Alpinestars SM3 Jettson Helmet — L, Gray, Gloss

The SM3 Jettson 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 uses a special polymer blend with variable thickness to deliver an optimal balance of impact protection and lightweight feel.

An innovative low-friction coating is applied to the inner surface of the main EPS liner to reduce rotational acceleration from oblique impacts, mimicking the brain's natural cerebrospinal fluid slip plane.

A patented visor release system ensures the visor releases at a predetermined force to reduce neck loads during an impact.

Ten inlets and seven exhaust ports provide maximized ventilation and efficient heat transfer for long riding sessions.
