What is the Mips security system?

The safety system Mips" was developed by a neurosurgeon and a biomechanical scientist and revolutionized the world of helmet safety.
The Mips system is designed to provide more safety to helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotary motion that could otherwise move to the head.

How does the Mips system work?

Should you have an accident and hit your head, your helmet’s Mips system is designed to help reduce the rotational motion of some impacts that might otherwise be transferred to your head. Rotational motion is a common cause of concussions and more severe brain injury in the case of oblique blows to the head. The Mips system consists of a low friction layer mounted inside the helmet. In the event of an accident, the low friction layer is designed to move slightly inside the helmet to help redirect forces away from the head. This is intended to help reduce the risk of brain injury.

Over the years, the security systems of the Mips² have become a key feature in the helmets of the world’s leading manufacturers. . From cycling and snow sports to motor sports, team sports and even construction, Mips has. high safety standards in a wide range of industries and activities.
Always make sure you use a helmet that is suitable for you and certified for your sport or activity.
