Wicking: What It Is and Why It Matters Outdoors
Wicking (or moisture-wicking) is a fabric's ability to draw sweat away from the skin and spread it across the fabric's surface, where it evaporates more quickly. By moving moisture off your body, wicking fabrics keep your skin drier — which keeps you warmer in the cold and cooler when working hard. It is the defining property of a good base layer and the reason to avoid cotton outdoors.
