Ultimate head and brain protection. The best safety and ProFit comfort. 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. This technology has two key advantages, the reduction of rotational acceleration to the head and brain and the absorption of energy upon impact at concussion level. Once on your head you will quickly forget you are wearing a helmet. The Pro-Fit modulating comfort liner stretches over your head to provide superior comfort and stability.
