Product details

This Enduro MTB helmet, known for its excellent ventilation and comfort, is the evolution of the popular 4.0 full-face helmet.

Equipped with unique features, this helmet stands out from the crowd. A removable mouthpiece in the chin bar ensures better ventilation and provides protection in bad weather. The universal sunglasses dock allows for secure storage of your glasses under the visor, protected from scratches and impacts. The adjustable visor opens wide enough to place your glasses underneath.

This fully ASTM DH-certified helmet is ideal for enduro riders. Whether climbing or descending, on an e-bike or trail – the Leatt 4.0 Enduro helmet consistently delivers top performance. The full-face design with a removable chin bar and strong magnesium lock ensures optimal 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.

The helmet features a DH-certified lightweight polymer shell, a removable chin bar with an Easy-Fit attachment system, a sunglasses docking port, the Fidlock magnetic closure system, and 360° turbine technology. It reduces peak brain acceleration by up to 30% at impact-related speeds and the maximum rotational acceleration of the brain by up to 40%.

With 18 ventilation openings, the helmet offers maximum airflow, even at low speeds. The inner lining is moisture-wicking, breathable, odor-resistant, and washable. The helmet is compatible with neck braces, and the adjustable visor has a breakaway function to reduce rotational impact force. Molded EPS + EPO impact foam provides excellent safety.
