We trust Leatt to provide quality protection and coverage for our enduro and mountain bike rides, and that includes the MTB 4. 0 Enduro Helmet. It's known for its ventilation and comfort, and it's the helmet we're grabbing before heading for an enduro ride or a trip to the bikepark. It's fitted with 360 Turbine technology which both lowers the cost and manages protection, and its full-face design still offers breathability. The MTB 4. 0 Enduro Helmet reduces rotational acceleration and absorbs energy upon impact to better protect our heads. We know we're covered if we crash with the MTB 4. 0 Enduro Helmet.
