From the uphill pedal to the downhill death grip, the Leatt MTB Enduro 4.0 V21 Bike Helmet is packed with unique features that set it apart from other full face helmets.

Finished with Leatt's safety enhancing 360° Turbine Technology which reduces both rotational acceleration and concussion level impact energy, this helmet is poised to help you take your riding to the next level.
