Product Details
The Arc'teryx Proton Hoody Men’s is an active insulation layer designed for high-output use in cold conditions. It’s built for breathability and temperature regulation rather than static warmth, making it ideal for moving fast in the mountains. This hoody excels during hiking, climbing, ski touring, and mountaineering, where managing moisture and heat buildup is critical. It stays comfortable during sustained movement while still offering warmth when conditions cool. Unlike traditional insulated jackets, the Proton Hoody is designed to be worn during activity. It’s often layered under a Gore-Tex shell in harsh weather or worn as an outer layer in dry conditions.
