Arc’teryx Men’s Gamma Mx Jacket

Created for the dynamic demands of alpine travel, the Gamma MX Jacket is a proven performer. Built from our Fortius™ 2.0 fabric, the Gamma MX provides midweight insulation, resists wind and water, breathes, and delivers exceptional durability. A go-to for climbers and backcountry adventurers, its articulated patterning and stretch combine for freedom of movement, crossover chest pockets are easily accessed while wearing a harness, and the trim fit and streamlined design give it a distinct Arc’teryx aesthetic.
