Everybody!!! come see how good I look!

Couldn't decide between this and the Venta SV, so I ordered them both to try them in person with the idea to give up the loser. Bad idea. With Arc'teryx there are no losers and I have to explain to my wife why I need both these jackets.

There are so many things to love about this jacket. Despite all the technical features I have to start out by saying just how good it looks. I have the "nightshade" and both the grey and the blue of this jacket are darker than what is shown here, but look super sharp. If anything bad could be said about the look of this jacket, it is that the logo is printed and not embroidered. You give up a little in weather protection with not having a membrane like windstopper in the Venta SV, but the gains you get in breathabilty are noticeable - pit zips not included because they aren't necessary. The outside pockets are plentiful and definitely adequate but I do always like an inner zip pocket as well which is missing on this jacket. The cuffs are stretchy and slide on nicely. Sometimes I prefer being able to adjust the cuffs, but being able to just throw the jacket on and not fuss with velcro is also nice. This jacket isn't intended for as severe weather as the Venta SV, but still handles a wide range of conditions and is preferable in many of them. It also works better as a mid layer if you every wanted to throw a shell over it, as it isn't cut as long in the rear and has no hood.

6'3" 275

I've had two unsolicited comments on weight loss after donning this jacket. I'm long in the torso, and the xxl fits great - hip length and enough front length not to ride up. I walk a couple miles every morning, and regularly reach for the Gamma, over a mock turtle if the temps are under 50 or short-sleeve polo if the temps are above 50. Material is non-bulky and nice to touch. I had my doubts, but worth the price.

The Best is even better

I own a few MXs and this latest version is a significant improvement over the 2010 version. The Fortius 2.0 material makes the jacket much better in weather resistance yet it's somehow smoother to the touch and moves even better with the body. Impressive materials here. Other than the material, the 2011 version is slightly longer thus offering better body coverage and warmth retention, all without becoming bulky or awkward. Whoever said "if it ain't broke don't fix it" needs to listen to the folks at Arcteryx. The MX is now a true year-round or 3 season jacket with no weaknesses.

Awesome Jacket

I absolutely love this jacket. It is extremely comfortable and very versatile. This reminds me again and again why I love Arc'Teryx.

The secret (or not so secret) to blocking the wind. -Ha

I am partial to Arc'teryx because of their always perfect workmanship and supreme fit for my build. (6'3" & 190 lbs requiring long arms, broader shoulders, and a smaller waist) This softshell is no exception.

For this Jacket I had one complaint until I figured it out:
I was unimpressed with its inability to block wind sometimes more than others. In fact for the high price, I was somewhat annoyed. Then I realized, like an idiot, that the times it wasn't blocking wind well were the times I had my hands in my pockets of the jacket, which meant I had some of the zippers unzipped. Since this jacket is designed to regulate temperature so well, it appears that every zipper provides venting. Thus, with zippers down, the wind gets in, and zippers up, wind is blocked entirely. I don't consider this a design flaw because the vents are ideal when used properly.
Anyway, hopefully none of you "gear connoisseurs" will find yourselves annoyed from a user error such as mine, but I HAVE read reviews stating a dissatisfaction on wind block performance so I thought I would share my novel discovery. Ha ha.

For this jacket, I bought XL. If I ever go L, it usually has to be a "hard to find" L Long for my longer arms, but on this, the XL gives plenty of room in the arms & is not baggy at the waist (which seems to often be the trade off with an XL vs L). Hopefully that helps.

Doesn't get any better

This is the most comfortable soft shell you'll ever put on hands down. If you're able to shell out a little extra for one go for it. You won't regret it. I got one in 2011 so not sure about durability but given the Arc'teryx name I'm going to assume it will last a very long time.

Super nice lite jacket

This is my first experience with Arc'teryx products I have always heard good things but had never tried their products. I must say this light jacket lives up to their reputation very well built nice weight and a nice color selection. I went with the blue and at 6'5" the xxl gave me some room to have a mid layer as well certainly the best technical jacket I own yet still looks great around town. I will be trying more items from Arc'teryx in the future.

Posted on

I am looking for a softshell that would be used backcountry ski touring and a mix of around town wear. I originally looked at and have purchased the Venta AR (just received, have yet to wear it as intended). My interest in the Venta AR was for windproof properties, now I am reconsidering my decision on the Venta AR, in lieu of the breathability of the Gamma MX and more of an ability to use it as a mid layer when conditions worsen. Any thoughts would be greatly appreciated.

Responded on

I've had a Gamma MX for five years or so, no hood. I wear it all the time on and off the slopes, I love this thing. With a base layer and some kind of mid layer (mostly Delta LT 1/4 Zip), the Gamma MX has taken me down into the 20s no problem. When the weather turns wet, I throw on my Sabre SV over the Gamma MX. It all keeps me warm and dry. Its a great jacket.

Responded on

The Gamma MX is definitely more breathable (I have the old polartec version); however, you do sacrifice some of the windproofness (and waterproofness) that the Venta offers. As far as using the MX as a midlayer, I have found that my MX under my Alpha SV is great for sealing out weather; however, the MX does not offer much insulation for keeping you warm. I would objectively rate it the equivalent warming power as about a 100wt fleece. It does layer well due to the short cut of the garment.

Not as useful as I expected.....

I bought this thinking it would be handy in most conditions in the 50 degree range.... If there is any wind it cuts right through.... Pretty expensive for what you get....

I used it in the same weather conditions and mine blocks the wind pretty well. I have the Polartec version. I bought it for

Arc'teryx is on to something...

Arc'teryx is on to something here. This is the best jacket your money can buy. Yeah - it's expensive, but worth every dime. I'll admit I haven't put it through any extended field testing. The caveat to that is that I live in New Hampshire. In the month I've owned it, it's seen rain, snow, and 60 degree weather. If you can expect /anything/ from a softshell - this meets every expectation. Wind proof. Water"proof". And it breathes better than any jacket I've ever owned. Buy it.

Great Jacket

Everyone comments on how awesome this jacket looks. It's warm, light and stays clean. The first week I had the jacket, a drink leaked all over me. I was scared for a minute, but then all the liquid just rolled right off!

All the pockets are great and keep my phone close and dry.

When it's windy (and below 30 degrees), it can get a little chilly, but that was expected with a jacket of this material. I usually only wear a t-shirt underneath because I bought the jacket a little smaller than I normally would; I like the tighter fit.

I'd buy it again!

Updated Gamma MX with Fortius

I just got this piece in the mail today, and immediately you can tell a difference to the old one. I have last years model in my closet, so this comparison was pretty easy.
Firstly, the Fortius 2.0 feels better in my opinion than the old Polartec model. They claim this year is lighter, but it actually feels heavier to me... In a good way. The jacket now feels slightly. More substantial than the previous model, but by no means heavy.
The cut seems to have changed a bit too, as both my models are XL but they fit slightly differently. The new model has a slightly looser cut when compared to the old one, and is a bit longer in the front. Overall all I would describe the Fortius model as just a bit more relaxed fit compared to the old. I am between a large and extra large, and the new model made strongly consider trying on a large when compared to the fit of the old XL.
The pocket and zipper setup is the same, but the cuffs are now the same material as the jacket, and not as much a tight squeeze into to. Sleeve length is the same as well.
. Overall, the jacket feels like an improvement in materials but makes me question my size a bit. I'd say it is cut more like shell it is designed to beand less of a mid layer fit that last years could be used as. I would definitely not shy away from this, even if you have an older model... The Fortius is that nice feeling. I would also add that the colors are spot on unlike some previous years, the nightshade looks exactly as portrayed.

Responded on

I wanted to update my review, by adding that this version is definitely an improvement on the polartec model. I have worn mine for a month now, and think it is every bit as good as the old model if not a little bit better. The fit is a little longer, so it fits my 6'3" build better than the old model. The material is very sturdy feeling, and seems to block up to a moderate wind very well. I have worn it in the 40's with just a tee shirt and been just fine. When a sweat does get worked up, the fortius dissipates it quickly. I looked at the AR and LT models, but can't think of any reason why the MX can't do a reasonably good job at either of those jackets jobs. It's worth the money in my book, I will likely ski in it as a shell and possibly even use it as a mid layer when it dips to 30 and lower.

Is the Arc'teryx Gamma too warm for 45-55 degrees? (football spectator)

Responded on

No, it should be perfect if you're watching. Wear a L/S tee or baselayer and you should be fine, even if it's windy. A few choice beverages will make you bullet-proof. haha

...and the spills will roll right off the beverage resistant face fabric. This jacket is great for spectating, although designed for hockey it will be excellent for american football.

Ready for warmth under pressure?

This is a great Jacket for the Northwest. Warm, snuggly fleece, tough as nails construction. It breaths well and sheds my sweat great. I wear a large (5'10'' 205 lbs muscular build) and the sleeves are about an inch too long...other than the sleeves it fits extremely well. If its particularly cold out I throw on my Arc'teryx Accelero Jacket underneath this Gamma and that seems to be a pair that can't be beat. I work for the Forest Service maintaining trails and this puppy stands up to hard labor like a champ.

Excellent jac. I found mine on Ebay for 129$...check that out if you can.

I am looking for a softshell jacket for backpacking in temperatures from 35-55 deg f. I am 6' 230lb. I was wondering if I should go for the xl.

Responded on

You should measure your chest and check arcteryx sizing chart. THere is a bit of stretch with the fabric. Judging by your size an XL should fit but you should double check just to make sure.

Best Answer Responded on

I am 205 lbs and 5'10'' with a muscular build. I wear a Large and it fits me like a glove (the sleeves are a bit long). My brother is 6' 205 lbs with a extremely muscular build and it fits him quite well. If you have a little extra weight in the mid section I would go for the XL. If you are fairly trim around the tummy I would go for the Large.
