This enduro MTB helmet, known for its excellent ventilation and comfort, is the further development of the popular 4.0 full-face helmet. Equipped with unique functions, this helmet stands out from the crowd. A removable mouthpiece in the chin bar provides better ventilation and offers protection in bad weather. The universal sunglasses dock allows you to store your glasses safely under the visor, protected from scratches and knocks. The adjustable visor opens wide enough to fit your goggles underneath. This fully ASTM DH-certified helmet is ideal for enduro riders. Whether uphill or downhill, e-bike or trail - the Leatt 4.0 Enduro helmet always offers maximum performance. The full-face design with removable chin guard and strong magnesium lock ensures optimum ventilation. The practical Fidlock buckle makes it easy to put on and take off. Safety is crucial: Leatt helmets feature 360° turbine technology, which reduces rotational acceleration and impact energy on the head and brain. Push your limits without compromising on safety.
