Arc'teryx Gamma MX Jacket -

The Arc'teryx Women's Gamma MX Jacket is a sleek, stylish mid-layer fleece that excels at adding versatility to your layering system. It also excels as an everyday soft shell. Sporting an athletic, hip-length fit with anatomical shaping, articulated elbows and gusseted underarms, the Gamma MX Hoody will fit you like a glove and offers full coverage (also like a glove). It functions superbly as an insulating layer on mountain expeditions, or on a trip to the petting zoo in the fall. Here's a tip: if you pretend you're interested in buying a dog, going to a breeder is a cheap way to play with a pile of puppies (like an adorable, free petting zoo).

Arc'teryx Gamma MX Jacket Reviews:

Positive Reviews:

I had the previous version of this jacket, so I knew that it was a lightweight softshell with little insulation when I ordered it. This is a very nice update from the previous version. I like the fabric better. This jacket is just what I wanted. I wasn't too sure when I ordered the Bondi Blue, so I ordered a black one just in case, but I kept the blue as it's a great color. This is not going to be my primary jacket, but I like to have a variety of jackets--one for every purpose and weather condition (ultra lightweight, lightweight, Gore-Tex, Windstopper, softshell, warm synthetic insulation, down, etc.). This one should see use year round, although only in winter with layers for active pursuits.

Negative Reviews:

I have the Arcteryx Atom SV hoody and absolutely love it. This jacket appears more sleek and modern looking in the photo than it is in reality. The fabric is THIN, REALLY THIN as in no insulation. This is a very pricey piece and I was disappointed in the unlined pockets - they are literally netting - no warm fabric. Although I would say that Arcteryx is top of the line when it comes to outerwear, I really didn't care for this jacket for day to day wear. I currently have a NF Apex Bionic that is much more comfortable (although not as well-made). I am 5'7"/125 and an athlete - a small was much looser than I was hoping for in the torso. I live in northern CA and was looking for a softshell that I could wear on a regular basis. Bottom line for me is that I didn't love it so I returned it.

Neutral Reviews:

The new Fortius fabric seemed great. I loved the feel and the weight of the jacket, it was soft and felt good but the cut was wrong for my body. Arc'teryx's smalls have always fit my body very well, (5'4-135lb) the athletic, next to skin, trim and relaxed had always fit me, but this jacket didn't. My main problem was that it was built too busty. I had too much space up top which resulted in a strange and unattractive fit. I don't know if i just got a incorrectly cut jacket or if they are all like that.
