For the big-time task of stopping wind and icy air, nothing beats a warm balaclava. Ours is made from Capilene® Thermal Weight, the warmest and most breathable baselayer in the Capilene® family. It is soft, stretchy and compressible, with a smooth jersey face that glides beneath layers and a brushed-fleece interior to insulate, wick moisture and rest smoothly against the skin. The face opening fits above your mouth or under your chin, depending upon the coverage you require. Made of 3.8-oz proprietary performance Polartec® Power Grid™ fabric, with Polygiene® permanent odor control.
