ALPINESTARS(MX) SM3 Solid Helmet — M, Black

Designed for MX, enduro and off‑road riding, this helmet blends ease of use, comfort and high impact performance.

The thermo‑injected shell uses a special polymer blend with variable thickness to provide optimal impact protection while staying lightweight.

A patented low‑friction coating on the inner EPS liner reduces rotational acceleration from oblique impacts by acting as a slip plane similar to the brain’s cerebrospinal fluid.

The visor release system is engineered to release at a predetermined force, helping reduce neck loads during an impact.

Maximized ventilation with 10 inlets and 7 exhaust ports ensures efficient heat transfer and airflow.

Construction materials include acrylonitrile‑butadiene‑styrene, polyurethane, polystyrene (EPS), polypropylene, polyvinyl chloride, ethylene‑vinyl acetate, steel, expanded polypropylene and polyamide. 🚵‍♂️
