Arc'teryx Gamma MX Jacket - Men's

I've owned this jacket for over a year and it has been surprisingly warm for how thin it is. Very very water resistant, and overall a ten. I wear it around town and use it in technical settings and it can outlast other jackets in its class. I also work at a retailer focused on outerwear and this jacket is highly sought after as a technical piece. We endorse Arc'teryx above all others because of the quality and industry leading innovation they instill. The Gamma MX is a great first softshell or addition to your arsenal. I highly recommend this jacket.

Bar none this is the best jacket I've ever owned! Hiking Rainier this past summer I loaned this jacket to a buddy on the trip who forgot his hardshell, we got caught in a blizzard with 50mph winds and he was totally warm using this jacket as his outer layer. The Polartec Powershield fabric is great because it's windproof and highly water resistant. This is my everyday jacket around town and also works for a good majority of the days in the mountains.

I am 5'10" 150lb.= a lean build. The medium fits me very well, sleeve length is perfect with a great natural fit when wearing just a tee shirt underneath, but it's roomy enough layer underneath it (100 weight fleece or heavy thermals ). A 300 weight fleece would be a tight fit and I wouldn't try to use this piece as part of my system if I was going to be inactive and it was cold enough to need thick fleece. The Gamma MX is a very thin piece but surprisingly warm and is superb as cutting down the wind, but it is def. NOT wind or waterproof. I'm a photojournalist so I'm outside a lot in all kinds of weather and always on the run and the Gamma MX is on or near me at all times. During the fall when I was shooting outdoors sporting events , meaning I was relatively stationary and inactive, I was very pleased with how it cut down the wind and maintained warmth on days where wind chill dipped temps down around freezing. It wasn't toasty but all that was missing a shell and I would've been golden. The four main pockets are very convenient. The styling is nice. It performs as intended. Great Jacket, very versatile.

So far this has been a bomber jacket. I have climbed, camped, and biked in it and wear it around town. It is not the warmest jacket around, but that's what layering is for. It has been almost completely waterproof for me, living here in the Oregon winter, and significantly cuts down on the drafty weather. My only complaints is that it could be a warmer fleece and I wish it would block out a little bit more of the wind. We will see about its water resistance in a month or two.

Excellent construction, marvelous technical piece for whatever it is that you use it for. Versatile, veritably windproof, great at shedding rain and snow. I've used it for: winter biking, cross-country skiing, snowshoeing, hiking the Rockies, pretty much anything you throw at it. Stretches like mad, super-comfortable athletic fit (order a size up for layering a down sweater underneath). Looks BOSS. Convenient pocket for stashing gear, food, doobie-making equipment. Lightweight, stashes easily. Very abrasion-resistant (go ahead, fall down that gully). cons: The Fabric. Not very warm, as the fleece interior pills very quickly (mine is only 2 years old and has lost all of its heat retention). Naturally, this is not intended to be an insulating piece, but what insulation it does provide did not last long in my jacket (currently being considered by Arc'teryx as warranty return). In the end, the fleece is surplus and just a weight-adder. A minor gripe: no hood-and-loop closures at the wrist to block wind even better, but at least the tapering is pretty tight. I am considering switching it for something from the Sigma line (SV , AR)?

I have had my Gamma MX for over a year now and have worn it almost everyday since I have got it. It takes a beating and has worn very nicely. It packs very small and holds the weather off short of a deluge. I have several other softshells and they collect dust in my closet. I also own other Arc'Teryx products and this one gets the most use by far.

The only reason I returned the jacket is because my husband wanted a leather jacket instead. I love my jacket that I purchased last year which is also the Gamma. Thanks.

I would give it 5 stars if I was a climber which I'm not, but the MX (mixed use) jacket is supposed to be an all around jacket, and it is, but with long sleeves. It does shed water and dry out brilliantly as well as block the wind. It's great for moving around while backpacking and in camp is really nice when used in tandem with a wool base layer. And, of course it helps that it looks really sharp at the bars after a day of shredding pow.

Arc'teryx makes the best fitting apparel for me at 6'2" and 185 lbs., along with 66 North Iceland. An Arc'teryx large is a perfect fit, especially with their longer sleeves than many other brands (a certain "hardwear" company specifically). Adding this MX, I now have a full Gamma lineup with the now discontinued LT, and a couple SV's. Even though this one is manufactured across the Pacific, it still seems to have the great Arc'teryx quality in construction. I like the garbanzo color I got on sale as well, it looks like khaki to me. Best for cool conditions in the 45-55 range. Very windproof, thin and light. I've worn it in a drizzle and water beads well. I haven't had a chance to try it in anything cooler yet.

The first thing I like about the jacket is its nice lines, it looks hot. It is warm but it doesn't over heat. I wore it in about 50'F weather and it held up perfectly. The big pockets were a big help in finding loose items and the long pocket zippers allow you to get a gloved hand in so you don't have to fumble taking off thinner gloves. It would also work great as a mid layer under a hard shell, too. Great function and great looks.

Tried a couple of other softshells (both Windstopper and Polartec Powershield) but the fit of this jacket is just the best! The sleeves are actually quite long for me (I'm 6'0" and got a Large), but that will prove it's value when cycling (I'm Dutch) or iceclimbing. Really like the fabric, as it is incredibly stretchy and allows great movement. Furthermore, Arc'teryx pays so very much attention to details, which is reflected in the finishing of e.g. the zippers and the lining of the jacket.

This is my favorite piece of clothing, very warm for its weight and sheds rain well. Packs so small you don't even know it's in your pack.

I've had my MX for about 2 years now, and I can honestly say that it was probably one of my best outerwear purchases of all time. It's great without an insulating layer down to about freezing (if you're moving around) and can go a bit lower with some light insulation. Practically wind proof up to about 20 mph w/o insulation. Close to rain proof when the DWR coating is in good condition, but wets out if you haven't reapplied the coating in a while. The fabric is great for wear resistance - sliding on rocks, dirt, tree branches, etc. leaves no cuts or abrasions. The first thing that wore out were the cuffs. The elastic isn't so stretchy anymore, and they have shredded a good amount at the edges. The back of the jacket will also show some wear (turns a little lighter blackish gray) from sitting against rough objects. The interior lining is also de-laminating a little bit around the seam edges. But this is after nearly two years of almost daily use, so what can you expect? If you're in the market for a soft shell with no peer, look no further than this jacket.

The shell is light-weight, but highly wind resistant. Numerous pockets, The collar when zipped is extremely comfortable. Excellent value.

This jacket is a good compliment to my Beta AR. Its four pockets also make it an excellent travel jacket as well as on the mountain. If you have a storm jacket, you can cover everything else the weather may throw at you with this one.

Excellent soft-shell. The only people who complain about this are people who don’t understand the concept of the soft-shell. I used to pray to the Mountain Hardwear gods. But I sold my MH Alchemy jacket and bout this. I’ll never look back. Excellent fit. Classy look. Excellent function. I couldn’t be happier. Of course I bought mine used for half the price, so I might feel a little different if I’d paid $300.

I recently bought this jacket but sent it back and went with a size larger and it worked out great for wearing the covert hoody underneath.I love most Arc'teryx clothing but found i need to get a larger size since i need the extra room and it's a little form fitting on some of their softshells.I used it skiing in Lake Tahoe and it worked out great!I suggest going a size larger when you spend money on something you will have forever!!

Super versatile, breathes pretty good and gives great weather protection. I do not recommend a light color as it gets dirty fast. It feels like your favorite shirt or sweatshirt, stretches like Stretch Armstrong too! Cant go wrong with this. Very trim sizing, wish it was a bit of a longer cut for my tall lanky frame.

I usually wear a size medium in jackets and shirts. But in the Gamma MX I wear a size large and it was still rather tight. The arms are very snug. If you like to wear a long sleeve shirt under your jacket, forget it. The jacket is made very well like everything Arcteryx makes. I returned it for the slightly more expensive Stingray which is absolutely a great all around jacket.

I've always wanted to get a Gamma MX, but never was willing to pony up the dough. I finally broke down and got one. As much as I hate writing anything negative about Arc'teryx, I must admit I'm not too fond of the fit of this jacket. I got myself a medium. The sleeves are perfect for me, but the body of the jacket is pretty short. I know the cut is tailored for climbing, so it's probably perfect if you're actually using it for climbing. I use mine for just about everything, but I always find myself pulling down on the bottom of the jacket, because it feels like it's always riding up on me. Like I said before, I love the stretchy Polartec fabric, water resistance, breathability, and everything else about the jacket - I just wish they'd cut the body a wee bit longer.

This jacket wasn't what i expected. I was hoping for something as warm as the easy rider, however this jacket is much thinner and lighter. It has ample pockets, but requires extra layers for outdoor activities. I believe Arc'teryx made this for hiking/climbing etc, whereas I was looking for a warm softshell to wear skiing under a shell. Looks good and feels good, just wasn't as warm as I hoped

Regarding the fit, it's an athletic fit, so it looks great, but you can't wear layers underneath. I'm 5'8 and 165, and the jacket fits perfect over a long-sleeve t-shirt or thin sweater. Great cut allows for full ROM with the arms -- 100% windproof -- it'll keep you from being cold but won't necessarily make you warm, probably because you can't layer underneath. I still don't know if I'd recommend dropping so much money on this jacket -- I would have expected more for so much.

It's a very nice jacket!

This is a GREAT jacket and can be used over 90% of days skiing. Adequate wind protection, but needs help on the most cold and windy days. Fit is top notch and has excellent breathability. I'd buy it again in a heartbeat.
