The Patagonia Men's R1 Air Fleece Crew is a lightweight, highly breathable, and quick-drying technical fleece built for high-exertion activities in cool conditions. Crafted from 100% recycled polyester jacquard fleece with hollow-core yarns, it features a unique zigzag-knit pattern that maximizes airflow and minimizes bulk for optimal temperature regulation. Off-shoulder seams sit comfortably under backpack straps to prevent chafing, while quick-drying woven binding on the cuffs and back hem offers a streamlined fit. Complete with a zippered left-chest pocket for securing small essentials, this technical crewneck delivers versatile layering performance on the trail.
