What is Wicking Fabric? Fabric engineered to move moisture from the skin's surface to the outer face of the garment.
Wicking fabrics move sweat away from the skin through capillary action. Polyester, polypropylene, and merino wool all wick effectively. Cotton does not wick — it absorbs and holds moisture. Wicking matters most in active wear, base layers, and any clothing worn next to skin during exercise or cold-weather exposure.
