Dominate the trail with the Leatt MTB 4.0 V21, a full-face helmet engineered for riders who demand uncompromising safety and aerodynamic efficiency. Designed specifically for mountain biking, this helmet features an advanced MIPS technology layer that rotates independently of your head to dissipate rotational energy during glancing blows, significantly reducing the risk of concussions. The sleek, aggressive profile cuts through the air, minimizing drag at high speeds while the integrated visor shields your eyes from debris and sun glare. With a secure fitment system and premium ventilation channels, you stay cool and focused regardless of the terrain's intensity.
