Moisture-wicking refers to the ability of certain fabrics to draw sweat and moisture away from the skin. This process helps keep the body dry and comfortable during physical activities. Materials like polyester and nylon are commonly used in moisture-wicking clothing, as they have special properties that allow them to absorb moisture and then evaporate it quickly. This technology is particularly beneficial for athletes and outdoor enthusiasts, as it helps regulate body temperature and reduce the risk of chafing. Many brands, such as Under Armour and Nike, incorporate moisture-wicking fabrics into their sportswear to enhance performance and comfort.
