The Nano-Air® 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. This jacket is lightly worn. Only flaw is some pilling on the cuffs -see pictures. Otherwise this jacket is in excellent condition and there or no rips, pulls, or stains.
