Alpinestars Youth SM3 Solid Helmet — S, Black matte

The Youth SM3 Solid Helmet is anatomically engineered and profiled specifically for youth and younger riders, optimized for motocross, enduro, and off‑road use. 🏁

Its lightweight thermo‑injected shell uses a specially formulated polymer blend with variable thickness to deliver an optimal balance of impact protection and low weight, with a typical weight of approximately 1060 g.

The fit can be tailored via crown and cheek pads sold as spare parts; medium and large youth sizes share the same EPS so a medium can be converted to a large as the rider grows, while the small youth uses a smaller EPS and is customizable via cheek pads only.

A multiple‑density inner liner places the correct density in the right area for enhanced impact absorption while helping to reduce overall weight.

A patented low‑friction coating is applied to the inner surface of the main EPS liner to act as a slip plane and reduce rotational acceleration from oblique impacts.

The visor release system is designed to release with a predetermined force to reduce neck loads during an impact, and an emergency release system with removable cheek pads allows safe helmet removal while the helmet is still on.

Comfort features include a recycled‑material comfort liner, integrated hydration tube channels in the cheek pads, a soft 25 mm textile chin strap, and stainless‑steel D‑rings for a secure fit.

Ventilation is maximized with ten inlets and seven exhaust ports, and the visor is shaped to direct airflow into the ports for improved heat exchange and rider comfort. 🌀
