ALPINESTARS(MX) SM3 Radium Helmet — L

This helmet is engineered for MX, enduro and off-road use, combining ease of use, comfort and impact performance. 🏁

• Shell construction uses a thermo-injected shell with a specialized polymer blend and variable thickness to deliver an optimal balance of impact protection and light weight.
• An innovative low-friction coating is applied to the inner EPS liner to reduce rotational acceleration from certain oblique impacts by 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 forces on the neck during an impact.
• Maximized ventilation with 10 inlets and 7 exhaust ports provides high levels of heat transfer and consistent airflow.

Engineered for riders who demand protection, ventilation and comfort across technical off-road conditions.
