Performance-ready protection for motocross and off-road riding

Meet the Alpinestars SM3 Solid Helmet, crafted for riders who demand both protection and agility on demanding tracks and rugged trails. The thermo-injected shell uses a variable thickness design to help distribute impact energy, supporting a balanced feel between stiffness and pliability. While results can vary by situation, this approach is intended to offer a confident ride through jumps, berms, and rough terrain.
