The Alpinestars Youth SM3 Helmet is designed for young riders who need dependable impact protection, comfortable fit, and effective ventilation during off-road riding. This solid matte black helmet features a thermo-injected shell made from a technologically advanced, impact-resistant thermoplastic polymer blend. Varying shell thicknesses help balance protection and weight, while the multiple-density inner liner places the appropriate level of energy absorption in key areas of the helmet.
Engineered surfaces on the inner and outer shell help minimize the effects of oblique impacts. A low-friction coating on the main EPS liner functions as a slip plane to help reduce rotational acceleration forces during certain angled impacts. Ten intake vents and seven exhaust ports promote airflow and heat transfer, while the visor is shaped to direct air into the ventilation system. The visor release system is calibrated to release at a predetermined force, helping reduce forces transferred to the rider’s neck during an impact.
The Youth SM3 can be tailored to the rider’s head with replaceable crown and cheek pads available in different thicknesses. Its recycled-material comfort liner supports a lower-impact manufacturing approach, while integrated hydration tube channels in the cheek pads add convenience for extended rides. A soft 1-inch chin strap, stainless steel D-rings, and a secure adjustable fit help provide comfort and stability. The Emergency Release System and removable cheek pads allow the pads to be removed more safely and easily while the helmet remains in place. The 3D-contoured foam further supports rider comfort. This large Alpinestars youth helmet is identified by manufacturer part number 8302225-110-YL and vendor part number 8302225-110-YL.
