G-Form makes use of their RPT technology, which is short for "Reactive Protection Technology". The "Shell" is thinner, lighter and more protective than hard shell shin pads. The RPT technology is revolutionizing due to its soft and flexible shell, but as soon as the shin takes a hit, it hardens. The flexible shell absorbs up to 90% of the energy from the hit, as it gets distributed all across the shin. hereby, the energy is also distributed, and you will hardly feel the impact. RPT Impact Protection is anatomically designed, so the material bends with the body, which means you keep your natural movability and mobility.
