Gamma MX Hoody

Move freely in mixed weather conditions while you're wearing the Arc'teryx Gamma MX Hoody. Articulated arms and a trim fit keep this midweight layer close to the body without restricting movement whether 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.

  • A versatile softshell jacket for alpine sports in mixed conditions
  • Stretch face fabric defends against wind, rain, and abrasions
  • Fleece lining insulates for warmth, dries quickly, wicks moisture
  • DWR coating sheds light precipitation if you encounter weather
  • Gusseted underarm construction allows for full range of motion
  • e3D patterning brings an additional level of articulation to the fit
  • Long torso length offers additional rear coverage while active
  • Storm hood easily stretches over a ski or alpine climbing helmet
  • Item #ARC3414

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.

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!

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!

Hey, 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.

I am 6'4" and 165 lbs. Should I go for the Large?

I am about 5'10 and 180 lbs. I use a medium but I would say since your a bit taller you couldn't hurt to try a Large, especially if you plan on layering.

Fortunately, Acr'teryx makes their sleeves long, so a LRG should work well even though you're pretty slim. (I'm a similar build, and have found a LRG to be a nice fit for this brand.)

What size would you guys recommend for 5'10'' and 165lb?

Thanks!

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.

Agreed I'm 5'7" 165lbs and the medium is perfect for me as well

Hi all, I have a question in regards to...

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!

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've got a question about the Cayenne color. Does anyone know if the color up on the web page is accurate? It looks more orange than red to me. I ask because I know on my past Arc products the colors online have been really different from the actual color.

Adam, I've been wondering the same. Have you received any replies or have you seen the Cayenne color in person? I kind of like the orange-ish color. Any help would be great, thanks!

I have seen it in stores and its really red. Looks awesome though but I went with the blue myslef

I am wondering how well this Shell really...

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

50-60 you are fine, I would say in the 30's and you would be cold in it. Remember its not windproof.

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.

From summits, most likely you will definitely need wind proof material! This will feel so cold if you get up on a mountain and start to catch wind no matter how many layers you have!
