These single-use balaclavas (head socks) are a great way to keep loaner helmets fresh and clean. The soft, felt-like material is comfortable to wear, but protects the helmet lining from dirt, perspiration, and odors. Excellent addition to any supply of loaner helmets -- go-kart vendors, Solo programs, or ride-alongs. Pack of 25 white balaclavas, one size. Not flame retardant.
