In our world, crashes are a reality. Give yourself the best possible chance of keeping trauma to a minimum by selecting the best helmet you can find to protect your head and brain. 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. The 3.5 is both ECE and DOT certified.
