The Safe-Quip U-Shaped Helmet Support is made of high-density flame retardant foam which is covered with a woven FRC fabric. The 2" tapered wedge design plus the Velcro? closure make our helmet supports comfortable and easy to use. Available in black, red, and blue. Remember! The solid side of any U Shaped Helmet Support is to be worn in the front so that your chin does not bounce against your chest in an impact. The Velcro ? closure should be attached behind your head.
