I sweat big time when I exercise. I have tried numerous headbands. All of them get soaking wet in no time and then they are useless. Halo headband is made of a special material that gets wet, wicks away the sweat preventing the sweat from dripping into your eyes. After each use I rinse them thoroughly and hang to dry. They dry in several hours. I wear the headband at the gym, under my bike helmet and under my baseball cap. I also wear the band if I am going to do physical work outside or around the house. I panic if I misplace my headband so I also have a backup.
I just love this headband!
