Leatt helmets feature their category defining 360 degree Turbine Technology and are both ECE and DOT certified. The helmet is lined with turbines, which are 360 degree moving discs constructed from energy absorbing shape and material. The entire outer shell is also reduced in volume, resulting in a significant decrease of rotational acceleration to the head and brain at impact. Carbon matrix shell construction 360 degree Turbine Technology that reduces up to 30% of head impact at concussion level and up to 40% of rotational acceleration to head and brain Reduced outer shell volume which transfers up to 20% less rotational forces to the neck, head, and brain Multi-density, V-shaped impact foam molded directly to the outer shell significantly reduces G-forces transferred to head and brain Dri-Lex moisture wicking, breathable, anti-odor and washable inner liner Emergency cheek pad removal Optimal neck brace compatibility Visor with breakaway function for rotational reduction in crash Maximized ventilation optimized for off-road racing and effective even at very low speeds Hydration ready (with optional hands-free kit, sold separately) DOT and ECE 2205 certified and tested New without original box
