Features
MIPS (MULTI-IMPACT PROTECTION SYSTEM)
MIPS is a system used to reduce the rotational forces on the brain in the case of oblique impacts. This is achieved by allowing a controlled rotation of the shell relative to the liner.
AEROCORE
Construction through the use of Koroyd® and EPS allows for more vents to be placed throughout the helmet without sacrificing protection and comfort.
KOROYD®
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.
AIREVAC
AirEvac uses a system of shell vents to actively pull warm, moist air out of the user’s goggles and exhaust it out of the helmet to prevent fogging.
