Men's R1 Air Zip Neck Fleece – Men's

For high-output days when you need warmth without overheating, the R1 Air Zip Neck is our go-to midlayer for trail runners and hikers pushing hard in cool conditions. Hollow-core recycled polyester with a zigzag-knit pattern moves moisture fast and dumps heat before you bonk, while off-shoulder seams sit clean under pack straps.

• Hollow-core recycled polyester jacquard fleece wicks moisture quickly and dries fast without trapping heat
• Zigzag-knit construction increases airflow and compresses down small for easy packing
• Off-shoulder seams eliminate pressure points and hot spots under pack straps during long carries
• Quarter-zip lets you dial ventilation on the move — open up on climbs, close down on descents
• Made in a Fair Trade Certified™ factory; zippered left-chest pocket keeps small essentials secure
