The Echo 75 pads use a perforated neoprene with a durable Cordura and Duratex outer layer and comfortable air plush inner lining. To protect your knees from impact Fuse use SAS-TEC, soft and 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 they also added Sharkskin neoprene on the inside of the pad, acting as a gripper to keep the pad from slipping when wet. The Echo pads also feature redesigned adjustable straps for a perfect fit.
