Why We Like The MTB 4.0 AllMtn Helmet

Brush up on your history of Leatt, and you'll discover a rich past based upon the creation of safer, smarter equipment for those that ride off-road. The California-based brand's two decades of experience has provided us with reliable gear from body armor to neck braces, and the MTB 4.0 AllMtn Helmet is their latest launch to offer superior protection at an affordable price. Its rugged frame is built from a lightweight polymer compound to reduce neck fatigue as you grind up the mountain, and EPS foam handles higher speed impacts no matter where the trail takes you. We especially like Leatt's 360-degree Turbine Technology, which dramatically reduces harmful rotational and low-G impact forces.
