Arctic Skull Cooling Head shade made with Advanced Arctic Technology that accelerates the evaporative cooling process to combat heat stress. Just soak the head shade in water for 2-3 minutes and then experience cooling relief for up to 5 hours. Our patented spandex design allows the head shade to move with your body, not against it, allowing for optimum circulation, keeping you cooler and providing a noticeably more comfortable fit than standard headbands. The Arctic Skull(TM) Head shades are designed to keep you cool during hot outdoor activities, such as construction work, touch workouts, or any strenuous activity.
