Rotational motion affects the brain and increase the risk for minor and severe brain injuries. When implemented in a helmet, the MIPS®BPS can reduce rotational motion by redirecting energies and forces otherwise transferred to the brain.The core of the MIPS®BPS is a low friction layer that allows the head to move 10-15 mm relative the helmet in all directions, reducing rotational motion to the brain. The MIPS®BPS makes your helmet safer and adds protection.
