The SM3 Helmet is engineered for MX, Enduro and off-road use, featuring innovations optimized for ease of use, comfort and impact performance. 🛡️
Shell construction features a thermo-injected shell that incorporates a special polymer blend with varying thicknesses to provide an optimal balance of impact protection and light weight.
An Alpinestars patented low-friction coating is applied to the inner surface of the main EPS liner to reduce rotational acceleration forces from certain oblique impacts, acting as a slip plane similar to the brain's own cerebrospinal fluid.
The patented visor release system ensures visor detachment at predetermined force levels, effectively reducing forces on the neck during an impact.
Ventilation is maximized with 10 inlets and 7 exhaust ports to promote high levels of heat transfer and airflow for sustained rider comfort. 🌬️
