Description

Built for dynamic alpine activities.

First and foremost, Arc'teryx shaped the Men's Gamma MX Softshell Jacket for mobility and outfitted it with highly breathable shell fabric for comfortable temperature regulation. Alpine climbers and backcountry skiers can wear this midweight jacket alone in mild, mixed weather conditions, or they can wear this jacket as an insulating layer beneath a storm shell.

  • Lightweight shell fabric breathes easily
  • DWR coating causes light precipitation to bead and roll off the surface of the fabric
  • Fleecy interior face of the shell fabric provides a touch of warmth
  • Articulated cut and gusseted underarms allow for full range of motion and freedom of movement
  • Hip-length jacket has slight drop tail for added protection

Okay, I've got to be honest, I wasn't crazy at first about this jacket because I bought it during the winter looking for a casual jacket that could be used hiking/backpacking. It has a light fleece backing and let's in some wind so as a casual winter jacket you still need to layer with other stuff. This all changed once I started exercising in it. I started running and then did a number of day hikes and have to say I was very impressed. The jacket really shines when you are doing heavy physical exersion. Before I'd have to constantly take off and put on layers to regulate body temperature, however the Gamma MX practically eliminates this need in colder weather. If you stop moving for awhile you'll eventually need to put on a puffy. Other things worth mentioning is that it has great storage. Pockets are very smooth and will hold keys, lip balm, phone, etc very well. There's no interior pocket but that's a minor detail. As a casual jacket it's much better suited for temps above 50 degrees, but looks great no matter what the temps. Great product!

For those of you who have this and an Atom Lt or have at least tried on an Atom lt, is the fit about the same? I can wear a small in the Atom and it's snug, so I'm trying to figure out size on this one. thanks.

Used couple times for hiking with phase base layer in low 30s no wind no rain conditions breathability is amazing sucks the moisture out of base layer and throws it out. Careful with chest pocket i had a phone there and it literally had drops of moisture on it coming from inside.

work amazing in no wind no rain condition but doesnt stop wind so its perfect for low 30s maybe even 20s when you on the move

Some modern-day Rambos n bimbos will find this piece useful for capturing wild mountain cats with a thorn in their paw with their teeth and then running them to the nearest vet across the Nevada Desert when they celebrate with a cup of water and a carrot. For some of us, its super stretchy material allows full access to a beer and a Marlborough Light. A versatile, comfortable jacket that can be worn spring skiing or just around town.

What is the difference in length with the Large and Medium? I wear a medium in the Hyllus and its pretty snug, but fits in length. Any suggestions on what size to go with for the Gamma MX. Im 5'8" with broad shoulders.

Hey Mike,

+/- 1" in length between sizes. That goes for sleeves as well.

Thanks Josh. Does anyone know if this fit is the same as the Hyllus?

I love this jacket: warm, flexible/stretchy, durable, good fit. Office or crag. Or summit attempt as a weather-ready layer under the puffy.

Best all-around for me

I love the feel of this softshell material. It is super soft and stretchy. I'll second some of the other reviewers that the jacket is a little thiner than you'd think. I had a hooded Gamma MX from a few years ago with polartec face fabric and I think that my older jacket was a little more windproof but this new one is definitely more comfortable. The thinner material is very breathable and would be great for layering. I'm 5'9", 175 lbs and the medium fits great.

How is fit? I'm 220, 6'4", looking for something to layer under a shell for skiing

XL would probably fit you well. But this wouldn't be the best choice for a piece to layer under a shell. It is only lightly insulated and has a soft shell to it, which adds no value as a mid layer, yet a lot of money. It probably is similar to a Delta LT as far as insulative properties , maybe a bit more, but less than a Delta AR, but much more expensive because of its shell properties. I do recommend either of those as a mid-layer, and maybe both to have flexible options.
This can be used as a mid layer, but the purpose is more to use this as the outer layer most of the time, while putting a hard shell over it when you need more protection from precipitation and/or wind.

Everything about this jacket is amazing...perfect to wear over a layer when you want to be really warm...warm enough to wear alone with a t shirt from 40 degrees F and higher...matched with an apache fleece and you're super warm! Tons of useful pockets! Very durable, water resistant, great fit, soft, I would buy every color if I wanted to spend 1200 bucks! Perfect jacket IMO

Ordered the GMX in summit sky/small. Awesome color-call it a deep blue. 5'10"/150 - small fits right on with a light shirt. Best feature is it's breathability - comfortable indoors/warm outdoors. Get one!

Superb all-around piece. I use it almost year-round, from 60 to 25. The key is to remember this is an aerobic piece built for action. It has incredible body temp management ability and the new Fortius material is a significant upgrade over the previous version. It blocks 90%+ of the wind and sheds rain up to a downpour. Be sure to use a baselayer underneath for 35 and below. If pressed, this could be the only jacket in your closet. I can't say that about any other piece I've owned. Also, the fit is more generous than previous models, but still athletic, so it's more true to size and much easier to layer underneath.

I own multitudes of arcteryx products. the gamma MX is probably the least bang for your buck that you'll find. I got it on sale for $149 and I felt I barely got my value out of it at that point. Yes it cuts some wind and blocks most all water, and it is somewhat warm but it wont keep you going under 38 degrees. I use it as an early to late fall casual jacket and april on to late may nights.

I find the MX to be the best all-around piece I own and therefore worth the price. Unlike the Hyllus, which I also own, the MX is built for action, so it won't warm you much on its own below 35. But with a midweight baselayer and some aerobic action I've been very comfortable in wind and snow at 30-25. Of course it's perfect for conditions up to 55 or 60 depending on wind. The new Fortius material is much better at shedding wet and blocking wind than the previous version. I suppose it depends on how you use it and what you need.

Your comment makes a lot of sense. I used it for a walking jacket, without aerobic action, its a tough sell, but you bring up a great point, maybe that wasn't what it was designed for.

Can anyone comment on the wind resistance?...

Can anyone comment on the wind resistance? I'm not familiar with Fortius 2.0.

Benjamin Vincent

The wind resistance is pretty good. It's not 100% like windstopper, but it breaths SO much better. It's about on par with polartech powershield, or 96-98 % roughly. I haven't been in super windy conditions, but at 20-30 mph I don't feel any wind. Fortius is Arc'teryx own proprietary material, with the number - 1.0, 2.0, 3.0 - referring to how thick the fleece lining is. 1.0 is pretty much none or just a shell, 2.0 is a light fleece lining and 3.0 is a thermal layer.

It has two hand pockets and a chest and (small) arm pocket and the collar zips up to well below the chin, say about half turtle neck length on most people. I have a freind that is a real pencil neck and it looks like a regular collar, but then again , he's built like a giraffe.

There are 2 hand pockets, 2 chest pockets (just look at the picture of any color but black, there are zipper pulls visible on both sides of the chest) and a sleeve pocket on the left arm. There are no interior pockets. The collar is of medium height.
