R1 Air Vest – Men's

For high-output days in cool weather, the R1 Air Vest is our go-to insulating vest for runners, hikers, and skiers who run hot. Hollow-core yarns in a zigzag knit move moisture and dump heat fast, while off-shoulder seams keep pack straps from rubbing under a hydration vest.

• Hollow-core yarns trap core warmth without holding heat, so you stay comfortable when effort ramps up on cool mornings
• Zigzag jacquard knit in 100% recycled polyester fleece boosts airflow, dries fast, and stuffs down small in a pack or pocket
• Off-shoulder seams remove pressure points and chafing, so it wears comfortably under a hydration vest or pack all day
• Vest cut leaves your arms completely free for climbing, technical approaches, and ski transitions
• Made in a Fair Trade Certified factory, available in Black and Smolder Blue, sizes S–XL
