The S-M3 helmet is engineered for MX, Enduro andOff-road use, and features a whole raft of technologiesand innovations optimized for ease of use, comfort andimpact performance.

• Patented visor release system ensures the visor is released with the correctpredetermined amount of force, effectively reducing theforces on the riders neckduring an impact.
• Maximized ventilation and high levels of heat transferexchange thanks to 10 inlets and 7 exhaust ports.
• Alpinestars patented low friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certainoblique impacts. This layer essentially acts as a slipplane to mimic the brains own low friction cerebrospinal fluid, which is the bodys natural defense againstoblique impacts.
• This lightweight helmet features a thermo-injectedshell incorporating a special polymer blend enhanced byvarying degrees of thickness that is engineered todeliver the optimal combination of impact protection andlight weight.
