The Patagonia R1 Air Jacket is a lightweight highly breathable technical fleece built for cool weather activities. It balances steady warmth with excellent airflow and moisture management, making it ideal for high output use as a midlayer or standalone piece.

• Constructed from 100 percent recycled polyester jacquard fleece featuring hollow core yarns that wick moisture and dry quickly while retaining consistent warmth.
• Zigzag knit pattern increases airflow and minimizes bulk for breathable lightweight and compressible performance.
• Full length center front zipper enables easy on and off and quick ventilation adjustment.
• Slim fit design layers smoothly over baselayers and under outer shells without excess fabric.
• Offset shoulder seams sit comfortably under pack straps and harnesses without causing irritation.
• One zippered left chest pocket secures small essentials alongside two front pockets with streamlined low profile zippers.
• Quick drying woven binding reinforces cuffs and back hem for improved fit and long lasting durability.
• Fabric is bluesign approved and the jacket is made in a Fair Trade Certified factory supporting safe working conditions and community benefit premiums.
