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

The Youth SM3 Wurx Helmet is anatomically engineered for younger riders and optimized for motocross, enduro and off‑road use.

The thermo-injected shell features a special polymer blend with variable thickness to deliver an optimal balance of impact protection and low weight, with an approximate weight of 1060 g.

A multiple-density inner liner places the correct foam density where it’s needed for improved energy absorption and reduced overall mass.

An inner low-friction layer on the main EPS liner helps reduce rotational acceleration during oblique impacts by mimicking the brain’s natural slip plane.

Crown and cheek pads allow a tailored fit; pads are available as spare parts in different thicknesses so growing riders can adjust fit over time.

Youth Medium and Youth Large share the same EPS size to enable conversion via pad changes, while Youth Small uses a smaller EPS and is customizable via cheek pads only.

The helmet includes a visor release system engineered to release with a predetermined force to reduce loads on the neck, plus an emergency release system to permit safe cheek pad removal while worn.

Comfort liner is made using recycled materials for a reduced carbon footprint, and integrated hydration tube channels are provided within the cheek pads.

Ventilation performance is maximized through 10 inlets and seven exhaust ports, with the visor designed to channel air into the ventilation paths.

Soft 25 mm chin strap and secure D-ring closure complete the safety-focused design. 🏁
