The Thin Headband On/Off is an elegant, slim running headband that offers optimal ventilation. Thinner than the classic model, the black headband provides a sleek, modern look. Its stretchy, seamless material is designed for ultra-effective temperature regulation and high comfort during training and competition. The On/Off technology ensures all-around ventilation and quickly wicks away sweat. The material is water-repellent and dries up to seven times faster than traditional headbands, ensuring that your head stays cool even in hot conditions. The ultra-soft, stretchy fibers conform to the contours of your head and ears without creating uncomfortable pressure points. Eyes and forehead remain free from sweat and unruly hair. The band can also be worn under a hood or helmet without the risk of chafing or irritation.
