The AllMtn 3.0 helmet delivers the protection, performance, and comfort you need for challenging trail rides. Leatt’s 360° Turbine Technology works to minimize rotational forces and absorb energy from lower-speed impacts, while the integrated PowerBridge and impact foam offer protection against high-speed collisions, creating a comprehensive 3-in-1 safety system. The lightweight polymer construction features 20 vents for excellent airflow, paired with a moisture-wicking, breathable liner that effectively manages sweat. A Fidlock magnetic buckle enables quick one-handed fastening, and the adjustable breakaway visor adds versatility for tackling rough terrain on extended rides.
