Halo II Headband Sweatband - 2 Pack Black Pullover Headbands for Running, Workout & Sports - Moisture Wicking & Non-Slip Design

I wear these while bicycling. I sweat a lot and I've found these are the best headbands for preventing sweat dripping into my eyes. They are thin enough that they fit comfortably beneath my hellmet. I have an extra large head, so they are little tight the 1st few times I wear them; then they stretch enough. I've worn them for years. The yellow plastic strip will come off after a year or two of use, but the headband works about as well without it. Otherwise, they last for several years. I guess I lose them before they wear out. They don't help much to keep your head warm in the winter, don't buy them for that purpose.
