Alpinestars Supertech S-M5 Sail Motocross Helmet

The SM5 helmet has been purposefully designed to provide MX riders with a safe and optimal protective and comfortable riding experience. Featuring a lightweight, thermo-injected shell that incorporates a special polymer blend enhanced by varying degrees of thickness, the SM5 helmet is engineered to deliver the optimal combination of impact protection and low weight. The five-density EPS liner ensures the correct density in the appropriate areas for enhanced impact absorption.

Constructed from a technologically advanced, impact-resistant thermoplastic in three anatomical shell sizes, the lightweight outer shell is complemented by three individual EPS inner liner sizes. The combination of inner lining and cheek padding offers 6 unique sizes to ensure the best possible fitment and protection for the wearer.

Maximized ventilation and high levels of heat transfer exchange are achieved through the incorporation of multi-air inlets and exhaust ports. The ECE version of the SM5 helmet weighs 1,350 grams for a size medium, while the ECE DOT version with shield weighs 1,420 grams.

The multiple-density inner liner is designed to ensure the correct density in the appropriate areas, providing enhanced impact absorption. The SM5 helmet meets the FMVSS 218 Standard and is ECE/DOT approved, ensuring it delivers the highest levels of protection for MX riders.

In summary, the SM5 helmet has been meticulously engineered to prioritize the safety and comfort of MX riders. Its lightweight, thermo-injected shell, multi-density EPS liner, and advanced ventilation system work in harmony to provide optimal impact protection and a comfortable riding experience.
