Hurtle down the hills with an easy mind in the Demon Hyper X D30 V2 Knee Pads. A ballistic fabric front shield protects against sharp edges, side padding preserves the peripheries, and the low-profile, form-fitting design allows you to ride freely. The enclosed D3O padding is a flexible material that hardens on impact, allowing excellent freedom of movement and flexible protection. Reinforced stitching on the seams and face fabric increases overall durability, and the perforated neoprene and lycra back fabric vents moisture to keep you from getting swamped with sweat.
