X-BIONIC Headband High
X-BIONIC® HEADBAND. No matter what sport you do, the body temperature rises quickly over the optimal temperature of 37 °C. We start to sweat ? especially around the head, because there the body can release the most heat. But before the sweat starts to trickle down the face, it is absorbed by the 3D Bionic Sphere® System on the forehead and used effectively for cooling. This way athletes can maintain their best performances.
