Alpinestars SM3 Force Helmet — Size M, Cyan

Engineered for motocross, enduro and off‑road use, this helmet combines ease of use, comfort and impact performance.

The thermo‑injected shell employs a special polymer blend with variable wall thickness to deliver an optimal balance of impact protection and light weight.

A patented low‑friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts, creating a slip plane that mimics the brain's natural cerebrospinal fluid.

The visor release system is patented to ensure visor release at a predetermined force, effectively reducing neck loads during an impact.

Ventilation is maximized with 10 inlets and 7 exhaust ports for high heat transfer and airflow.

Material composition (approx.): 48% acrylonitrile‑butadiene‑styrene, 20% polyurethane, 16% polystyrene (EPS), 6% polypropylene, 4% polyvinyl chloride, 2% ethylene‑vinyl acetate, 2% steel, 1% expanded polypropylene, 1% polyamide.
