Alpinestars S-M7 Blaster Helmet

The S-M7 Helmet is engineered for off-road racing, and is optimized to offer the perfect blend of superior ventilation and comfort in a lightweight helmet, while its supremely aerodynamic composite shell delivers exceptional impact protection. In addition to Alpinestars' patented A-Head Fitment and Visor Detaching Systems, the S-M7 is equipped with innovative PLASMA technology at the lower side of the shell edge for optimum energy dissipation in case of contact with the collarbone area.

• Aerodynamic Design: The S-M7's aerodynamic profile design offers a smooth, streamlined shell free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet's construction.
• A-Head Technology: Alpinestars patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head for an optimized performance fit.
• Patented Visor Release: The S-M7's patented Visor Release System is designed to detach during a crash, reducing the risk of helmet damage or rotational injury.
• Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber for the optimum blend of impact protection and force dissipation, sliding performance, energy absorption, stability and durability.
• Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum ventilation.
• Lightweight: ECE 1280g and DOT 1340g for a size medium.
