Off‑road helmet engineered for MX and enduro with advanced shell construction, low‑friction liner, patented visor release and 10 inlets/7 exhaust ports.
🏍️ The S‑M3 helmet is engineered for MX, enduro and off‑road use, featuring technologies optimized for ease of use, comfort and impact performance.
The thermo‑injected shell uses a special polymer blend with varying thicknesses to balance 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 similar to cerebrospinal fluid.
The visor release system is engineered to release with a predetermined force, helping reduce neck forces during an impact.
Maximized ventilation and efficient heat transfer are achieved through 10 inlets and 7 exhaust ports for sustained airflow.
