The best safety and Pro-Fit comfort. Leatt helmets feature category-defining 360 ̊ Turbine Technology, the helmet is lined with 360 ̊ turbines, which are discs constructed from an energy-absorbing material designed to allow the head to move slightly inside the helmet during a crash reducing rotational, direct, and deflective impact energy. Once on your head the 8.5 will make you forget you are wearing a helmet at all, due to the lightweight Composite shell and Pro-Fit modulating comfort liner that stretches over your head like it was made just for you, providing superior comfort and stability. The 8.5 is a great choice for any Thrill-seeker and is both ECE and DOT certified! Includes visor extender, helmet bag and FREE Leatt Velocity goggles!
