The new Roller Derby 3.0 Knee Pads features sewn PE caps and our unique Double Velcro closure straps. This sewing-on cap complies with new US rules designed to minimize damage to arenas. The Double Velcro closure on the top strap guarantees a secure fit and hold while eliminating snagging on players' clothing. A customisable bottom strap with concealed, quick-release buckle and open back butterfly neoprene straps then deliver perfect fit and size management. Add to this a slim-line ergonomic profile for obstruction free racing, “printed” silicone circles on the inside of the pad to prevent slipping and surround multi-layer EVA foam protection on the knee and you have the ultimate track kneepad.
