Gamma MX Jacket Men's
Description
Created for the dynamic demands of alpine travel, the Gamma MX Jacket is a proven performer. Made from our Fortius 2.0 fabric, it provides midweight insulation, resists wind and repels water, breathes, and delivers exceptional durability. Built to handle everything from ice climbing to fall hikes, its articulated patterning and stretch combine for freedom of movement, and the regular fit allows room for light layers.
What's been updated: Updated with a PFAS-free FC0 DWR (Durable Water Repellent) treatment and a roomier regular fit for expanded layering options.
