Alpinestars SM3 Force Helmet — XL, Cyan

Engineered for motocross, enduro and demanding off‑road use, the SM3 Force delivers innovations focused on comfort, usability and impact performance.

The thermo‑injected shell employs a special polymer blend with variable thickness to balance lightweight construction and reliable impact protection.

A patented low‑friction coating is applied to the inner EPS liner to help reduce rotational acceleration forces from oblique impacts.

This low‑friction layer acts as a slip plane, mimicking the brain's natural cerebrospinal fluid to mitigate rotational forces during impacts.

The patented visor release system is engineered to release at a predetermined force, helping to reduce neck loads in a crash scenario.

Ventilation is maximized with 10 inlets and 7 exhaust ports for effective heat transfer, and the multi‑material construction combines engineered polymers and expanded foams for tuned protection and comfort.
