For athletes facing biting winds, the Womens Windwall" 1 Jacket helps you fight back with a wind-resistant fleecy layer. It uses WindWall", the proprietary fleece from The North Face® that uses a fabric bonding process to limit air permeability and reduce the wind chill. Wind permeability rated at 14 CFM, its powerful enough to insulate in moderate cold weather, keeping you going on your run or hike while others feel the icy blasts. Alternatively, pair it with other layers from The North Face® for superior protection from the wintriest of conditions. A mesh lining leaves it comfy to wear too, and side hand pockets, a full-length zip and swish design complete the look.
