form a single unit.MIPS (Multi-Directional Impact Protection System) The MIPS fall protection system is a low-friction layer under the helmet padding that reduces the rotational forces transmitted to the brain during an impact. This layer allows the head to move 10-15mm relative to the helmet in all directions during a fall, redirecting energies and forces that would otherwise be transmitted to the brain. MIPS helmets are designed to protect the brain from an angled impact because angled falls create rotational forces that are transmitted to the brain and can lead to brain injury. MIPS can reduce both rotational movement and the risk of brain damage.
