When trail riding moves up to the next level and you are challenging mountains. The mountain will call you at one point or another, so be prepared!

A universal sunglasses dock lets you safely dock your sunglasses under the visor when not in use, protected from scratches and unwanted impacts. The adjustable visor opens up enough to place your goggles underneath, so you don’t have to constantly remove them. You will also love the convenience of the Fidlock buckle system.

Leatt helmets feature 360 ° Turbine Technology that reduces both rotation acceleration and concussion level impact energy to your head and brain! Do not be afraid to push your limits.

Gear up and be prepared for whatever is waiting along the trail.
