Unlike other sweatbands, on the inside of the Halo Headband there is a yellow Sweatblock seal which sits against the forehead, just above the brow line, and redirects sweat to the sides of the head, away from the eyes and face, even if the sweatband becomes saturated. The result is the face stays dry, no stinging eyes caused by dripping sweat so you can concentrate on working out, training or competing.
