To protect your knees from impact we use our DFS system foam under a polyamide soft cap, with additional padding for side impacts. The shin section uses a hard plastic shield with a soft dual layer foam backing. The ankle protector also uses a breathable perforated & tougher Duratex neoprene with air plush lining for maximum comfort. To protect your ankles from impact we use EVA foam padding & polyamide hard shields. This year we also added Sharkskin neoprene on the inside of the pad, acting as a gripper to keep the pad from slipping. The Echo 125 pads also feature redesigned adjustable straps for a perfect fit
