Patagonia Nano-Air® Hoody was made to be worn for the entirety of your aerobic, start-stop alpine missions, so you’re never slowed down by changing layers. Warm, stretchy and breathable FullRange™ insulation dumps excess heat when you’re working hard and keeps you warm when you’re not. Now built with significant recycled content in the shell, liner and insulation, the Nano-Air sets another new standard for technical insulation. Fair Trade Certified™ sewn. Slim Fit: Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.   Patagonia Men’s Nano-Air Hoody 84366
