ENGINEERED ABSORPTION:

The combination of Koroyd's precise and unique thermal welding process leads to a structure with both extremely efficient and consistent energy absorption properties. Upon impact, the cores crush in a completely controlled manner, decelerating the energy from the impact and reducing the final trauma levels.

ENGINEERED PROTECTION:

Thousands of co-polymer extruded tubes, thermally welded to create an unparalleled consistent and fully engineered core. Each Koroyd section is engineered to precise durometer, size, and thickness specifications to provide the greatest impact resistance and aesthetically consistent presentation.

FULL BREATHABILITY:

Koroyd is an energy absorber which is fully breathable and doesn't compromise impact performance. Koroyd's open cell construction allows cool air in while expelling hot air from the rider's head. The completely open cell construction integrates with internal channels to create the full Aerocore construction to provide ventilated protection.

PROTECTION:

Complete Koroyd coverage for lightweight, energy-absorbing, and ventilated impact protection/MIPS Protection System reduces rotational forces caused by angled impacts to the head.
