The average person can produce two to three quarts of sweat an hour. While sweat evaporation produces a natural cooling effect, all sweat does not evaporate and can add up to gallons of drippy, distracting, annoying sweat each day. Plush, super absorbent 100% cotton terry sweatband, with easy snap-on application helps headgear fit more securely. Reusable, machine washable and one size fits all. Sold by the each.
