Alpinestars SM3 Force Helmet — XS, Cyan

The helmet is engineered for MX, enduro and off‑road use, featuring innovations optimized for ease of use, comfort and impact performance.

Its thermo-injected shell uses a special polymer blend with varying shell thicknesses to balance impact protection and light weight.

A patented low friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts, acting as a slip plane similar to the brain’s cerebrospinal fluid.

A visor release system ensures the visor detaches under a pre-determined force to help reduce neck loads during an impact.

Ventilation is maximized with ten inlets and seven exhaust ports for high heat transfer and airflow.

Materials: 48% acrylonitrile-butadiene-styren, 20% polyurethane, 16% polystyrene (EPS), 6% polypropylene, 4% polyvinyl chloride, 2% ethylene-vinyl acetate, 2% steel, 1% expanded polypropylene, 1% polyamide.
