The Alpinestars Supertech family of helmets was engineered to be the most advanced, protective, and performance-enhancing helmets for riders. The S-M10 offers an exceptional balance of ventilation and comfort, with a remarkably lightweight design without compromising protection. Its aerodynamic profile is smooth and streamlined, free of external channels that could cause issues during an impact. The helmet's curved surface is designed to reduce friction upon impact, allowing for deflection and efficient energy transfer to protect the rider's head from direct force and stress on the neck and spine. It weighs 1260g for a size Medium (ECE), 1310g with side padding, and 1370g with the visor extension. Features a Double D closure and meets ECE 22.06 standards.
