R1 Air Zip Neck Midlayer – Men's

When the trail demands hard effort in cool air, the R1 Air Zip Neck is our go-to midlayer for runners and hikers who run hot. Hollow-core recycled polyester in a zigzag-knit construction moves moisture fast and vents heat before it builds, while off-shoulder seams stay clean under pack straps all day.

• Hollow-core recycled polyester jacquard fleece wicks sweat fast and dries quickly without trapping heat against your skin
• Zigzag-knit construction opens up airflow where you need it most and compresses small for easy stashing in a vest pocket
• Off-shoulder seam placement eliminates hot spots and pressure points under pack straps during long carries
• Quarter-zip lets you dial ventilation on the fly — crack it open on climbs, seal it back up on descents
• Made in a Fair Trade Certified™ factory; zippered left-chest pocket secures small essentials without bounce
