ALPINESTARS(MX) SM3 Solid Helmet — M, Black

The SM3 helmet is engineered for MX, enduro and off-road use, featuring innovations optimized for ease of use, comfort and impact performance. 🛡️

Its thermo-injected shell incorporates a special polymer blend with varying thicknesses to deliver an optimal combination of impact protection and light weight.

A patented low-friction coating applied to the inner EPS liner reduces rotational acceleration forces from oblique impacts by acting as a controlled slip plane that mimics the brain’s cerebrospinal fluid. 🧠

The helmet includes a patented visor release system that ensures the visor releases at a predetermined force, helping to reduce forces on the neck during an impact.

Maximized ventilation and high heat-transfer exchange are achieved through 10 inlets and 7 exhaust ports for consistent airflow and comfort.
