Leatt Helmet MTB 4.0 V21

Super Ventilated Full Face Head and Brain Protection

Renowned for its ventilation and comfort, this all-purpose MTB helmet is fitted with 360 Turbine technology, offering great protection at a fair price.

This fully ASTM DH-certified helmet is the go-to helmet for enduro and bike park riders. Uphill, downhill, upside down, E-bike, or trail—you name it, the DBX 4.0 has you covered. The full-face design with removable chinguard offers outstanding ventilation, and its convenient Fidlock buckle makes life just peachy!

Featuring 360° Turbine Technology, the helmet is lined with turbines which are 360° moving discs constructed from an energy-absorbing shape and material. This tech has two exclusive advantages: the reduction of rotational acceleration to the head and brain, and the absorption of energy upon impact at concussion level.
