The Fortius 2.0 fabric used to make the Gamma MX is a membrane free, air permeable, four way stretch woven nylon, polyester and spandex laminated to mid loft 4 way stretch fleece. So it’s very stretchy, very breathable, very tough and very weather resistant making it just about the best mountain softshell available today.
Designed with active users in mind the Gamma MX has a close fitting athletic fit with long arms and gusseted underarm panels for completely unrestricted movement. Fitted with a helmet compatible StormHood which can be adjusted down to fit your head comfortably if you are not wearing your lid.
Finished off with the usual Arcteryx gorgeousness and featuring two fleece backed hand warmer pockets, two bellows chest pockets and a laminated sleeve pocket for all your essentials.
