Whether you're topping out on the Fang or running dawn patrol on Dragon's Tail Couloir staying warm without overheating is critical. The Nano-Air® Light Hybrid Vest traps heat at your core — where you need it most — but lets off steam to keep you dry and comfortable. The front of the vest warms and protects with warm-when-wet FullRange® insulation (40 g) sandwiched between a plain-weave liner and a lightweight yet durable weather-shedding 100% nylon ripstop shell with a DWR (durable water repellent) finish. The back of the vest features a superstretchy airy waffle knit swiftly wicks moisture controls odor and dissipates heat. The center-front zipper has a zipper garage for comfort on the chin and zippered handwarmer pockets rest easily under a harness or pack. Stretch binding at the armholes and hem seal in warmth.


  • Light yet durable 100% nylon ripstop shell and plain-weave liner offer generous mechanical stretch and exceptional breathability with a DWR (durable water repellent) finish
  • Revolutionary 40 g FullRange® insulation warms and stretches; combined with the shell and liner this creates a vest with excellent mechanical stretch and unprecedented air permeability (40 CFM on front; 130 CFM knit on back)
  • Airy wicking waffle knit on the side-and-back panel manages excess heat and moisture
  • Minimal center-front zipper with low-profile zipper garage
  • Two handwarmer pockets are zippered welted and low-bulk to wear comfortably with a harness or pack
  • Stretch binding at armholes and hem to seal in warmth
  • Shell: 1.3 oz. 20 denier 100% nylon ripstop
  • Lining: 2 oz. 50 denier 100% nylon plain weave
  • Both shell and lining with mechanical stretch and a DWR (durable water repellent) finish
  • Insulation: 40 g FullRange® 100% polyester stretch insulation
  • Knit: 6.3 oz. 100% polyester stretch waffle knit with Polygiene® permanent odor control
