  • Specifically designed for motocross, enduro, and off-road riding, the S-M3 helmet incorporates innovations and technologies engineered to simplify use, maximize comfort, and provide effective impact protection.
  • Its thermo-injected shell, made from a special multi-thickness polymer blend, is engineered to deliver optimal impact safety while keeping weight low.
  • Inside the main EPS liner, an innovative low-friction coating, patented by Alpinestars, is applied to mitigate rotational forces generated during certain oblique impacts.
  • This layer acts as a true slip plane, mimicking the role of cerebrospinal fluid to better manage and dissipate the energy of oblique impacts.
  • A patented visor release system allows detachment at a predefined force, effectively reducing the loads exerted on the neck in the event of an impact.
  • Airflow is optimized for maximum ventilation and high heat exchange, thanks to 10 intake and 7 exhaust ports strategically placed.
