Lightweight, low-profile and infinitely comfortable in a range of conditions, Polartec® Power Grid™ fleece is the secret to this midlayer’s powerful warmth and minimal bulk. The interior’s raised grid design increases breathability and keeps volume down, holding in heat when it's needed and letting it out when it's not. It quickly wicks moisture from skin, keeping you dry and comfortable. The streamlined hood adds more options for warmth, with elastic that prevents it from slipping while on the move. Flatlock seams ensure smooth layering while thumbholes keep sleeves in place. A concealed zipper pocket on the lower hem stashes small essentials.
