Built for aerobic, start-stop days in the mountains, the Men's Nano-Air® Light Vest keeps your core warm without ever asking you to stop and change layers. Stretchy, breathable FullRange® insulation dumps excess heat when you're working hard and holds warmth when you slow down—so you can climb, skin and move at pace with one piece on your back.
The shell and lining are 100% recycled polyester ripstop with mechanical stretch, exceptional breathability and improved abrasion resistance, finished with a DWR (durable water repellent) made without intentionally added PFAS. Inside, 40-g FullRange® insulation delivers outstanding stretch and air permeability (35 CFM), while articulated patterning and low-profile quilting give an exceptional range of motion for unhindered movement.
Standout features:
- FullRange® active insulation — breathes and stretches so excess heat moves away from the body
- Recycled ripstop shell — air-permeable stretch shadow ripstop resists light moisture and abrasion
- Three zippered pockets — two handwarmer pockets plus a left-chest pocket, low profile and low bulk
- Self-stuffing — the vest packs into its own chest pocket
- Harness- and pack-friendly — slim pockets sit comfortably under a hipbelt or climbing harness
- Microtexture face — keeps the fabric from sticking to skin for versatile comfort
Made in a Fair Trade Certified™ factory, which means the people who made this vest earned a premium for their labor.
The right pick for high-output pursuits where a jacket would be too much—ski touring, alpine climbing, trail running in the cold and shoulder-season hikes where you want core warmth without overheating or bulk.
