Running shorts are lightweight, breathable garments designed specifically for running and other athletic activities. They typically feature a loose fit to allow for freedom of movement and are made from moisture-wicking materials that help keep the wearer dry. Many styles include built-in liners for added comfort and support. These shorts come in various lengths, from mid-thigh to knee-length, catering to different preferences and weather conditions. Some running shorts also have pockets for storing small items like keys or energy gels. Popular brands include Nike, Adidas, and Under Armour, each offering a range of styles and colors.
