Made for aerobic, start-stop days in the mountains — skinning, scrambling, fast approaches and brisk winter runs — the Nano-Air Light Jacket is built to stay on for the entire push. It breathes hard when you're working and holds warmth the moment you stop, so you're never slowed down swapping layers mid-effort.
The whole piece is engineered to move air. A 2-oz, 30-denier 100% recycled polyester air-permeable stretch ripstop shell and a lighter 1.6-oz recycled polyester shadow-ripstop lining sandwich 40-g FullRange® insulation that is warm, stretchy and exceptionally air permeable. Both fabrics carry a durable water repellent (DWR) finish made without intentionally added PFAS, while articulated patterning and low-profile quilting keep everything moving with you.
Standout features:
- FullRange® insulation — 40-g stretchy, air-permeable fill dumps excess heat when you push and traps it when you rest
- Breathable stretch shell — recycled polyester ripstop is abrasion resistant and comfortable next to skin
- Self-stuffing design — the jacket packs into its own left-chest pocket for easy stashing
- Harness- and pack-friendly pockets — two zippered handwarmers plus a zippered chest pocket, all low profile and low bulk
- Center-front zipper — with a zipper garage at the chin for next-to-skin comfort
- Variable Conditions Cuffs — snag-resistant cuffs pull up over the forearms for venting and visibility, with a cleanly finished hem
Materials lean responsible: shell, lining and insulation are all 100% recycled polyester, and the fabrics are certified bluesign® approved with a water-repellent finish made without intentionally added PFAS.
Right pick for high-output cold-weather pursuits — ski touring, winter trail running, alpine climbing and fast hikes — where a static puffy would leave you clammy but a bare shell would leave you cold.
