When you need to move fast and light in the backcountry while also remaining incredibly warm, this technical mid-layer will make all the difference. Like the fur of a bear, but with an exceptional warmth-to-weight ratio, Polartec Thermal Pro Grizzly fleece combines textures and pile lengths to trap warm air even closer to the body. With a soft hand, the hybrid construction features a Thermo 3D design to optimize temperature regulation in targeted areas. Stretch FlashDry panels down the sides and under the arms provide breathability and moisture management to keep you dry and warm throughout stages of intense activity in cold temperatures. Additional features include thumbholes at cuff and two secure-zip hand pockets.
