Purpose-built off-road helmet with thermo-injected shell, low-friction EPS liner, patented visor release, and 10 inlets plus 7 exhaust ports for superior ventilation.
Engineered for MX, Enduro and off-road use, the S-M3 helmet combines ease of use, comfort and impact performance. 🏁
Thermo-injected shell construction uses a special polymer blend with variable thickness to deliver an optimal balance of impact protection and light weight.
A patented low-friction coating on the inner EPS liner reduces rotational acceleration from oblique impacts by acting as a slip plane that mimics cerebrospinal fluid, enhancing brain protection. 🛡️
The patented visor release system ensures the visor releases with a predetermined force to help reduce neck loads during an impact.
Maximized ventilation and efficient heat transfer come from 10 inlets and 7 exhaust ports for sustained airflow and comfort during intense riding. 💨
