Alpinestars Sm3 Radium Off-road Helmet

The Alpinestars SM3 Radium Helmet is meticulously engineered for the demands of MX, Enduro, and off-road riding. Packed with innovations and advanced technologies, the SM3 focuses on user-friendliness, exceptional comfort, and superior impact performance to keep you safe on every ride.

Description

This helmet features a thermo-injected shell constructed from a special polymer blend. This carefully engineered design incorporates varying degrees of thickness to achieve the optimal balance between lightweight construction and robust impact protection. The innovative, patented low-friction coating applied to the inner EPS liner minimizes rotational acceleration forces resulting from oblique impacts. This slip plane mimics the brain's natural cerebrospinal fluid, providing an additional layer of defense against rotational injuries. The patented visor release system ensures the visor detaches with the correct pre-determined force, mitigating the forces transferred to the neck during an impact. With 10 intake vents and 7 exhaust ports, the helmet provides maximum ventilation, facilitating efficient heat transfer and keeping you cool under pressure. Stay protected and comfortable with the Alpinestars SM3 Radium helmet.
