Koroyd is a new energy absorbing technology, engineered with a unique structure which reduces trauma levels with innovative energy management properties. When impacted the Koroyd cores crush homogeneously, decelerating the energy from the impact and reducing trauma levels. 

The F5 Koroyd also features MIPS, a low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts.
