Designed for cold-weather hiking, this top features breathable grid-back fleece that wicks moisture and retains body heat. Contouring checkerboard-patterned fleece provides lightweight warmth, with raised sections that trap heat and lower channels that wick sweat away from the skin. The lightweight, packable design incorporates Nike Therma-FIT technology to manage natural body heat. Flat seams and stitched panels through the shoulders and underarms follow the body's shape to allow for unrestricted movement. A half-zip design allows for adjustable coverage, while elastic hem and cuffs secure the fit and retain warmth. thumbholes vertical zippered chest pocket embroidered ACG logo at left chest blend standard fit
