The Patagonia R1 Air Vest is a lightweight technical fleece layer built for breathable warmth in cool conditions. Designed as a core-warmer, it adds insulation where you need it most while keeping your shoulders and arms free.
Made from 100% recycled polyester fabric, the R1 Air Vest is highly breathable, quick-drying, and comfortable during active use. Its efficient warmth-to-weight design makes it easy to wear on its own in mild weather or layer under a shell when conditions change.
