Leatt All-MTN 4.0 Mountain Bike Helmet
Details
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 reduces both rotation acceleration and concussion level impact energy to your head and brain! Do not be afraid to push you limits.
Gear up and be prepared for whatever is waiting along the trail.

Leatt's 360° Turbine Technology not only mitigates rotational acceleration, but also low-velocity linear acceleration that has been shown, if repeated, to have cumulative effects on the frequency and severity of concussion and chronic traumatic encephalopathy (CTE). In short, this brain injury reduction technology significantly reduces the risk of sustaining serious head and brain injuries during a crash.

Sometimes an accident or impact is severe enough to damage your helmet to the extent that it may need to be replaced. This would occur when any of the safety features (such as the impact liner, 360° Turbine Technology, or the helmet shell) are compromised and the helmet is no longer able to function as designed. For your safety, it is essential that you don't continue to use a damaged helmet.
To assist with the cost of a new helmet, Leatt has established a helmet replacement policy. If your helmet suffers any damage that means it cannot work as it should, our global Leatt Helmet Replacement Support partners will offer a great new Leatt helmet 40% discount on the recommended retail price listed in your country. The replacement helmet will be the same model as yours or, if this model is no longer available, the closest equivalent helmet or a better one will be
offered.
