Performance clothing refers to specialized apparel designed to enhance athletic performance and comfort during physical activities. This type of clothing is often made from advanced materials that wick moisture away from the body, provide breathability, and offer flexibility. Common features include lightweight fabrics, ergonomic designs, and added support for specific activities, such as running, cycling, or team sports. These garments are popular among athletes and fitness enthusiasts because they help regulate body temperature and reduce the risk of chafing or discomfort. Brands like Nike, Under Armour, and Adidas are well-known for their performance clothing lines, which cater to various sports and outdoor activities.
