Radians Arctic Radwear® Headbands are made with Advanced ARCTIC™ Technology that accelerates the evaporative cooling process. Just soak the band in water for 2-3 minutes and then wear it for up to 5 hours of cooling relief. Our patent pending stretch-fit spandex design allows the band to move with your body, not against it, allowing for optimum blood circulation, keeping you cooler and providing a noticeably more comfortable fit than standard headbands. The Arctic Radwear® Headband is designed to keep you cool during hot outdoor activities, such as construction work, tough workouts, or any strenuous outdoor or indoor activity. In fashionable blue paisley, this headband is an excellent solution for comfortable heat protection!
