Gamma Mx Jacket Review

Delivering light weather protection breathable warmth and exceptional freedom of movement the gamma mx hoody is the solution.

Gamma mx jacket review.

From the outset the jacket failed to breath adequately when hiking uphill with or without a pack in cool weather. Gamma mx hoody alpine environments are dynamic. It is however a much more capable jacket than others that weigh the same or more. Based on my experiences with arc teryx see my review of the alpha sv jacket i decided on the gamma mx.

As the equipment coordinator for a search and rescue team i was faced with buying up to 50 fleece jackets for my team members. The gamma mx jacket has a verified weight of 21 ounces for a medium. A great value and super versatile. You need a softshell that works across the spectrum of changing outputs and shifting conditions.

The jacket features a micro fleece lining. While it isn t the most breathable or versatile jacket in our review we reach for it time and again when headed out for some winter fun. That being said when stuffed in a pack it takes up much more room than a lighter weight model so be prepared. This lining is very thin making is more ideal for high output activities and in warmer temperatures.

Arc teryx updated the fortius fabric in this 2020 model. It s also bulkier but the soft and flexible fabric expertly masks this. Stretchy comfortable stylish and warm. The gamma mx has more polyester than nylon making it softer to the touch and it has more elastane making it stretchier than the gamma lt.

The two jackets also have a different synthetic blend. The main difference between the gamma mx and the gamma lt is that the gamma mx has a fleece lined interior making it warmer but is slightly less breathable than the gamma lt.

The gamma mx hoody is a great jacket for all manner of winter missions from hiking and snowshoeing to ice mixed climbing and backcountry or cross country skiing.

I chose the hooded version for added warmth when a toque just won t do. Gamma mx hoody is an excellent variable condition jacket for just about any activity. Built from our fortius 2 0 fabric the gamma mx provides midweight insulation resists wind and water breathes and delivers exceptional durability. The gamma mx softshell jacket is arc teryx warmest gamma durable enough for the crag and weather resistant enough for fast changing mountain conditions.

The exterior soft shell material is wind and water resistant and it is very durable. My experiences with the gamma mx indicate that although the fit and design of this jacket is unparalleled the choice of fabric restricts the use of the jacket to light exertion activities where rain is unlikely. 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.
