Off-road fiberglass helmet with adjustable peak, double D-ring closure, and removable and washable interior lining.

The S-M7 helmet is designed for off-road racing and is optimized to offer the perfect combination of superior ventilation and comfort in a lightweight helmet, while its extremely aerodynamic composite shell provides exceptional impact protection. In addition to Alpinestars' patented A-Head Fit and Visor Detaching systems, the S-M7 features innovative PLASMA technology on the lower edge of the shell for optimal energy dissipation in the event of contact with the collarbone.

Aerodynamic Design: The S-M7's aerodynamic profile design provides a smooth, aerodynamic shell, free of external channels and elements that could act as load points in the event of an impact or compromise the overall integrity of the helmet's structure.
Energy-Diverting Design: The helmet's curved shell is designed to reduce aerodynamic drag and divert impact forces away from the head, helping to protect the skull, neck, and spine in the event of a crash. PLASMA Inside: Alpinestars' patented PLASMA technology is strategically integrated into the S-M7's side padding for high-performance impact absorption in a critical area, significantly reducing the risk of injury.
A-Head Technology: Alpinestars' patented A-Head adjustment system allows for easy adjustment of the helmet's angle and height for an optimal fit.
Patented Visor Release System: The S-M7's patented visor release system is designed to release in the event of a crash, reducing the risk of helmet damage or rotational injury.
The S-M7's visor is designed to automatically release from the shell when subjected to an impact energy greater than 15 Joules, providing optimal impact protection regardless of direction.
Shell Size for Optimal Fit: The S-M7's shell sizing solution ensures each helmet size offers the most anatomical solution for the wide range of fit needs around the world. It offers three different shell sizes and six consumer sizes from XS to XXL to ensure cyclists get the correct fit, which not only improves comfort and reduces overall weight, but more importantly, improves the helmet's effectiveness in the event of an impact.
Hydration System Ready: The helmet features integrated channels on both sides to accommodate a hydration system.
