The Alpinestars Supertech helmet family was engineered to be the most advanced, protective, and performance-enhancing helmet for riders worldwide. The S-M10 offers an optimal balance of ventilation, comfort, and lightweight design without compromising protection. Its aerodynamic profile is smooth and free of external channels that could increase load during an impact or compromise structural integrity. The shell's curvature is designed to reduce friction upon impact, allowing for deflection and efficient energy transfer to protect the rider's head from direct forces and stress to the neck and spine. It features a double D closure and meets ECE 22.06 standards. Weight is 1260g for size Medium (1310g with side padding and 1370g with visor extension).
