The Men's Patagonia R1 Air Fleece Zip-Neck Pullover is a quarter zip fleece for layering up and heading into the wilderness. Cool weather is no problem when you come prepared with a light yet breathable fleece. The 100% recycled polyester features hollow-core yarns to wick sweat and dry quickly, combined with a zigzag-knit pattern to increase airflow and reduce bulk, and finished with a chest pocket, where you can stash a small snack, lip balm, or ID.
