ALPINESTARS(MX) Youth SM3 Wurx Helmet — Youth, Size S, Gloss

Designed and profiled specifically for younger riders, the SM3 Youth helmet is optimized for motocross, enduro and off-road use. 🛡️

Thermo-injected outer shell uses a polymer blend with variable thickness to balance impact protection and low weight; the helmet weighs approximately 1060 g.

Available in three shell sizes with tailored crown and cheek pads to adjust fit as the rider grows; spare pads are offered in multiple thicknesses for fit customization.

Youth medium and large share the same EPS size so an intermediate rider can expand fit later, while the youth small uses a smaller dedicated EPS for the smallest riders.

Multiple-density inner liners and engineered inner/outer surfaces help reduce the effects of direct and oblique impacts for enhanced protection.

A patented low-friction layer inside the main EPS liner acts as a slip plane to help minimize rotational acceleration during certain oblique impacts.

Patented visor release and an emergency cheek-pad release system reduce forces on the neck and allow safe pad removal while the helmet remains on.

Comfort features include a soft 25 mm chin strap, stainless steel D-rings, integrated hydration tube channels in cheek pads, and extensive ventilation with 10 inlets and 7 exhaust ports for optimized airflow.
