Its shell features a varied thickness construction, utilizing a thermo-injected polymer blend that optimizes impact resistance while minimizing weight. The impact-resistant outer shell is crafted from durable thermoplastic, and the inner shell incorporates a composite fiber layer positioned between the outer shell and EPS liner for enhanced impact absorption. This design ensures superior protection during high-intensity MX, Enduro, and offroad riding. The helmet's fit can be easily adjusted with tailored crown and cheek pads, providing a secure and comfortable fit for various head shapes. The multiple-density inner liner, with five distinct foam densities, ensures impact is absorbed precisely where needed, reducing fatigue and increasing rider safety. Additionally, the polished EPS liner features a special coating to minimize friction, aiding in rotational impact management and further enhancing safety during oblique impacts. Ventilation is prioritized with ten inlet vents and seven exhaust ports, complemented by a visor designed to channel airflow into these ports, improving heat transfer and rider comfort during extended rides. The visor release system is engineered to release with a predetermined force, reducing strain on the rider's neck during impacts. Comfort is further enhanced with a liner made from recycled materials, reflecting Alpinestars' commitment to sustainability. Integrated channels for hydration tubes within the cheek pads offer convenience without compromising safety. The soft, 25 mm textile chin strap ensures a snug fit, while the helmet's emergency release system and removable cheek pads facilitate safe and quick removal if necessary. The 3D contoured foam inside provides a comfortable fit, and the chin area is optimized for impact performance. Stainless steel D-rings secure the helmet tightly, ensuring maximum safety. Designed for serious offroad use, the Alpinestars SM3 Radium helmet offers a blend of advanced safety features, ventilation, and rider comfort, making it an ideal choice for demanding MX and Enduro riders seeking premium protection in a lightweight package.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eVaried thickness thermo-injected shell for optimized impact protection and lightweight performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImpact-resistant thermoplastic outer shell enhances durability and safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComposite fiber inner shell provides maximum impact absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable crown and cheek pads for a tailored fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMultiple density EPS liner with five foam densities for precise impact management\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePolished EPS liner with friction-reducing coating for rotational impact control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEngineered surfaces to minimize oblique impact effects\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaximum ventilation with ten inlet and seven exhaust ports for superior airflow\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVisor designed to channel air into vents, enhancing heat transfer and rider comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVisor release system designed to reduce neck strain during impact\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComfort liner made from recycled materials for sustainability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIntegrated hydration tube channels within cheek pads for convenience\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSoft 25 mm textile chin strap for safety and comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEmergency Release System and removable cheek pads for safe helmet removal\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e3D contoured foam for enhanced rider comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChin area optimized for impact performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStainless steel D-rings for a secure fit\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cdiv class=\"product-template\"\u003e\n\u003cbr\u003e      \u003ch1\u003eAlpinestars SM3 Radium Helmet - Gloss Black\/Red Fluo\/White, Large\u003c\/h1\u003e\n\u003cbr\u003e      \u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003eThe Alpinestars SM3 Radium Helmet is engineered for offroad enthusiasts, combining advanced impact protection with lightweight comfort.
