Met Helmet Roam MIPS - Black/Red - MTB Helmet

The Mips® safety system features a low-friction layer inside the helmet that allows a multi-directional movement of 10-15mm on certain angled impacts, intended to help reduce rotational force to the head. 

What is rotational motion?

Rotational motion, in these cases, can be the result of an angled impact to the head. These impacts may result in an abrupt stop that can cause the brain to move or stretch.

Why is rotational motion harmful?

The brain is more sensitive to rotational motion than linear motion because it has shear properties similar to water or gel. When different parts of the brain move relative to each other as a result of rotational motion, the tissues can stretch, which can cause concussions or other brain injuries.

Where is the MIPS safety system located on a helmet?

Mips is found inside the helmet, generally between the padding and the EPS foam protective layer. There are different Mips systems, but all consist of a low-friction layer between the helmet and the head.
