The Delta elbow pad uses a perforated Duratex neoprene with air plush lining for the front section while the back side uses a dual layer Lycra for superior comfort. To protect your elbows from impact we use our DFS foam under a polyamide soft cap. This year we also added Sharkskin neoprene gripper to keep the pad firmly in place. The Delta series pads also features upper and lower straps for a perfect fit.
