The slim-fit Men’s North Face Summit Series FUTUREFLEECE™ Full-Zip Hoodie features an innovative technology that uses a full-loop fabric to minimize weight and help optimize body temperature. It’s designed to be worn over a base layer or under whatever insulation the mission calls for. Flat-locked stitching and no shoulder seams help maintain your comfort when wearing a pack, while a pre-tensioned hood can easily be worn under a helmet.
