Not your average half-zip pullover, the Mountain Hardwear Stretchdown Light Pullover Hoodie holds in serious heat when we're climbing, camping, hiking, or backpacking in the cold. Luxuriously light and lofty, the Stretchdown sweater strings together baffles of insulating down to keep us warm while maintaining our freedom of motion with the single-stretch fabric shell. This pullover also packs down into its right-hand stow pocket, so it fits easily in our pack or luggage until we pull it out to layer over our baselayer or under our waterproof shell.
