For 2018 We are proud to announce the addition of MIPS™ to our new JDH Helmets
MIPS™ stands for Multi-directional Impact Protection System, which is a leading slip-pane technology inside the helmet designed to reduce rotational forces that can result from certain impacts
Why It's important
When a head rotates quickly and comes to a sudden stop, the rotational acceleration can cause the brain tissue to experience high levels of strain. The stretching of the tissue that can be caused by these motions can result in various types of brain injury. We belive that helmets equipped with MIPS™ technology can provide an additional measure of protection in certain imapcts.
How it works
MIPS™ uses a slip-plane system that moves inside the helmet, mimicking the brain's own protection system. This layer is designed to rotate inside the helmet with the intent to potentially slow or reduce the amount of energy transferred to or from the head. Science tells us that if we can reduce the strains associated with rotational acceleration, we might reduce the risk and severity of brain injury.
