R1 Air Vest – Men's

Built for high-output cold-weather activity where overheating is just as much a problem as the chill, the R1 Air Vest is our top pick for athletes who need core warmth without trapping heat. Hollow-core yarns in a zigzag jacquard knit move moisture fast and dump excess heat before it becomes sweat. Off-shoulder seams and a sleek profile mean it disappears under a pack or shell without a fight.

• 100% recycled polyester jacquard fleece with hollow-core yarns traps warmth without holding heat — ideal for fast-paced output in cool conditions
• Zigzag-knit construction increases airflow, accelerates drying, and compresses down to almost nothing in a pack or pocket
• Off-shoulder seams eliminate pack strap pressure points and chafing — wear it all day under a hydration vest without noticing it's there
• Vest cut leaves arms unrestricted for full range of motion on climbs, ski transitions, or technical trail approaches
• Made in a Fair Trade Certified™ factory — your purchase directly supports the workers who made it
