The Nano-Air® Vest was made to be worn for the entirety of your aerobic, start-stop alpine missions, so you’re never slowed down by changing layers. Stretch fabrics and insulation, articulated patterning and strategically placed, low-profile quilting provide exceptional range of motion for unhindered movement. Two handwarmer pockets and a left-chest pocket are zippered, low-profile and low-bulk to wear comfortably with a harness or pack. Revolutionary 60-g FullRange® insulation (40% recycled) warms and stretches and, combined with the shell and lining, supplies outstanding mechanical stretch and unprecedented air permeability (40CFM), allowing excess heat to move away from the body. Best of all, it self-stuffs into left-chest pocket for convenient carry.
