Arcteryx Mens Gamma MX Hoody Poseidon

Season:2016

The brilliant and incredibly versatile Gamma MX Hoody is one of the best mountain softshells available. It performs superbly across a wide range of conditions, fits beautifully and looks fantastic! 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 mix 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 all mountain softshells.

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.
