Alpinestars SM3 Jettson Helmet — XS, Gray, Gloss

The SM3 Jettson helmet is engineered for motocross, enduro and off‑road riding, with innovations focused on ease of use, comfort and impact performance.

Its thermo‑injected shell uses a special polymer blend with variable thickness to balance lightweight design and impact protection.

An innovative low‑friction liner coating creates a slip plane to reduce rotational acceleration from oblique impacts, mimicking the brain's natural cerebrospinal fluid protection.

A patented visor release system ensures the visor releases at a pre‑determined force to help reduce neck loads in an impact.

Ten inlets and seven exhaust ports maximize ventilation and heat transfer to keep the rider cool.
