The SM3 Helmet is engineered for MX, enduro and off-road use, featuring innovations and technologies optimized for ease of use, comfort and impact performance. 🏁
The thermo-injected shell combines a specially formulated polymer blend with variable thickness to deliver an ideal balance of impact protection and lightweight construction.
An Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce rotational acceleration forces from oblique impacts, mimicking the brain's natural cerebrospinal fluid slip plane. 🧠
A patented visor release system ensures the visor releases at a pre-determined force, reducing neck loads during an impact.
Ten inlets and seven exhaust ports maximize ventilation and heat transfer for extended off-road riding comfort.
