Patagonia Men's R1 Air Zip Neck Black / Large

From alpine starts to cool-weather trail runs, the Patagonia Men’s R1 Air Zip Neck offers breathable warmth and technical versatility in a trim, movement-friendly design. Available in Black, Dried Vanilla, and Pelican, each colorway brings understated style to this high-performance layer. The lightweight fleece is made from 100% recycled polyester and features a zigzag texture that enhances airflow and moisture wicking during high-output activities. A deep front zipper allows for easy venting, while the off-shoulder seams prevent chafing under pack straps. Soft next-to-skin comfort and a slim fit make this zip neck ideal for layering or wearing on its own during active pursuits. Whether climbing, hiking, or skiing, it keeps you warm and dry without slowing you down.
