Running apparel plays a crucial role in comfort, performance, and injury prevention. Lightweight, moisture-wicking fabrics help regulate body temperature by keeping sweat away, reducing chafing and discomfort. Proper running gear includes breathable shirts, shorts or leggings, and weather-appropriate layers like windbreakers or thermal tops for colder conditions. Choosing the right apparel ensures a more enjoyable and efficient run, helping runners stay comfortable and focused on their performance.
