Off-road helmet engineered for MX and enduro with advanced impact management, low-friction slip-plane technology and high ventilation.
SM3 Solid Helmet 🪖 engineered for MX, enduro and off-road use with innovations optimized for comfort, ease of use and impact performance.
Shell construction features a thermo-injected shell incorporating a special polymer blend with varying thickness, engineered to deliver an optimal combination of impact protection and light weight.
A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration forces from certain oblique impacts, creating a slip plane that mimics the brain's natural cerebrospinal fluid defense.
The patented visor release system ensures visor release at a predetermined force, effectively reducing forces on the neck during an impact.
Ventilation and heat transfer are maximized via 10 inlets and 7 exhaust ports for efficient airflow.
