The Pro Derby Knee Pad brings years of roller derby experience to your knee, featuring a design specifically tailored for roller derby with a low profile and less bulk while providing a high level of protection. It incorporates the 187 Killer Pads® Lock-In™ Core System, which includes removable foam for easy washing and interlocking straps that link the foam to the center of the pad casing. The V-22™ Dual Density Foam is specially formulated to offer an optimal combination of cushion and protection against multiple hard impacts. A Rapid F L E X™ Hinge allows the pad to respond freely to a full range of motion, enabling the leg to straighten or bend with minimal resistance. Additionally, the Fusion Groove™ Channel helps maintain foam connection to the skater's leg, eliminating pad slip-downs. The pads are constructed with ballistic nylon and industrial-weight stitching for enhanced durability, along with a light-weight, fast-drying interior lining and a seamless interior finish for ultimate comfort.
