Product details:

For elite-level protection on rugged trails and fast tracks, the G-Form Elite Knee Guards are breathable, lightweight and perfect for all day riding or race day performance. They CE 1621 Level 1 certified, the highest standard for joint protection. The molecules in the foam slightly repel each other making it soft and flexible, then upon impact the molecules bind together causing the pad to stiffen, absorb and redistribute energy from the impact. Once the energy from the impact dissipates, the molecules return to their original state.
