ALPINESTARS(MX) SM3 Force Helmet — Size S, Black

Engineered for MX, enduro and off-road riding, this helmet balances ease of use, comfort and impact performance. 🏁

The thermo-injected shell uses a specially blended polymer with variable thickness to provide impact protection while keeping weight low.

A patented low-friction coating on the inner EPS liner helps reduce rotational acceleration from oblique impacts.

This slip-plane layer is designed to mimic the brain's cerebrospinal fluid, helping to mitigate forces during angled impacts.

The visor features a patented release system that disengages at a predetermined force to reduce neck loads in an impact.

Ten inlets and seven exhaust ports maximize ventilation and heat transfer for excellent airflow and rider cooling.

Multimaterial construction and tuned energy-absorbing liners deliver durability and resilience for off-road scenarios. ⚙️
