EXCEPTIONAL HEAD & BRAIN PROTECTION   Great safety and comfort.   In our world, crashes are a reality. Give yourself the best possible chance of keeping trauma to a minimum, buy 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.   The 3.5 is both ECE and DOT certified.   New high-performance certification ECE 22.06   Injected Polymer Compound shell in three sizes   Brain injury reduction technology Reduces forces associated with concussion   Large ventilation channels to keep your head cool even at lower speeds   Inner liner is washable, breathable and has moisture wicking anti-odor fabric   Designed to offer great neck brace mobility   Visor has breakaway function to reduce forces to head and neck in a crash   Emergency cheek pad removal   360° Turbine Technology Reduced peak brain acceleration by up to 30% at impact speeds associated with concussion Reduces peak brain rotational acceleration by up to 40%   Certified and tested: DOT + New ECE 22.06   3-year Leatt Helmet Replacement Program.
