MIPS (Multi-Directional Impact Protection System) is a specialized helmet safety technology that is now being used in the top tier of off road helmets in order to greatly lessen the chances of traumatic brain injury.
By integrating an engineered low-friction layer into the liner of the helmet, MIPS enables a relative sliding motion between the head and the helmet so angular and rotational impact forces are absorbed and deflected.
Since most head impacts occur at oblique and unpredictable angles, helmets with MIPS Technology are able to offer better protection than helmets without.
Koroyd technology uses a series of hollow, dual-polymer, thermally welded tubes to attenuate and absorb the force of traumatic impacts.
During a crash, the Koroyd tubes compress and effectively create a crumple zone inside the helmet. This technology outperforms EPS in terms of energy absorption, and drastically reduces the occurrence of brain injury compared to other current materials.
The hollow design of Koroyd tubes also dramatically improves air circulation and promotes a lighter-weight helmet overall.
