The Fly Racing Kinetic Helmet delivers excellent performance and protection thanks to the poly-alloy shell construction which helps create a durable yet lightweight helmet. The dual density EPS liner is comprised of two layers of EPS (Expanded Polystyrene), one softer and one slightly harder, which combine to provide more progressive impact absorption for different levels of impact. Designed to keep you cool, the Kinetic Helmet utilizes the True Function Ventilation system which promotes maximum airflow.
