Arc'teryx Men's Proton AR Hoody Black - Small

An all-round, versatile hooded jacket created to balance warmth and airflow, the Proton AR Hoody is the warmest option in the Proton series. Designed to perform both as a softshell outer layer and as a mid-layer under a waterproof shell, it leverages advanced material technologies that provide thermal protection while allowing air to pass freely in and out. This helps prevent vapor accumulation and allows the Proton AR to regulate comfort over a wide range of temperatures and conditions.
