Perfect light weight jacket
October 22, 2011

I like this jacket even though it wasn't quite what I was expecting. I ordered this after trying on the Gamma MX hoodie but didn't notice that this version is light weight and the hoodie is medium weight. I'm keeping this one and ordering the hoodie version also. I got the medium which is my typical jacket size. The fit is athletic but not tight - perfect overall. The materials are top notch - this is an expensive jacket but it is worth it. Perfect fall jacket.

Pros: Great design, Build quality, Performance

Awesome feel
January 16, 2010

Thus far my opinion of this jacket is highly favorable. The only thing I'm not decided upon is if the warmth matches up to the high price. Although, that might sound bad, the jacket is extremely light and almost paper thin which, for me, makes up for that. (Don't get me wrong it's still just as warm as TNF) Another thing to add is that it fits amazingly well as a layering piece. In fact, I don't think I've ever had anything that feels this good under something bulkier, such as a fleece. The biggest con to this jacket is the price, but if you want a quality product and have the money to spend you won't go wrong buying this jacket.

Great quality but poor fit for me.
January 16, 2010

I was a bit disappointed with fit compared to my other Arcteryx jackets. The quality is excellent as I expected. My Venta AR fits much better. I am 6'2" and 227lbs.

Instantly my favorite everyday jacket
May 14, 2009

picked this jacket up 2 winters ago and dispute the cold winter in the NW, it easily became my daily jacket. Keeps me dry and warm when I need it, and even now during the spring I still throw it on when it looks cloudy. Also works good under a shell when I'm on the slopes. Fits great and looks just as good as the day I got it. A bit pricey, but if you got the $$, you should add this jacket to your outerwear line-up.

Unreal softshell
December 05, 2010

Absolutely one of the nicest lightweight softshell on the marktet. You definitely get what you pay for with the gamma mx. Only complaint is that the fit runs really small. In fact, I wanted to purchase a new one to replace my 2005 gamma mx and found the newer ones fit runs quite small. I recommend ordering a size up. Very athletic techinical fit.


Lighter than I thought
April 17, 2010

I thought it should be used in the winter like gamma sv, when I got it, I understood it is more suitable for spring and fall, I neglected its weight when I intend to buy it, But I am not disappointed about it, it 's so high quality and breathable. Most of all, it looks so stylish, I love this jacket.

Great Jacket!
August 26, 2007

I've had several Arteryx jackets and this one is extremely useful. It keeps you warmer than the Gamma SV (in my opinion), but lighter in wt. and longer in length. Highly recommend this jacket as well as Altrec as a retailer - they value customer svc


Great all around jacket
May 08, 2011

I have owned several Arc'Teryx products and this has to be one of the best. Great athletic fit, technically very functional, and a good balance of warmth, wind resistance, and light weight. If you're looking for a stand-alone warm jacket this might not be your best choice, but it's very good at what it's intended for - technical mountaineering. Like all Arc'teryx products it's very pricey. Is it worth the price? Only you can be the judge. As for me, the great fit and functionality help me get over the price issue.

Another Quality Arcteryx Jacket
January 18, 2012

This is, in my opinion, the best all purpose jacket on the market. The material is top drawer and the jacket is useful in a wide range of climates and activities - from chilly to warm. It blocks wind well, and will resist (but not repel) water - the jacket will eventually get damp and clammy in a downpour, but it can handle anything short of that with ease. What is really impressive about this jacket is its versatility - not only will it handle a range of climatic conditions, it can definitely handle backpacking, rock climbing, either as an outer layer in most conditions, or as a layer if it gets cold or rainy. It also looks great -- it can be worn in casual social environments as well as on the trail. The jacket is expensive, but you can basically give away all others with the exception of a rain shell - it is that good. Bottom line - best jacket you can buy. The Gamma MX Jacket will be in my pack on the Trek on Kilimanjaro June 2012.

versatile and functional
September 26, 2006

I bought this jacket to use as a bike commuting outer layer in Portland. It doesn't have a hood, which makes it easy to see back over your shoulder, and a soft warm collar to keep the wind out. It has more pockets than you know what to do with. The construction is excellent, it's lightweight, and packs down small. The overall fit is very snug.

high quality
February 07, 2010

from it's light weightiness to it's attention to detail (zipper action, etc.), very nice jacket. I also like that it does not have both the arcteryx symbol and arcteryx also spelled out (i.e., some of their other softshells), which is a bit overkill. But don't buy it unless you are in love with the style and it fits you great, too much $$. Remember, it is a splurge.


Gamma Jacket is Great
March 29, 2011

I heard a lot of great things about the Arc'Teryx Gamma jacket and it has lived up to those expectations. It is not intended to be a hard shell or to protect you from harsh weather but to be a comfortable and light Fall zip up -- or mid layer. The quality is top notch, as you would expect from Arc'Teryx. The size is athletic so, be mindful of that before purchasing.

Another great softshell from Arcteryx
August 16, 2011

I think I understand why Arcteryx makes so many jackets, particularly softshells. They try to cover the entire spectrum of breathability and warmth. In the case of the Gamma MX, it is made to breathe very well and provide moderate wind and water protection as well as lightly insulate. I also own the venta sv and the hyllus and I note some real differences. The venta is windproof and has a thicker fleece lining, so it is made for different activities than the gamma MX. The hyllus had a very thick fleece lining and moderate wind protection. I mention these differences in hope of aiding others in their selection of the right softshell. The gamma MX is an awesome softshell for aerobic activities. It also keeps out most of the wind and protects against a moderate amount of rain. If you aren't going to be moving around much or the weather is colder, or windier, or wetter, I would recommend the venta sv. As far as the Gamma MX is concerned, I love it! I got the lichen color and it looks great. I take an xl and like all other Arcteryx jackets, it makes me look cooler than I really am. I know some people don't like the cuffs because they aren't adjustable, but I kinda like them. The quality is first rate, which is Arcteryx is my favorite clothing company. If you have the money or can find it on sale, I would highly recommend this jacket.

Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost

finally showing some wear and tear
September 06, 2009

I purchased a black Gamma MX 5 years ago and this spring the edges, zippers, and inner lining are looking old. This has been an amazing jacket as it is unbelievably versatile. To some degree you can wear this almost year round in most conditions. My concern is now that Arcyterx has been bought out by Adidas? and made in China now, will the quality be the same as the BC built version? I guess time will tell

November 08, 2007

I've had the Gamma MX for two years now. What amazes me most is the range of motion. When the temperature drops, I have no problem playing golf in this jacket. The fit is outstanding.

February 12, 2007

My first softshell- I was talked into getting something breathable like this instead of bulky sweaters that get wet with sweat quickly. I looked around and chose this one (Mens). I was not disappointed. Wore it with wool long underwear underneath and a thin gore-tex shell on top and it was a great, breathable midlayer for skiing in total "whiteout." I didn't feel cold for a second- even on the lift! My one issue is with the fit, but your opinion may vary based on body type. I'll be specific to aid those with a similar problem: I am 5'8" tall 147lbs (thin for my height, but athletic build). My chest measures 38," so the "small" is recommended for me (the sleeves are just right also). My problem (as someone else mentioned) is in the length. The small comes down to my belt, but the short length makes it look like it's too small for me (I like the "form fitting" or "technical" look, but looking too small is not acceptable- and the length does this). This is a small problem, until I move my arms and my entire stomach is exposed to the elements. As a result, I got a medium, not a small. The sleeves bunch slightly, and there is some loose fabric on the sides, but these are slight problems so I love this size. It isn't a "tech" fit, but it "fits." If you are skinny like me you may need a size up- or you can "true" size it but you may find it problematic without an over layer to cover your belly. Actually, if you want to see how this jacket fits me, look at the video for this product (above). The model has one that fits him like the medium fits me. It looks good, but it's not a "tech" fit. Depends what you're looking for. You'll love this jacket once you choose the correct size. Also: The hooded version is a bit longer and so solves this problem if you want a true tech fit, but I personally don't like a hood on my softshell and another on my outer layer.

Great Jacket for Work and Play
December 16, 2010

For years, I've been wearing North Face and Mountain Hardwear products. And I they're both great. But this Arc'teryx jacket is a on another level. The cut is perfect, not too tight or too loose, and the material and stitching is nails. It's such a clean, great looking jacket that it's appropriate as part of a Northern California business casual outfit. Now, I've got to order the women's version for my wife.

I have beat the heck out of this jacket and it still looks great. No scuffs or rips. I am a medium in the Alpha SV and this jacket fits like a true medium.

Great Softshell
December 06, 2011

The 2011 Arc'teryx Gamma MX is definitely as good, if not better than last year's model. Instead of Polartec, it now uses a new fabric by Arc'teryx called Fortius. I've noticed it not only breathes better, but keeps you a little warmer when you need it. This jacket is the perfect all around soft-shell because of its light fleece and tall collar. Snow and rain just sheds right off. Add a shell on top and you have a good light mid-layer.

Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost

The Only Jacket you need
June 23, 2009

From a cool summers night watching the sunset on the Pacific Ocean skyline, to a brisk early morning, frosty grass hike in the alpine mtns to the warmth of the ski lodge sipping warm rum, this is the only breathable coat you will need. Warm, breathable, packable, and down right just cool to be seen in!


Best softshell
August 18, 2008

I've owned several softshells over the years, and this one remains the only one I wear pretty much all season long. I love this one so much, I also got one with hood. While, not trim fit, its size is slightly smaller than normal softshell, so if you want to layer, I would recommend ording 1 size up.


Best Jacket Yet
December 11, 2009

This is my 2nd jacket. After 5 years of wear I finally decided to "renew" my gear. The old one is now used only for son's scouts trips... still works well. I have done everything in this jacket... ski, bike, paragliding, hiking, running, cross country skiing. It is the best. Fits true to size but on a slimmer more fitted side. I am 6f1in 165lbs and fitted works really well for me - size M.

A great jacket
April 27, 2011

The Gamma MX jacket is all that it is advertised. The fit is perfect and sleek. The price is a litle high but the quality seems to be there. I would recommend the jacket without reservation.


What I have learnt to expect...
April 22, 2010

...from Arc'teryx gear, is also what this item delivered. Design and material that makes perfect sense, almost regardless what you intend to do with it (see all the other reviews on this item). Great look and quality. I will hike with it, run with it, ski with it, drive to work in it, buy groceries with it, etc, etc. It seems to run a bit smaller in size compared to other Arc'teryx gear I have, so I will get a larger one, but otherwise the exact same thing.

great jacket
February 28, 2007

Stylish. Range of motion is excellent. Well made. Breathes nicely. Get compliments on jacket all the time. When using in cold weather layering is key though.

Great looking jacket
June 05, 2011

This is one sharp looking jacket. The fit is only waist length and the wrist might be a little tight if you are a big fellow. I am 170 lbs 5'7" and the medium fits fine. The jacket is warm enough down to the 40s with a long sleeve T. No room for layering so if you want multiple layers go one size up. Wind block is excellent, I wear this to run when the weather gets cool and it is very comfortable.


Unimprovable jacket
November 07, 2010

Just what I was looking for in a technical jacket - weather resistant, athletic fit (I hate my Patagonia fleece softshell b/c it's so bloated in the waist), light weight, multiple pockets (although it needs an inside drop-in pocket), perfect length in the waist area and arms. I bought a medium (5"10", 170 lbs) and it's trim without being constricting. Also great for downtown - my wife's a fashion maiden and she even commented on its good looks. So expensive but worth it - I expect to get any years of service from it and will wear it all winter in the frozen tundra that is Minnesota (although not appropriate for being sedentary in wintery outdoors).

Outstanding design and function
January 09, 2007

Light weight and warm. I use it to go to work in New England area. Extremly sastified with style and performance.

Worth the money
November 25, 2009

I'm 5'-9", 170 lbs and I bought a medium Gamma MX. The fit is trim enough for layering under a hardshell and the stretch Polartech Powershield actually stretches. Be aware though that the sleeves fit snugly and at most you can wear two light layers under them, or a medium layer and a light fleece vest. Very tough outer layer has been snag and abrasion free. Highly recommended for wearing under a pack and harness.

I read a previous review from someone from minnesota that said this was the only jacket they required. This is most likely not the case for most people. I too reside in minnesota and the jacket is probably good down to 30F, 20 if sunny. That said it is not made for super low temps. This winter has been unseasonably warm so I have only been able to test the jacket down to 0F. Using it in a layering system works with a good windshell over it and a long sleeve shirt .underneath the gamma. i am 5'9" 155 lbs, a medium fits perfect. I usually buy 34/35 sleeves, and there is plenty of room there. All a round great jacket. Would prefer a little slimmer upper arms, but the space is probably the reason you can move so well in this jacket, so i shouldnt complain.

Pros: Build quality, Performance, Ease of use

Great Jacket
December 13, 2009

Fits really well. I'm 6"5" and skinny with long arms (usually need 36" sleeve length). I got the L and it wasn't baggy at all and the sleeves were perfect. The only thing is that the vermillion color is more orangey in color than it appears online.. like a dark rust color.

Warm, light, and versatile.

I like this light weight jacket, which is perfect for layering. I wear it in the city, in the ski lodge, in the parties... Size Large is perfect for 6 feet, 180 lbs. neck size 16 and sleeves 35! I got long arms and it is perfect!

Perfect Choice for a Soft Shell
December 03, 2010

I purchased this jacket in black for my husband for an early Christmas present. He is 5'11", 160 pounds, and the medium is a perfect fit. The jacket is very warm and windproof, but still very flexible, enabling free movement. Definitely a performance jacket and useful for all winter activities. Very highly recommend it!

best all around jacket
May 18, 2010

I have two years of use out of this jacket. Perfect for the fall as an outer layer. My main use for this jacket is while skinning with a single long sleeve layer underneath. At the top, throw on my shell and I'm good to go. This jacket breathes well, is nice and stretchy, and has tons of pockets. It is not waterproof or windproof, same as most soft shells.


This is the BOMB!
December 27, 2010

Great jacket...sizing is small so order the next size up. This jacket is bullet proof and the extra pockets are great. Very light weight but protection and comfort is outstanding. Stylish too!

Insanely Expensive - and Worth It
November 10, 2010

This is simply the best softshell I've ever found - and I've at least tried to sample them all! I have more than a little bit of a jacket fixation, and my closet is full of fancy softshells, driclimes, hardshells, and combo-shells. But it's almost always the Gamma MX I pull out when I'm actually going somewhere. Even within the stellar Arcteryx line (like the almost-as-nice but stiffer Epsilon line, which has fewer pockets), the Gamma MX is a cut above the rest. The fit is a little more athletic, the pockets are better placed, better sized, and more useful, the weather resistance is ideal, and - this is more important than I ever thought it would be - it's the softest and least "crunchy" of anything else out there. The "hand" of the fabric doesn;t sound like a big deal, but when you're planning (as I do) to spend this much money ONLY on a jacket that can do everything - from football games to mall trips to hardcore multi-night backpacking or ski touring - the comfort and quietness factors are actually pretty major (at least for me). The Gamma MX actually feels almost like a thick t-shirt: pliable, soft, slightly fuzzy on the inside, and completely silent. Add killer water resistance, wind resistance, breathability and pretty decent looks for a technical shell, and you've got a total winner. I have both the jacket version and the hoody version, and love both. My only suggestions for improvement would be to add a second sleeve or wrist zipper for quick-grab items and/or altimeter, and also a super-lightweight (mesh?) inside pocket. Other than that, it's hard to imagine improving on this one - but I'm sure Arcteryx will come up with something! P.S. Every once in a while they go on sale, and Altrec usually has the best deals.

Perfect combo of effectiveness and style
November 27, 2006

This jacket was purchased instead of a fleece for fair weather, but living in Syracuse, I've been caught on a couple cold days and have been pleasantly surprised. It holds up great to wind and temperatures down to about 30 degrees (yet breathes very well and i often wear it unzipped when its warm out). Purchasing this online, I was worried the about the fit, but being 5'11" and about 160 pounds with moderately long arms, a medium sized jacket fits me perfectly (perhaps i just got lucky). Furthermore, I have been had many positive comments about the looks of the jacket and am very happy that i don't wear the jacket of all my peers (N.Face). I feel this brand is a little too pricey to become trendy, but i can assure you once you've owned one piece, you'll be an addict.

Extremely high quality. Not the warmest soft shell.
September 30, 2009

This is an extremely nice jacket. The zippers are smooth and easy to use with one hand, the collar is tall and comfortable, and the jacket is extremely light. But the light weight comes at a cost: this jacket isn't the warmest soft shell out there. If you're in a windy, chilly place (I'm in Chicago), plan to need an extra layer under the shell.

My New Favorite
February 04, 2013

I have had a Gamma AR for about 5 years and it has been my go to jacket since the day I bought it. Since I purchased the Gamma MX jacket my AR hasn't seen the light of day. While I have only had the jacket for about three weeks, I anticipate a similar experience to my previous jacket. I love the snug fit and the articulated arms that allow for freedom of movement. I love the ability to go from outdoors to indoors and not having to remove the jacket. These jackets are great in a wide variety of climates, situations and activities. I can't recommend them enough.

Pros: Great design, Build quality, Lasts forever, Performance

lovely jacket
December 23, 2009

I love this jacket. Its super-functional and warm despite being really lightweight. I use it as a middle layer for snowboarding along with a base layer and an Arc'teryx shell and I'm comfortable in temps from the upper teens through upper 30's.

Awesome Jacket
January 02, 2011

As expected the fit and quality construction is first class! However, the material is very lightweight - lighter than I expected so I returned the jacket and bought the windstopper version. This jacket would be great for 3 season use - too lightweight in my opinion for winter unless conditions are mild and/or you are very active.


Perfect Midlayer

Outstanding softshell
December 05, 2010

I am 6' 3", 210 lbs. with an athletic build. I purchased an XL and the jacket fits like a "glove". I've purchased mostly Cloudveil products to this point and Gamma represents my first arcteryx purchase to date. Both Cloudveil and Arcteryx I find to be of similiar quality in workmanship (second to none) but the key destinguishing feature is the cut. The Gamma jacket fits almost like a second "skin" especially in the waist. My waist size is 34" and in most instances the Cloudveil products are a little baggy in the waist but the Gamma is cut to complement a more athletic build. I have received many compliments on the jacket and will most definately purchase other Arcteryx products in the future.

Excellent Jacket
December 04, 2006

I can't say enough about it. I own several softshells from other brands and this one is by far the best I own. You almost forget you're wearing it. Great Jacket!

The Gamma MX jacket is simply an amazing piece of garment. The construction and material are top notch, something you would expect from Arc'teryx. I bought this jacket to complement my Alpha LT as an insulation layer for wet and cold conditions, as well as an all purpose jacket for climbing and hiking to the crag. The medium fits perfect for my body frame (5'7"/150lbs) with just the right amount of room and little excess material.

Fantastic, versatile 3 season shell
October 22, 2011

I am 6' 2", 205 lbs. with long arms. Unless a manufacturer makes clothes in a tall size I almost always have to buy clothes a size larger to ensure the sleeves aren't too short. My job also requires I travel a lot and in any given week I could be in any part of the U.S. in any season so temperature versatility is a must. My criteria for a jacket is first fit, second versatile enough for 3 season wear (fall, winter, spring), third dressy enough that it can easily transition from the hiking trail to business casual travel wear, fourth accommodate a midlayer for colder days, and lastly sufficiently durable that it will last for years. After trying innumerable jackets over the last two years I was considering purchasing a custom made jacket before speaking with one of the staff at who recommended I try the Arcteryx Gamma MX. It fit perfectly from the moment I tried it on; the sleeves and the body were long enough and it fit perfectly through the waist, chest and shoulders, in other words it fit like a large tall, not like an XL regular which is usually long enough in the arms but too large in the body. It is extremely well articulated as it does not bind across the shoulders when you extend your arms. Best of all, even though it is relatively fitted it still has room for a mid-layer. After wearing it for the last two weeks in a variety of climates and conditions, I can say this jacket is the most comfortable, versatile jacket I have ever owned. It breathes extremely well making it comfortable in rapidly changing weather. I tend to run warm but you will want to consider a mid layer if the weather drops into the 30's or lower. All in all, it is expensive but given the quality and versatility, I think it is a great value and I would spend the money again in a heart beat.

My 2nd MX
October 25, 2012

I love my first MX jacket so much I literally wear it every chance i got. So I decided to buy another one 3 years later. The jacket design looks pretty much the same but I notice the fabric has improved. This MX jacket is slightly warmer but also slightly heavier. But just as good as the very first version. Plenty of pockets to store gadgets.

Another Quality Arcteryx Jacket
January 03, 2012

In the past I have found Arcteryx make high quality, sharp looking jackets and the Arcteryx Men's Gamma MX Jacket further ilustrates my past experience. I've had it for a few weeks, and already received a ton of compliments on it's sleek, sporty look (I got the Nighshade with the Blue Ray accents) It has kept me comfortable in tempertures 10-20 degrees F. That's considerably mild for winter in the midwest/plains. I'll try to update once the temperture drops, but I figure that is really the ideal temperture range for this particular jacket. I'm 5'8", 160 lbs. I generally wear a medium and this jacket is no different. Arcteryx may be more expensive than some other brands, but I've found you get what you pay for.

Pros: Great design, Build quality, Cons: Cost

Excellent lightweight shell
November 23, 2010

I'm really glad I bought this. It looks great, and the light weight belies the warmth it provides. The pockets on the sides are very handy, with large access through the zippers. Plus, there aren't too many pockets, making it easier to keep organized if you're carrying your phone, keys, ipod, etc. Perfect jacket for those spring and fall "thermocline days" when it's too cold in the morning and warm in the afternoon. Water also beads up nicely in light rain and drizzle.

One of the best light weight jackets you can buy!
June 23, 2006

Great material,incredable stiching, fantastic fit, just goes to show why Arc'teryx is number one.


Awesome Jacket!
February 03, 2010

This is a great light weight jacket. The construction is strong and athletic. I like the high collar and it provides warmth and blocks out the wind. Highly recommended!!

Expensive but nice
February 24, 2008

This is a very thin and light weight jacket. I've worn this on very windy days in the 40's F and it did a good job of blocking the wind but I wasn't exactly warm! While skiing I worn a base layer underneath with a shell over it and I was fine. I'm 5 ft 7 in 180 lbs and got the medium. Sure it makes me look fat but that is just motivation to get back in shape!

Love the fit and feel of this jacket. The material just feels super high quality. I almost don't want to beat it up climbing it looks so nice but that is what I bought it for. Love the design with the pockets that also double as vents.

Pros: Great design, Build quality, Performance, Great value, Cons: Cost

Love it
October 24, 2007

This jacket, like all Arc'teryx products are what I have come to expect from Arc'teryx. Light, functional, and above all, durable. This jacket is great for around campus and better when climbing.

Incredible Jacket.....very pleased!
November 14, 2006

I have several softshells from various brands and the Gamma Mx is hands down the best softshell I have ever owned. Sure, the others are functional but none are as nice fitting as this one; I almost forget that I am even wearing it. The endless amounts of pockets are very handy and the stretch is incredible. Note, it's not as warm as some other softshells, but it is very light. Layering is key. I am very pleased with this purchase.

Men's Gamma Mx jacket is by far one of the most reliable jackets I own. It keeps me warm on cold days and serves great as a mid-layer on the more frigid days. Overall this jacket has far exceeded my expectations!

Pros: Great design, Build quality, Ease of use

Great Softshell
December 14, 2009

Fits perfect - I am 6' 2", 185 lbs and the large is just right. Like the stretch which keeps it from riding up when reaching for my next pole plant or cold one. Good light jacket for spring skiing.

from SF

high price - excellent performance
April 12, 2011

This jacket is a typical Arcteryx product: high price but you get your moneys worth! It is quite lightweight and fits nicely (it runs a bit on the smaller side - L is perfect for 5'10" and 180lb). It will protect you from wind and rain in moderate temperature. I like the high collar and the reinforced left front pocket.


light warn and snug
November 20, 2009

I'm liking this jacket. It has a bit of a snug fit but should be. I'm 6" 190lbs and I ordered the L first but sent it back for the M. Will be using for hiking, camping, etc.

Light and wam

This jacket is light and can potentially block out all the wind. It is the same size as described. Polartec® Power Shield® fabric is breathable and keeps warm inside. Highly recommended!

All year around!
November 15, 2010

I took this soft-shell jack to Paris in winter, Fuji Mt in Spring, and ski trip in Mammoth at 40F sunny days! It all worked perfectly. Wearing it under the leather jacket in Paris during dry cold nights, it fitted fashionably into numerous occasions and protected me from the bone-chilling wind! And during 6 hours climb from the first station all the way to the 5th station in Fuji, it blocked out the elements from heat (foothill) to foggy coldness (half way). Skiing with this jacket in the perfect sunny day is awesome, keeping the body warm enough if you throw a wool base layer underneath. Not really a bomb shell jacket to protect you from powder snow, sub zero temperature (Celsius), or pouring rain. But a very well-built diverse jacket for year-round activity.

Pros: Great design, Build quality, Cons: Cost

Gamma MX
December 27, 2009

I love this jacket. It fits great over my Patagonia micro puff jacket. I am 6'5 and 185 pounds and the large is a perfect fit for me.

from east coast !!

love it!!
December 05, 2010

really good jacket for everyday activity, with the stretchy fabric, water reppelent and windstopper what else you can get, the only thing that i'm going to return it is the length of back that little bit too short for me otherwise i would keep it........

Must have to use it to fullest pontial to appreciate.
November 06, 2009

My work gave us Arc'teryx Gamma MX Jackets and I am glad I didn't pay for it. Upon pulling it from it's wrapping, I was initially disappointed as to how thin it appears. I am not a rock climber, backpacker, cross country skier, or mountaineer of any sorts and I am guessing this is who it was designed for. I am sure it has a specific purpose for those type of people but it doesn't really impress me just as a everyday jacket to wear for non athletic activities. especially for it's high price tag. If your just looking for a fall or spring jacket to wear with normal activities, I think there are many cheaper alternatives you can purchase. It does block the wind nicely and is relatively warm but most performance fleece jackets are. I gave it only 3 stars simply because it is probably more high tech than an inactive loaf like me could ever appreciate. When I heard we were getting them, I was excited but really don't see what all the rave is about.

Best Soft Shell on the Market
February 03, 2010

I just got this jacket after trying on all of the Arc'Teryx Soft Shells, and I can definitely say that the Gamma MX is my favorite by far. While it is not Gore windstopper material, it is much warmer than the windstopper soft shells and blocks about 90% of the wind. Which from living in San Francisco, Seattle, and LA is perfect. In fact I would say that if you live in either of those three areas this is the perfect jacket. I wear it walking the dog at night, traveling, and pretty much everywhere I go. I combine it with my Marmot Oracle jacket as a rain shell and I feel good to go. The fit is much more stream-lined than the other Arc'Teryx soft shells (which I like), and the wrists actually are fitted (which I also like). I'm 5'10", 195lbs, with broad shoulders and a large fits me pretty well.

I like this design so much. Of course the quality of Arc'teryx never betray my expectation, so I just choose one of those nicest jacket for hiking. It might be a bit expensive fr just hiking, so I think I should use it more often.

Love it for what it is
February 11, 2012

This is too form fitting (particularly in the arms) to be considered a jacket - it is more like a fist layer or a fashionable shirt jacket to wear over a t-shirt since a colared shirt does not fit very comforatably underneath. It is quite warm given its wieght (but not too warm to be warn as a shirt) and seems quite breatable - I just like lounging around the house in it or wearing it down to the pub. I am 5'10" tall and 185 lbs and am somewhat athletic, the medium fit me very well. I usually take a large in other Arcteryx products. Yes I would recommend to a friend but for what it is and not for what it isn't. Its a very conforatable garment and goes well with the Gamma MX pants. Be warm and look cool.

Pros: Great design, Build quality, Performance, Ease of use, comfort, Cons: Cost

awesome jacket
June 13, 2009

This jacket is by far the best soft shell I have ever worn!!!! Dries fast, keeps me warm, comfortable fit, plenty of storage space, and it is tough.

re: fit
October 04, 2006

I just wanted to comment on the fit: I'm 5'8, 160 lbs, 40" chest -- it's a perfect athletic fit, maybe a tad short at the waist -- but layering is difficult. BUT, as stated before, it's a great athletic fit.

Great Jacket!
December 19, 2006

After reading the reviews I decided I had to have this jacket and I was not disappointed! It fits great is easy to stuff in a backpack ready for unexpected weather change! I travel frequently and like taking this jacket along...just in case! Well done Arc'teryx!

forgot i had it on
September 22, 2006

I went camping this summer on the ocean in northern Germany and I lived in this thing the whole time. It is the only warm thing I take along on summer/mild-weather trips. It replaces sweater, vest, and windbreaker. You can leave it on all the time. I even slept in it during a cold rainy spell and it was a comfy as any pyjamas. It is right 24 hours a day in a wide temperature range. And I would ditto the other reviewer: It makes you loook and feel fit! By the way, once you get used to the wide Arcteryx collars you realize the advantages. The design is not an accident. The collars breathe well and do not constrict movement. You can always wear a turtleneck base layer if you are sensitive or skinny-necked like me. I am not into writing reviews but I am happy to make an exception and share my appreciation for this product.
