MIPS (Multi-Directional Impact Protection System) is a sliding plane system designed to rotate within the helmet with the intent of reducing and slowing the amountof energy transferred to the head and intended to decrease injuries caused by rotational impacts.
MIPS required several years of collaboration with the designers. The technology was developed by scientists at Karolinska Hospital and the Royal Institute of Technology in Stockholm, Sweden. The concept is founded on 19 years of academic research.


When a head rotates quickly and stops suddenly, rotational acceleration can cause brain tissue to experience high levels of tension. The stretching of the tissue caused by these movements can lead to various types of brain injuries. MIPS was designed with the intent to address the rotational acceleration generated by impact.


A helmet equipped with MIPS technology consists of three main components: the shell in expanded polystyrene (EPS), the low-friction shell and, between the two, a fastening system using elastomers. In an angled impact, the elastomer fastening system tightens to allow the EPS shell to rotate independently around the head. How far does the system move? Just by a couple of millimetres. But the few millimeters of shift during those crucial 2 milliseconds can reduce the amount of rotational force that can be transferred to the brain.

MIPS, in essence, uses a sliding plane system that moves inside the helmet, precisely imitating the protection system of the brain.This layer is designed to rotate within the helmet with the intent to slow or reduce the amount of energy transferred to or from the skull and thereby reduce the risk and severity of brain injury.
