Aerodynamic composite shell features a smooth, streamlined profile and 20 intake and exhaust ports to optimize airflow and minimize drag. Integrated PLASMA technology in the side pads provides high-performance shock absorption to significantly reduce rotational forces at the collarbone area. Patented A-Head Fitment System allows you to adjust the helmet’s angle and height for a personalized performance-driven fit. Patented Visor Release System automatically detaches on impacts over 15 joules to minimize helmet damage and reduce the risk of rotational injury. Multi-layer fiberglass, carbon, and Aramid shell construction offers ultra-lightweight protection, exceeding ECE 22.06 and DOT standards with over 76% reduction in peak rotational acceleration. Meets Federal Motor Vehicle Safety Standard 218 (FMVSS 218). 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. As well as 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.
