The best safety & 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 & 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 & deflective impact energy. This technology has two key advantages, the reduction of rotational acceleration to the head & brain & the absorption of energy upon impact at concussion level. The 3.5 is both ECE & DOT certified. Features Injected polymer compound shell in 3 sizes 360° Turbine Technology: reduces impact forces by up to 30%, reduces rotational forces by up to 40%. Impact foam with different viscosities reduces G-forces acting on the head & brain. Dri-Lex antibacterial, removable, moisture wicking lining. Perfectly matched to the Neckbrace Very good ventilation Helmet shield with predetermined breaking points in the screws for greater safety Removable cheek pads Double-D chin strap Tested according to: DOT + ECE 22.05 Weight from 1.150 gr. +/- 50 gr.
