The Alpinestars Youth SM3 Helmet is a lightweight off-road helmet designed to provide young riders with dependable impact protection, ventilation, and a secure, comfortable fit. This solid matte black helmet features a thermo-injected outer shell made from an advanced impact-resistant thermoplastic polymer blend. The shell uses varied thicknesses to balance protection and weight, while the multiple-density inner liner places the appropriate material in key areas to help absorb impact energy.
Designed for enhanced protection during angled impacts, the Alpinestars Youth SM3 Helmet incorporates low-friction surfaces on the inner and outer structure. A low-friction coating on the main EPS liner helps reduce rotational acceleration forces by creating a slip-plane effect. The visor release system is engineered to release at a predetermined force, helping reduce stress on the rider’s neck during an impact. Stainless steel D-rings provide a secure closure, and the 25 mm soft textile chin strap supports all-day comfort.
Ventilation is optimized through ten intake ports and seven exhaust ports, with the visor directing airflow into the helmet for improved heat transfer. The recycled-material comfort liner supports reduced environmental impact, while removable cheek pads and an Emergency Release System allow safer, easier helmet removal. Integrated hydration tube channels in the cheek pads add practical convenience for trail and off-road riding. The crown and cheek pads can be replaced with alternate thicknesses to tailor the fit. This Alpinestars Youth SM3 Helmet is size Small, model SM3, brand Alpinestars, manufacturer part number 8302225-110-YS, and vendor part number 8302225-110-YS.
