, I would go for the hooded Venta SV if you want to stay warm, especially when just using it casually. I would go with the large.

          Hope this helps you out.

          Thanks for the advice, much appreciated! So I run really really warm usually, (I blame growing up in MN) and now having just moved to the PNW, have realized its temperate here, thats why Ive shied away from looking at the venta. I went to REI to try on some arcteryx softshells but unfortunately they arent in stock yet! I did try on the beta (or the alpha) and the medium seemed to fit well with my nanopuff vest on underneath. Also from what ive read the gamma should breathe better than the venta.. Should I look at the gamma lt?

          Go for the gamma lt. It has a good balance of breathability and windproofness. The venta sv, although it does have pitzips, is not very breathable. It has a windstopper membrane, so is slightly more breathable than a hard shell, but I overheat in mine enough to not wear it very much. Also, the thin fleece lining makes it less versatile-not enough for real cold (I'm in Canada) and too much for above freezing. The gamma is great for above freezing, and with the atom lt underneath is good in the snow. It fits a little snug though, so think about sizing up.

          Best Answer

          I'm 5'10 and 165lb, and the medium fits really well. The arms and length are perfect although the torso is a touch voluminous. That being said on the Small, the arms and torso were too short while the volume was just right. For me, I'll take the mobility and perfect length over the perfect volume.

          Hi all, I have a question in regards to the sizing. Which size would you recommend for an athletic build 5'10", 185lb, 43" chest, 33" waist? I'm leaning towards a Medium but would a Large be better? I prefer a fitted jacket rather than a bulky one. Thanks for your help in advance. Cheers!

          Best Answer

          Large most likely, due to your chest and waist. I wear a mediaum (6' 145lb 39 chest and 30 waist) with a midlayer underneath the jacket fits perfectly, and on its own it is very comfortable withought being bulky or boxy looking.

          There shouldnt be much of a size difference between the hoody and non hooded version.

          Thanks for the response Ethan. I tried the medium on and it has a better overall fit than the large but the chest area was a little tight. This jacket will be my main one during the 3 seasons other than winter so I'll most likely only be wearing a t-shirt or a thin baselayer (arcteryx delta lt or patagonia capilene). Would you say this hoody version would be a bit bigger than the non hoody one? Thanks again!

          Just wanted to add that I got the hoody version in a size medium and it fits perfectly. I can wear a t-shirt, baselayer or a fleece sweater without any issues. Also the hoody version's fit is a bit bigger than the non hooded one. Thanks again for your suggestions! Cheers!

          I am wondering how well this Shell really is. I will be climbing Mt. Fuji for the secound time but this time it will be next November. Will this shell be enough with proper layers or should I invest into something warmer? Temp at the summit can be around 10-20 Below 0 and around 50-60 at the base. please help

          You're going to need something more wind proof. You probably should bring some sort of hard shell, for example an Alpha SL stowed in your pack for when it gets cold and windy. Or any alpha, beta, or theta.

          If you don't sweat a great deal, a Windstopper soft shell might serve you well from top to bottom, with varying layers underneath.
