The S-M3 helmet is engineered for MX, Enduro, and Off-road use, featuring a range of technologies and innovations optimized for ease of use, comfort, and impact performance.
Features:
DOT Inner Shell: The S-M3 helmet conforms to both DOT certification and ECE 22.06 homologation for worldwide use
Visor Detaching System: Patented visor release system ensures the visor releases with a predetermined amount of force, effectively reducing forces on the rider's neck during an impact
Ventilation: Maximized ventilation and high heat transfer thanks to 10 inlet and 7 exhaust ports
Innovative Friction Coating: Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce rotational acceleration forces from oblique impacts, acting as a slip plane that mimics the brain's low-friction cerebrospinal fluid, the body's natural defense against such impacts
Lightweight Outershell: This lightweight helmet features a thermo-injected shell made from a special polymer blend with varying thicknesses, engineered to deliver an optimal combination of impact protection and light weight
