DH CERTIFIED REMOVABLE CHIN BAR HELMET WITH HEAD AND BRAIN PROTECTION

Renowned for its ventilation and comfort, this enduro MTB helmet has been advanced from the much loved 4.0 full face helmet.

The heart of the the Enduro 4.0 is the structurally sound, and easy to operate, removable chin bar design, but the adaptability goes much deeper. A removable mouthpiece in the chin bar increases ventilation or can be installed to protect you when riding in poor weather conditions. A universal sunglasses dock lets you safely dock your sunglasses under the visor when not in use, protected from scratches and unwanted impacts. And the adjustable visor extends enough to place your goggles underneath, so you don’t have to constantly remove them.

This fully ASTM DH certified helmet is the go-to helmet for enduro riders. Uphill or downhill, E-bike or trail - you name it, the Leatt 4.0 Enduro helmet has you covered. The full-face design with removable chin bar with an incredible strong magnesium lock offers outstanding ventilation and its convenient Fidlock® buckle is easy to operate even when your fingers are cramping with arm pump. 

We all crash. Sometimes hard, and sometimes even harder! All Leatt helmets feature 360 ̊ Turbine Technology. This design utilizes a network of small discs constructed of a non-Newtonian, energy-absorbing material. Because these Turbines can move 360 ̊ (omnidirectional), this technology has two exclusive advantages: namely the reduction of rotational acceleration to the head and brain and the absorption of energy upon impact at concussion level.
