The Women's Nano-Air® Light Vest was made for start-stop mountain days when you never want to stop to change layers. Built for aerobic, high-output efforts, it dumps excess heat when you're working hard and holds warmth the moment you slow down — so your core stays regulated from the first climb to the last descent.
The magic is in 40-g FullRange® 100% recycled polyester insulation, which is warm, stretchy and exceptionally air permeable. It pairs with a 2-oz 30-denier 100% recycled polyester air-permeable stretch ripstop shell and a 1.6-oz recycled polyester shadow-ripstop lining, both treated with a DWR finish made without intentionally added PFAS. Low-profile quilting and a regular fit keep layering easy and movement unhindered.
Standout features:
- FullRange® insulation — stretchy, air-permeable synthetic fill that breathes hard so you don't overheat mid-effort
- Freedom of movement — vest pattern gives total range of motion around arms and shoulders
- Center-front zipper — finished with a zipper garage at the chin for next-to-skin comfort
- Three zippered pockets — two handwarmer pockets plus a left-chest pocket, all low-profile under a pack or harness
- Self-stuffing — the vest packs down into its own chest pocket
- Low-bulk finish — cleanly finished armholes and hem keep things trim
Sustainability is built in: the shell, lining and insulation are all 100% recycled polyester, the fabrics are certified bluesign® approved, and the water-repellent finish is made without intentionally added PFAS.
The right pick for trail runs, ski tours, alpine climbs and cool-weather hikes — any variable-intensity day where you need warmth over the core without sacrificing breathability or freedom to move.
