Product details
When trail riding reaches the next level and you challenge the mountains, eventually the mountain will call you, so be prepared!
With a universal sunglasses dock, you can securely store your sunglasses under the visor when not in use, protected from scratches and unwanted impacts. The adjustable visor opens wide enough to place your glasses underneath, so you don't have to constantly take them off. You'll also love the comfort of the Fidlock buckle system. Leatt helmets feature 360° turbine technology, which reduces both rotational acceleration and impact energy to the head and brain. Don't hesitate to push your limits. Get ready and prepare for whatever awaits you on the trail.
