Off-road helmet engineered for MX and enduro use with advanced shell construction, low-friction EPS liner, patented visor release and optimized ventilation.
Bank transferThe S-M3 Helmet is engineered for MX, Enduro and off-road use, featuring innovations and technologies optimized for ease of use, comfort and impact performance.
Shell construction features a thermo-injected shell made from a special polymer blend with varying thicknesses to deliver an optimal combination of impact protection and light weight.
An Alpinestars-patented low friction coating is applied to the inner EPS liner to reduce rotational acceleration forces that can result from certain oblique impacts.
This layer acts as a slip plane to mimic the brain's own low-friction cerebrospinal fluid, the body's natural defense against oblique impacts.
The patented visor release system ensures the visor releases at a predetermined force, effectively reducing forces on the neck during an impact.
Maximized ventilation and high levels of heat transfer are achieved through 10 inlets and 7 exhaust ports for continuous airflow.
Materials: 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.
