What Is MIPS?

In a helmet with MIPS Brain Protection System (BPS) the shell and liner are separated by a low friction layer. When a helmet with a MIPS Brain Protection System is subjected to an angled impact, the low friction layer allows the helmet to slide relative to the head. The MIPS BPS 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 BPS has been proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.

Patented System

A helmet with the MIPS Brain Protection System offers better protection against rotational motion than one without MIPS. Since 1996 research and tests have been performed to compare a helmet with the MIPS Brain Protection System to a conventional helmet. The results showed that it was possible to redirect and reduce the rotational motion transmitted to the brain by adding the MIPS Brain Protection System.

The Great Misconception

Accident statistics show that many injuries occur due to angled impact to the head. However, in standard tests, the helmet is dropped vertically onto a flat surface. The results are helpful for measuring precise vertical impacts, but inferior for measuring the more realistic scenario of an angled impact. MIPS has been developed for reality and increases protection against angled impacts.

The Altitude helmet meets or exceeds DOT & ECE 2205 safety certification standards. It features an innovative dual density, interlocking EPS foam liner that provides top crash protection in the event of an accident. The front chin area of the helmet is protected by a specially designed expanded polyurethane chin insert that provides front impact protection. The outer shell is made of specially designed carbon fiber for maximum shell strength with minimal weight.
