When cool temps hit, this midlayer is the ultimate all-season companion from high-effort, high-reward pursuits to casual objectives around town. The key to its blend of performance and warmth is Polartec® Power Stretch™?. Designed with a dual-surface construction, its fleecy interior absorbs moisture from the skin and wicks it to the outer layer for fast evaporation, while premium elastic fibers provide shape-retaining 4-way stretch. Layered over a baselayer or under a shell, other thoughtful features include a fixed hood with an elastic opening, full front zip and zippered hand warmer pockets.
