The Echo 125 pads use a perforated neoprene with a durable Cordura & Duratex outer layer & comfortable air plush inner lining. To protect your knees from impact we use SAS-TEC, soft & flexible Visoelastic foam for superior comfort but also extreme impact absorption. The shin section uses a hard plastic shield with a soft dual layer foam backing. This year we also added Sharkskin neoprene on the inside of the pad, acting as a gripper to keep the pad from slipping when wet. To protect your ankles from impact we use EVA foam padding & polyamide hard shields. The ankle section is is adjustable thanks to it’s velcro tabs, or can be fully removed if desired. The Echo 125 pads also feature redesigned adjustable straps for a perfect fit.
