Moisture-wicking refers to the ability of certain fabrics to draw moisture away from the skin and transfer it to the outer surface of the material. This process helps keep the wearer dry and comfortable, especially during physical activities like running or exercising. Common moisture-wicking materials include synthetic fibers such as polyester and nylon, which are often used in athletic wear. These fabrics are designed to evaporate sweat quickly, reducing the feeling of dampness. Moisture-wicking technology is popular in sports apparel, activewear, and outdoor clothing, making it a preferred choice for athletes and anyone engaging in vigorous activities.
