G-Form uses its Reaction Protection Technology™ that allows the pads to stay soft and only harden on impact.INSIDE THE PADThe molecules in the foam slightly repel each other, making the material soft and flexible.UPON IMPACTMolecules bind together causing the pads to stiffen, absorb, and redistribute the energy from the impact.AFTER IMPACTOnce the energy from the impact dissipates, the molecules return to their original state and the pads go back to being soft and malleable.
