ALPINESTARS(MX) SM3 Heat Helmet — XS, Pink, Purple, White

The SM3 Heat Helmet is engineered for MX, enduro and off-road riding, combining comfort, usability and impact performance. 🔥

Its thermo-injected shell uses a blended polymer with variable thickness to balance lightweight feel and protection.

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

That slip-plane layer mimics the brain's natural cerebrospinal fluid, adding a secondary defense against angled impacts.

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

Ventilation is optimized with ten inlets and seven exhaust ports to maximize heat transfer and airflow during intense rides.
