R1 Air Zip Neck Midlayer – Men's

When the temperature drops but the effort stays high, the R1 Air Zip Neck is our go-to midlayer for trail runners and hikers who run hot. Hollow-core recycled polyester in a zigzag-knit construction dumps heat fast and moves moisture before it slows you down, while off-shoulder seams stay clean under pack straps all day.

• Hollow-core recycled polyester jacquard fleece wicks and dries fast — manages heat output without sacrificing warmth on stops
• Zigzag-knit construction maximizes airflow through the fabric and packs down small enough to stuff in a vest pocket
• Off-shoulder seams eliminate pressure points and hot spots during long carries with a loaded pack
• Quarter-zip lets you dial ventilation on the fly — crack it open on climbs, close it down when you stop or descend
• Made in a Fair Trade Certified factory; zippered left-chest pocket secures small essentials without bulk — available in Black, Old Growth Green, Summit Blue, Pelican, and Oar Tan
