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

Here's what others have to say...

What is the center back length of a medium?

Is it possible to get the sleeves tailored shorter? The XL fits perfect on my larger arms but the sleeves need to be about 1.5 inches shorter. Not sure if my local tailor would be able to get the job done.

Responded on

I would say that it's possible, but the tailor would probably ask that you exonerate them regarding any situation that might result in an undesirable outcome for the jacket, and consequently, you. If I had to guess, I think you would be hard-pressed to find a tailor that would take on that project; I would think that there is a relatively high likelihood that the tailor would have a difficult time restitching the necessary pieces into place, on top of the fact that it would very likely reduce the performance capability of this jacket. I would assume Arc'teryx would use some specialty thread and/or glue to secure their fabrics together, so I personally wouldn't risk taking it to a tailor, but like I said, I'd say anything is possible.

Responded on

Thank you for the reply. I've seen a few people in forums talk about people who specialize in tailoring gore tex stuff and was hoping maybe even a regular tailor could handle it. Seems like it would be a big hassle though and probably not worth the trouble.

What is the difference between this jacket and the Epsilon LT in terms of fit and function? (Other than the chest pockets)

Best Answer Responded on

The Gamma is not as breathable as the Epsilon. Its going to be a warmer jacket but, the Epsilon will breathe better. I would use the Epsilon jacket for more aerobic adventures or if you just run really hot. They both will fit the same.

How cold can this jacket tolerate? Can I...

How cold can this jacket tolerate? Can I trust this jacket with temps that dip into the 5 to 10 degree range (assuming I stay somewhat active)? I know I would have to wear some sort of baselayer, but, is this jacket capable of keeping someone warm in colder temperatures?

Responded on

Hey Steve,

There's no accounting for personal comfort levels, but without a pretty heavy baselayer, I'd be nervous about this piece in 5-10 degree weather (assuming we're talking Farenheit, anyway.) This jacket is only very lightly insulated-- the new Fortius 2.0 fabric is laminated to a 160 gm weight fleece, but it's definitely still a softshell, so you'd likely need additional warmth from other layers for serious below-freezing temps.

Please give me a shout if you have any other questions! 800.409.4502. ext 4456.

Thanks Lara, I appreciate your input.

Steve... for just walking around town, I'm comfortable in this jacket into the mid-thirties with just a t-shirt underneath (assuming no wind). Lara seems tougher than me.

Responded on

Haha, thanks David. Good perspective.

Steve, Ive had this for a winter and its not bad for 40's or higher, but it is defiantly not that warm. I have a Lorum jacket now with Polartec and for the same thickness, they Lorum is much much warmer. However, if you are looking for a late summer-early fall jacket, its not bad.

Responded on

Kyle, thanks for your perspective. I appreciate it. I eventually decided against this jacket, mainly because of the reviews here in response to my question. I'm certainly not doubting this is an amazing jacket, but it isn't the right one for the purpose I need. I was really looking for something warmer that can tolerate really cold temperatures.

whats the difference between this yrs model...

whats the difference between this yrs model and last years?

Responded on

There is no difference between this current years model and last (except some colour changes). If I recall the last time they changed the jacket was in the Fall 12 version when the revised the cut/style of jacket and changed from polartec powersheild to the current fortius 2.0 fabric.

Responded on

so im guessing fortius 2.0 is better than the polartec powershield as far as materials go

Responded on

Fortius is a bit more breathable and is slightly warmer than the old Polartec PS. This is not based on any scientific testing but just regular usage of both versions of the jacket. I did find powersheild to cut the wind a bit better. lastly I find the fortius fabric seems to resist fading and the discolouration at he cuffs and hems.

Do these run slimmer than Epsilon series?...

Do these run slimmer than Epsilon series? I normally wear a small but I found a clearanced small in nightshade and it was tight. Thanks

Responded on

The epsilon series is wider in the Chest (since the fabric has less stretch). Shoulder witdth is about the same. The new epsilon LT however is much slimmer than the old AR/SV series .

Handsome Blackbird

  • Familiarity: I've used it several times
  • Fit: True to size

Fell in love with the unique design of the jacket. The two chest pockets and logo really set it apart from the crowd. I got the Blackbird in a large. Its sporty and handsome. I'm 5/10 160 athletic build and the fit for me is near perfect. I use it for hiking , walking and for going around town. These things aren't cheap, but hey Arc'teryx is Arc'teryx.

very good jacket

  • Familiarity: I returned this product before using it
  • Fit: Runs small

Very good quality and well made. Only problem is it's a very slim fit. I am usually medium size in all other brand ( TNF, Mountain Hardwear, Patagonia ... ) but Arcteryx is so tight that can't wear anything under it. And sleeves are little too long so I can't wear large. If you are slim and long type than go for it.

My Favorite Jacket

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This jacket is incredibly comfortable and holds up well against the wind and rain. This is my 'go-to' jacket in my closet. I'm 6"5 220lbs and went with a Large. Great fit. Plenty of sleeve length and fits well through the body.

Responded on

Hello Stephen. did you layer much? I'm 6'2", 227 (and dropping) and usually wear an XXL, certainly would in an ArcTeryx. Was a large very trim/snug for you? Thx

One of the best jackets I've worn.

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This jacket is phenomenal. I bought it little over a year ago when on sale. Since then I've used it for just about any activity from skiing to climbing. One thing I love is how durable it is. I was in a cave a little over a foot white and was sliding through it wearing this jacket. I thought it would surely show signs of the scraping in the cave but nope, it withstood all the abrasion with no problem. Another thing I love is just how versatile it is, it can be worn as a stand alone piece in moderately cool weather, it can be a layering piece, and it also has enough room for more layers underneath. When spring skiing i wear this and another layer underneath and am completely warm. It is advertised as water resistant which it is, but it really takes alot for it to give, and it is also fully windproof.

Pros: Versatile, Comfortable, Great weatherproofing, light/packable, stylish, decently warm.
Cons: Requires more layering for colder weather, price

Overall this jacket is great, it is a great piece for just about anyone wanting a daily use jacket that can still hand up to just about anything thrown at it. Must buy!

Not as good as previous incarnations

I bought this to replace my 2nd Gamma MX since I got a screaming deal. I am sold on the concept of this jacket and use it as a light shoulder season jacket on it's own and a layering or high exertion piece in the winter. I rarely use sweaters, fleeces anymore since buying the MX. Between a short sleeve or long sleeve base layer, the MX, and a shell in various combinations I'm set for 85%+ of the conditions in CO. I swap out the MX for an insulating layer only when it really gets really cold.

That said - I don't like the new Fortius material nearly as much as the old. The face isn't as slippery (read harder to use for layering) and it feels warmer, but not in a good way. Where it used to be a perfect for 35-60F depending on level of activity, it now feels too warm at the higher half even as a casual piece.

I also don't like that they relaxed the fit of the XL. Now too roomy in the arms and gut even for a big guy. It is much less athletic. I'm a big fan of Arc for not assuming that all XL guys are fat arses like NF does, but they headed in that direction in this version of the Gamma MX.

Long and short is that I sent this back and will ride out my current MX until it is really threadbare.

Responded on

great review from a perspective of an older model owner. i was planning on upgrading from my 3 year old Gamma MX, and per your review, I've decided to wait to see if they'll revert their design and fabric back to those of the older models. Chances are they won't which is sad. What I love about my older model is that it's trim fitting, but has plenty of length in the arms, and as you said, it's very versatile in a wide range of temperatures. Sad to hear indeed.

Responded on

Based on your great review I want to buy one!
Speaking as a fat arse XL, just the jacket I need. It will accomidate my man-sized proportions, instead of catering to the stick figure set. ;)

Responded on

Neo, if that's the case you'd love most of Patagonia's sloppy sizing these days too...

Gamma makes me even handsomer.

Gamma makes me even handsomer.

There are a few layers under here. SO comfortable, flexible, warm and breathable.

Pocket linings

Pocket linings

All four pockets are lined with mesh. What that means is that they serve as ridiculously effective vents if you open them. (It also means they aren't really "cozy" as hand warmers, and that if you want your pocket open for some reason you need to suffer a breeze.

Among my very favorites

  • Familiarity: I've used it several times
  • Fit: True to size

This jacket is one of my favorite things. Functions well in the wild, looks sharp around town.

It has a huge temperature tolerance and I wear it from the low sixties into the mid-thirties.

All four pockets also serve as vents for the jacket and are lined with mesh. Wind resistance is pretty good, but the jacket breathes so incredibly well it's amazing.

Has been holding up well to near constant use in the three colder seasons.

I'm 5' 9" and 185 lbs. Do you think a medium or large would fit better? Thanks!

The large will fit and leave you a little room to layer underneath. I'm 5'10" 200# and the large fits like it's tailored for me.

Responded on

Depends on what you want it for. I'm 6'1" 175 lbs, 40 shoulders and a 32 in waist. I fit in most all Arc'teryk gear in a medium with a good athletic fit that doesn't look stupid by its self, but has enough room underneath for some layering if need be (base layer and thick fleece). You would fit in the Large fine, but it will probably have a bit more room and not be as much of an athletic fit. Comes down to how many layers you want to throw on under it basically.

Responded on

Arc' Jackets are a bit tough to fit for guys in the 6ft/170 lbs/40-41 inch chest/32-33 inch waist size unless you have really long arms. I wear a 16/33 inch sleeve length in a dress shirt. The large fit great everywhere except the sleeves. They simply swallowed me. So opted for the medium. A little tighter fit in the chest but not unreasonable. The plain fact when you're sized like we are, you're going to have to compromise in almost any article of clothing you buy. This size sits squarely in the middle of M and L!

Great Jacket for what its Designed for

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!
