Finished in Matte Gray, Black, and Yellow Fluo, this Medium helmet features a lightweight thermo-injected shell made from an advanced impact-resistant thermoplastic. The shell uses a specialized polymer blend with varying thicknesses to help balance strength and reduced weight.\u003c\/p\u003e\u003cp\u003eInside, the Alpinestars Youth SM3 uses a multiple-density EPS liner engineered to provide the appropriate level of impact absorption in key areas. Low-friction surfaces on the inner and outer helmet components are designed to help reduce rotational acceleration during certain oblique impacts. The visor release system is calibrated to release at a predetermined force, helping reduce forces transferred to the rider’s neck in an impact. Ten intake vents and seven exhaust ports promote airflow and heat exchange, while the visor helps direct air into the ventilation system.\u003c\/p\u003e\u003cp\u003eFit and convenience are supported by removable crown and cheek pads, allowing the helmet to be tailored with replacement padding in different thicknesses. The cheek pads include integrated hydration tube channels, and the Emergency Release System allows the pads to be removed safely while the helmet remains in place. A recycled-material comfort liner helps reduce environmental impact, while the soft 1-inch chin strap and stainless steel D-rings provide secure, comfortable retention. The 3D-contoured foam further improves rider comfort during extended use.\u003c\/p\u003e\u003cp\u003eThis Medium Alpinestars Youth SM3 helmet is supplied under manufacturer part number and vendor part number 8301825-9510-YM.
