This lightweight helmet is designed with the safety and comfort of young riders in mind, providing excellent protection and ventilation.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe SM3 Youth Radium Helmet features a thermo-injected shell made from a special polymer blend with varying thicknesses to optimize impact protection while maintaining a light weight of 1060g. The helmet is available in three youth sizes: Small, Medium, and Large. The inner and outer surfaces are engineered to minimize the effects of oblique impacts, complemented by Alpinestars' patented low friction coating on the EPS liner to reduce rotational acceleration forces. Ventilation is maximized through 10 inlets and seven exhaust ports, ensuring high levels of heat transfer. The comfort liner is constructed using recycled materials, reducing its carbon footprint, and includes hydration tube channels integrated into the cheek pads. Enhanced safety features include an Emergency Release System, removable cheek pads, and a 25mm soft textile chin strap with stainless steel D-rings for a secure fit. Alpinestars has also introduced a new in-house standard for the SM3 Youth to test the helmet’s chin to conditions heavier than the homologation standard.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eThermo-injected shell with special polymer blend offers optimal impact protection and lightweight design.\u003c\/li\u003e\n    \u003cli\u003ePatented visor release system reduces forces on the rider's neck during impact.\u003c\/li\u003e\n    \u003cli\u003eMultiple density inner liner provides enhanced impact absorption and reduces overall weight.\u003c\/li\u003e\n    \u003cli\u003eMaximized ventilation with 10 inlets and seven exhaust ports for superior airflow.\u003c\/li\u003e\n    \u003cli\u003eEmergency Release System and removable cheek pads for safe and easy removal.\u003c\/li\u003e\n    \u003cli\u003eComfort liner made from recycled materials with integrated hydration tube channels.\u003c\/li\u003e\n    \u003cli\u003eEquipped with a 25mm soft textile chin strap and stainless steel D-rings for a secure fit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eBrand: Alpinestars\u003c\/li\u003e\n    \u003cli\u003eModel: SM3 Youth Radium Helmet\u003c\/li\u003e\n    \u003cli\u003eType: MX, Enduro, Off-Road Helmet\u003c\/li\u003e\n    \u003cli\u003eShell Material: ABS\u003c\/li\u003e\n    \u003cli\u003eWeight: 1060g\u003c\/li\u003e\n    \u003cli\u003eSizes: Youth Small, Youth Medium, Youth Large\u003c\/li\u003e\n    \u003cli\u003eVentilation: 10 inlets, 7 exhaust ports\u003c\/li\u003e\n    \u003cli\u003eChin Strap: 25mm soft textile with stainless steel D-rings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eCrown and cheek pads are available as genuine spare parts in different thicknesses to tailor the fit to the rider's head.
