Mips Evolve Core Mips Evolve Core is designed to add protection in helmets against the rotational motion. The rotational motion is a combination of rotational energy angular velocity and rotational forces from angular acceleration that both affects the brain and increases the risk for minor and severe brain injuries. Mips has been scientifically proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.
