Alpinestars SM3 Force Helmet — L, White

Engineered for motocross, enduro and off‑road use, this helmet incorporates innovations optimized for ease of use, comfort and impact performance.

Thermo-injected shell construction uses a special polymer blend with varying thicknesses to deliver an optimal balance of impact protection and low weight.

A patented low-friction coating is applied to the inner surface of the main EPS liner to reduce rotational acceleration from oblique impacts.

This slip-plane layer mimics the brain's low-friction cerebrospinal fluid, the body's natural defense against oblique impacts.

The patented visor release system ensures visor detachment at a controlled force, helping reduce neck loads during an impact.

Ventilation is maximized with ten inlets and seven exhaust ports for efficient heat transfer and airflow management.
