MIPS (Multi-Directional Impact Protection System) is an additional brain protection system.
MIPS is designed to add protection against rotational motion (or kinematics) transmitted to the brain from angled impacts to the head, which is how most riders fall.
Rotational motion is a combination of rotational energy (angular velocity) and rotational forces from angular acceleration that both affect the brain and increase the risk for minor and severe brain injuries.
MIPS’ added protection system has been proven to reduce rotational motion when implemented in a helmet by redirecting energies and forces otherwise transmitted to the brain.
