Arc'teryx Proton AR Hoody

The Proton AR Hoody is designed to provide warm, air-permeable, self-regulating insulation for versatile and all-round climbing performance. As a mid-layer, the Proton AR Hoody uses materials that provide thermal insulation but an air permeability that prevents moisture accumulation and overheating. As an outer layer, the jacket’s shell material is abrasion-resistant, with a DWR finish to repel light rain and snow, and a hydrophobic synthetic insulation that is quick drying and retains warmth, even when wet. The Proton AR Hoody is the warmest jacket in the Proton range so is ideal for those who feel the cold.
