When freedom of movement is crucial, the men's variant jacket is an adventure-ready option for cold temps-without the bulk. Thermal outerwear insulation is sewn into the front panels for warmth, keeping body heat close to where you'll feel and need it most: your core. Its back and side panels are made up of Polartec Power Stretch fabric that ensures you're able to move on tough climbs or intense trail hikes. Wear it under your favorite base layer, and use the elastic-bound cuffs and hem when you need to keep heat close to your body. If your fingers need additional coverage, slip them into the attached thumbholes to protect them from abrasions and the cold. Use this light jacket's internal and zippered hand pocket for small gear like your keys, phone, cash, and more.
