Mountain-Ready Softshell.

The men’s GAMMA MX Jacket is a breathable and wind-resistant softshell perfect for heightened mobility during alpine endeavors in mixed seasonal weather. It’s constructed with Fortius 2.0 textile for comfort and stretch while providing the lightweight insulation suitable for frosty missions. A durable and highly wind-resistant face sheds moisture thanks to a DWR finish, while a light fleece backing seals in your core warmth. Articulated elbows and no-lift gusseted underarms guarantee premium maneuverability when you’re hiking or ski touring. The laminated drop back hem adjusts with a drawcord, allowing you to seal out chilly updrafts. Dual hand and chest pocket, along with a laminated bicep pocket, provide ample storage for your map, tools, and phone.
