Alpinestars SM3 Force Helmet — L, Black

Designed for MX, enduro and off-road use, this helmet integrates innovations focused on ease of use, comfort and impact performance.

The thermo-injected shell employs a special polymer blend with varying thicknesses engineered to deliver an optimal balance of impact protection and reduced weight.

A patented low-friction coating applied to the inner EPS liner reduces rotational acceleration forces that can occur during certain oblique impacts.

This slip-plane layer mimics the brain's cerebrospinal fluid, providing a controlled sliding surface to help mitigate oblique-impact forces.

The patented visor-release system is calibrated to release at a predetermined force, effectively lowering loads on the neck in the event of an impact.

Ventilation is maximized with 10 inlets and 7 exhaust ports to ensure efficient heat transfer and rider comfort.
