The Leatt MTB All Mountain 4.0 MTB Helmet features 360 ̊ Turbine Technology, which reduces both rotational acceleration and impact energy to the head and brain. The universal sunglass holder allows you to securely store your sunnies under the visor when not in use, protecting them from scratches and unwanted bumps. The adjustable visor opens wide enough to place your sunglasses underneath without having to constantly remove them.
