Multi-directional Impact Protection System

Multi-directional Impact Protection System, MIPS, is a technology that allows a helmet slide relative to the head, adding more protection against rotational violence to the brain caused by angled impacts. It was developed by biomechanical specialists at the Royal Institute of Technology (KTH), in , Sweden. MIPS is a form of slip plane technology, meaning that a MIPS helmet is constructed from two layers that rotate against each other, mimicking the rotation of the brain’s own cerebrospinal fluid, which is the body’s natural defense against oblique impacts.

The outer layer of a MIPS helmet is made from the same impact-absorbing EPS material as a conventional helmet. It’s connected via an elastomeric attachment system to a low friction inner layer, which is what rests on the rider’s head. In a crash, the outer shell of a MIPS helmet absorbs linear impact, while the inner layer rotates up to 5mm, absorbing rotational impact. This small rotation of the liner relative to the shell results in a significant reduction of the forces on the brain, which reduces the likelihood of concussion and other brain injury.

In 1995 Swedish neurosurgeon Hans Von Holst began evaluating the general construction of helmets. Following several years of study and work related to head trauma for the World Health Organization in Geneva, he determined existing helmet technology provided inadequate protection against brain trauma – with devastating consequences for victims of brain injuries. Together with Royal Institute of Technology researcher, Peter Halldin, Von Holst collaborated on developing a technology that would provide a significantly more effective protection against head trauma. After thoroughly evaluating the brain anatomy, physiology, and combining their years of testing and expertise, Von Holst and Halldin produced and created what is now recognized as the Multi-directional Impact Protection System. A technology that mimicks the brain’s own protective structure.
