Give your players a snug, comfortable helmet fit on the gridiron with the Riddell Helmet Pump Kit. Complete with a helmet pump, a 5/8' inflation needle and a 1 oz. bottle of glycerine, the Riddell Helmet Pump Kit helps you easily inflate and deflate the pad liner system of any Riddell football helmet to give players a secure, non-slip fit. The glycerine lubricant helps eliminate the chance of puncturing the liner.
