ADVANCED BREATHABILITY & COOLING
HOW DOES KOROYD PERFORM IN HEAT?
Air flows consistently through the open-cells, whilst hot air from your head can
easily escape, ensuring more efficient cooling in the most intense conditions.
MAXIMUM VENTILATION
For helmets featuring Koroyd, the consistent tubular structure allows for maximum ventilation across the entire surface of the core – without compromising on safety.

FOAM DOESN'T BREATHE WELL
Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam made of pre-expanded polystyrene beads. This foam is traditionally used to package food and for building insulation.
To build EPS foam only helmets with more ventilation, helmet designers must remove some of the energy-absorbing material. This means that adding ventilation ultimately compromises on helmet performance and safety.
Also, the performance of EPS foam is much more variable in comparison to Koroyd because it stiffens when cold and softens when hot. Koroyd’s performance is consistent in temperatures of -20°C to +50°C.
