The Nano-Air® Light Vest was made to be worn for the entirety of your aerobic, start-stop mountain activities, so you’re never slowed down by having to change layers. Stretchy and breathable FullRange® insulation dumps excess heat when you’re working hard and keeps you warm when you’re not. Made in a Fair Trade Certified™ factory.

• Stretchy, Breathable and PFC-Free Fabric
  The 100% recycled polyester ripstop shell and lining fabric offer mechanical stretch, exceptional breathability and improved abrasion resistance, with a PFC-free DWR finish (durable water repellent coating that does not contain perfluorinated chemicals) to resist light moisture; the microtexture keeps fabric from sticking to the skin for versatile comfort

  40-gram FullRange® 100% polyester (93% recycled) insulation delivers outstanding warmth, mechanical stretch and air permeability (35 CFM), allowing excess heat to move away from the body
