Running apparel refers to specialized clothing designed for runners to enhance comfort and performance during their workouts. This includes items like moisture-wicking shirts, breathable shorts, and lightweight jackets that help regulate body temperature and keep sweat away from the skin. Additionally, running apparel often features reflective materials for safety during low-light conditions and pockets for storing essentials like keys or energy gels. Many brands also offer compression gear to support muscles and improve circulation, making it easier for runners to maintain their endurance over longer distances.
