Generation 3 now better than ever! Military Grade knee protection in a streamlined package!
The S-ONE Pro Knee Pad is thoughtfully designed with comfort, durability and function in mind. After three years in development and thousands of hours of wear testing, S1 presents a high-performance knee pad that's tough enough for top level derby! Generation 3 now incorporates one significant manufacturing change: The inner layer of Ortholite High Rebound Memory foam is now expanded to cover lower on the leg and higher up on the knee. The S-ONE Pro knee pad comes with a replaceable, durable black or white polycarbonate knee cap. See instructions for sizing below.
