The Patagonia Women's R1 Air Fleece Vest delivers lightweight warmth and breathable performance for cool-weather adventures. Its 100% recycled polyester jacquard fleece uses hollow-core yarns to wick moisture, dry quickly, and promote airflow during active pursuits. A zigzag-knit pattern increases breathability while keeping the vest lightweight and compressible for easy layering. The slim fit and full-zip design provide warmth around the core without restricting movement through the shoulders and arms. Offset-shoulder seams sit comfortably beneath pack straps, making this vest a practical choice for hiking and other outdoor activities. Multiple zippered pockets provide convenient storage without adding unnecessary bulk. Made in a Fair Trade Certified factory, this vest combines technical performance with responsible construction.
