Off-road helmet engineered for MX and enduro with thermo-injected shell, low-friction liner and optimized ventilation.
Designed for MX, enduro and off-road riding, the SM3 Force Helmet balances ease of use, comfort and impact performance. 🏁
Thermo-injected shell uses a special polymer blend with varying thickness to optimize impact protection while keeping weight low.
A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration forces from oblique impacts, acting as a slip plane similar to the brain's cerebrospinal fluid. 🧠
Patented visor release system ensures the visor releases at a predetermined force, helping to reduce neck loads during an impact.
Maximized ventilation with 10 inlets and 7 exhaust ports provides efficient heat transfer and airflow for long off-road sessions.
