Expertly designed for MX and Enduro riding, the S-M3 Heat Helmet is an all-new off-road head protector engineered to deliver the optimal balance of impact protection and lightweight performance. Featuring an advanced thermo-injected shell and a patented low-friction internal coating, it effectively reduces rotational acceleration forces during oblique impacts. This ECE 22.06 certified helmet includes a multi-density EPS liner, integrated hydration tube channels, and an emergency release system for maximum rider safety and comfort.

Key features

Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and varying thicknesses, engineered for an optimal balance of impact protection and a lightweight feel (1430g ECE / 1460g DOT).
Maximized Ventilation: High levels of heat transfer and cooling airflow provided by 10 intake inlets and seven exhaust ports.
Rotational Acceleration Force Protection: Patented low-friction coating on the inner EPS liner acts as a slip plane to reduce rotational forces during oblique impacts, mimicking the brain's natural protection.
Patented Visor Release: Ensures the visor detaches with a pre-determined force during an impact to effectively reduce stress and potential injury to the rider's neck.
