The SM3 Helmet is engineered for MX, Enduro and off‑road use, featuring innovations optimized for ease of use, comfort and impact performance. 🏁
Thermo‑injected shell construction uses a special polymer blend with varying thickness to deliver an optimal balance of impact protection and lightweight performance.
Alpinestars' patented low friction coating on the inner EPS liner reduces rotational acceleration in oblique impacts by acting as a slip plane, mimicking the brain's cerebrospinal fluid. 🧠
Patented visor release reduces neck forces in an impact, while maximized ventilation and heat transfer come from 10 inlets and 7 exhaust ports, keeping riders cool during demanding sessions. 🌬️
