When a helmet with the Mips Brain Protection System is subjected to an angled impact, the low friction layer inside the helmet (identified in this image in yellow) allows the helmet to move. That movement during those crucial first .0002 seconds can reduce the amount of rotational motion (a combination of rotational energy and rotational forces) transferred to the brain and reduce the risk for minor and severe brain injuries. It’s important to acknowledge that no helmet, including Mips-equipped helmets, can prevent all potential injuries. But by reducing energy transmitted to the brain, the potential for and the severity of a brain injury can be reduced and you likely won’t even notice Mips, but your brain will when it needs it the most.
