The SM3 Helmet is engineered for MX, Enduro and off-road use, featuring innovations and technologies optimized for ease of use, comfort and impact performance. 🏁
Shell construction features a thermo-injected shell with a special polymer blend and variable thicknesses to deliver an optimal balance of impact protection and light weight.
Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce rotational acceleration forces from certain oblique impacts by acting as a slip plane that mimics the brain's cerebrospinal fluid. 🧠
The patented visor release system ensures visor release at a predetermined force to help reduce forces on the neck during an impact.
Maximized ventilation and high heat transfer are achieved through 10 inlets and 7 exhaust ports to keep riders cool in demanding conditions. 🌬️
