Leave the protection up to us, so you can confidently enjoy your ride. 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. Confidently work up a sweat knowing the lightweight and breathable Tonic KinetiCore will keep you cool, with twenty-eight vents to improve airflow when you're pushing your pace. Winter kit compatibility offers additional warmth on even the coldest rides of the year, keeping you going strong in every season. Designated eyewear docking slots keep your glasses securely tucked away when not in use, and the helmet's LED light compatible design offers increased visibility and added peace of mind in any light or weather condition. A quick spin of the Advanced TurnSys dial system.
