With its one size fits all design and precise adjustability of the TurnSys system, a secure and comfortable fit is guaranteed. Winter Kit compatibility keeps you pedaling all year round, offering increased warmth during those brisk rides with a simple swap of the original KinetiCore padding for a cozy fleece conversion that blocks cold breezes and keeps your ears warm. Focus on the ride ahead and leave the protection up to us. KinetiCore by Lazer is the world’s first responsibly designed and fully Integrated Rotational Impact Protection technology that’s built better by design, integrated right into the helmet instead of added on after, it delivers next-level protection while reducing weight and increasing ventilation. This helmet scores a “Very Good” 4-Star protection rating from Virginia Tech.
