VaporWick® is a proprietary fabric of The North Face® that moves moisture and sweat away from the skin to the outer surface of the fabric where it can readily evaporate.
This process is accomplished by the capillary action of hydrophobic fibers. Capillary action moves moisture and sweat in all directions from where it is abundant (the user's skin) and transports it to areas of lesser density (the fabric's outer surface). The removal and evaporation of sweat and excess moisture helps to keep you dry and comfortable.
