This medium helmet features a lightweight, impact-resistant thermoplastic shell made with a specialized polymer blend and varying shell thicknesses to balance protection and weight. The Alpinestars SM3 also uses a multiple-density EPS inner liner, positioning the appropriate density in key areas to improve impact absorption and help reduce overall helmet weight.\u003c\/p\u003e\u003cp\u003eEngineered for modern impact performance, the helmet’s inner and outer surfaces help minimize the effects of oblique impacts. A low-friction coating on the primary EPS liner creates a slip-plane effect intended to reduce rotational acceleration forces associated with certain angled impacts. The visor release system is designed to release at a predetermined force, helping reduce the load transferred to the rider’s neck during an impact. Ten intake vents and seven exhaust ports support high levels of airflow and heat exchange, while the visor helps direct air into the ventilation system for improved circulation.\u003c\/p\u003e\u003cp\u003eFit and comfort can be customized with replaceable crown and cheek pads available in different thicknesses. The recycled-material comfort liner helps reduce environmental impact, while integrated hydration tube channels in the cheek pads provide convenient routing for hydration systems. A 25-millimeter soft textile chin strap, stainless steel D-rings, and a secure retention system help maintain a stable fit. The Emergency Release System and removable cheek pads allow safer, easier removal while the helmet remains on the rider. The Alpinestars Youth SM3 Radium is finished in Gloss Yellow Fluo, Black, and Blue and is identified by manufacturer and vendor part number 8301825-5017-YM.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYouth Medium Fit: Designed for young riders requiring a secure and comfortable medium helmet fit\u003c\/li\u003e\n\u003cli\u003eRadium Colorway: Gloss Yellow Fluo, black, and blue finish for a distinctive off-road appearance\u003c\/li\u003e\n\u003cli\u003eThermoplastic Shell: Lightweight impact-resistant outer shell uses a specialized polymer blend with varied thicknesses\u003c\/li\u003e\n\u003cli\u003eMultiple-Density EPS Liner: Uses targeted liner densities to support impact absorption and reduce overall weight\u003c\/li\u003e\n\u003cli\u003eOblique Impact Design: Inner and outer surfaces are engineered to help minimize the effects of angled impacts\u003c\/li\u003e\n\u003cli\u003eLow-Friction EPS Coating: Slip-plane layer is designed to reduce rotational acceleration forces from certain oblique impacts\u003c\/li\u003e\n\u003cli\u003eVentilation System: Ten intake vents and seven exhaust ports promote airflow and heat exchange\u003c\/li\u003e\n\u003cli\u003eVisor Release System: Predetermined-release design helps reduce forces transferred to the rider’s neck during an impact\u003c\/li\u003e\n\u003cli\u003eAdjustable Interior Fit: Replaceable crown and cheek pads are available in different thicknesses for personalized fit\u003c\/li\u003e\n\u003cli\u003eHydration Tube Channels: Integrated routing channels in the cheek pads support convenient hydration system use\u003c\/li\u003e\n\u003cli\u003eEmergency Release System: Removable cheek pads allow easier and safer helmet removal while the helmet is worn\u003c\/li\u003e\n\u003cli\u003eSecure Retention: Soft 25-millimeter textile chin strap and stainless steel D-rings provide a dependable fit\u003c\/li\u003e\n\u003cli\u003eManufacturer: Alpinestars\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 8301825-5017-YM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":67564653314283,"sku":"01111639","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/4036161.png?v=1790783437","url":"https:\/\/ctracingservices.com\/products\/alpinestars-youth-sm3-radium-helmet-gloss-yellow-fluo-black-blue-medium-8301825-5017-ym","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
