Nano-Air Light Vest – Men's

For cool starts that turn warm by mid-morning, the Nano-Air Light Vest is our go-to insulating layer for hikers, hunters, and trail runners who run hot. FullRange insulation holds warmth at rest and vents heat when you pick up the pace, while the stretch face keeps your arms moving freely.

• FullRange insulation traps warmth when you're standing still and breathes when your effort climbs, so you don't sweat through it on the ascent
• Stretchy recycled polyester face fabric moves with you on scrambles, steep climbs, and a full bow draw
• Low-bulk build slides under a shell or over a base layer without binding or bunching
• Sleeveless cut warms your core and leaves your arms cool, which suits shoulder-season mornings in the Southeast
• Packs down small enough to stash in your pack once the morning chill burns off
