Arc'teryx Men's Gamma Jacket

The Gamma Jacket is built for high-output mountain activities, providing essential wind and water resistance across rugged terrain. Its breathable fabric ensures comfort during intense uphill climbs, acting as a protective shield without causing overheating on the final push to the summit. Engineered with high-stretch materials and articulated patterning, this jacket allows for unrestricted overhead movement during technical scrambles. The exceptionally durable face fabric is specifically designed to withstand abrasion from rock and rough surfaces, ensuring long-lasting performance in the backcountry. This version incorporates increased recycled content and a PFAS-free DWR treatment for sustainable protection. Dual zippered chest pockets offer expanded storage, while refined design lines provide a more streamlined, modern fit.
