Omni-Wick® is a moisture-management technology that works perfectly as a baselayer. Lightweight and quick drying, it works to transfer moisture away from your skin to the outer layers of the fabric where the moisture can easily evaporate, leaving you cool and dry. Aside from its baselayer application, Columbia also uses Omni-Wick® in some of it’s technical shells and other active outerwear pieces, where wicking and weather protection are both key.
