Its varied thickness shell construction employs a thermo-injected polymer blend that seamlessly integrates impact resistance with minimal weight, ensuring riders stay protected without feeling weighed down. The impact-resistant outer shell is crafted from durable thermoplastic, while the inner shell features a composite fiber layer sandwiched between the outer shell and the EPS liner, providing maximum impact absorption and structural integrity. This thoughtful construction enhances rider safety during challenging terrains and high-impact situations. The helmet's fit is highly adjustable, thanks to customizable crown and cheek pads, allowing for a secure and comfortable fit tailored to individual head shapes. The interior boasts a multiple density EPS liner with five different densities, strategically placed to optimize impact management while reducing overall weight, complemented by a polished inner liner with a special coating that minimizes friction and rotational impact forces. The helmet's design minimizes oblique impact effects, with engineered surfaces and coatings that help reduce rotational acceleration during crashes. Ventilation is a highlight of the SM3, featuring ten inlet ports and seven exhaust vents that promote maximized airflow and heat transfer, complemented by a visor designed to channel air into the vents for improved cooling. The visor release system is engineered to trigger with a pre-determined force, reducing neck stress during impacts. Comfort is further enhanced with a recycled material-based liner and integrated hydration channels within the cheek pads, facilitating hydration without sacrificing performance. The chin strap is a 25 mm soft textile design, ensuring both safety and comfort, while the Emergency Release System and removable cheek pads allow for safe helmet removal if necessary. The 3D contoured foam lining provides added comfort during extended rides, and stainless steel D-rings guarantee a secure fit. Overall, the Alpinestars SM3 Helmet offers a well-balanced combination of advanced impact protection, ventilation, and rider comfort, making it an ideal choice for offroad enthusiasts seeking reliable gear.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eVaried thickness shell construction with thermo-injected polymer blend for optimal impact protection and lightweight performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImpact-resistant outer shell made from durable thermoplastic\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInner shell with composite fiber layer for maximum impact absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable fit with customizable crown and cheek pads\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMultiple density EPS liner with five densities for effective impact management\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePolished inner EPS liner with friction-reducing coating for rotational impact protection\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\u003eVentilation system with ten inlets and seven exhaust ports for superior airflow and heat transfer\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVisor designed to direct airflow into vents, enhancing cooling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVisor release system engineered to reduce neck forces during impact\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComfort liner made from recycled materials for eco-friendly protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIntegrated hydration channels within cheek pads for convenience\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSoft 25 mm textile chin strap for comfort and safety\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\u003eStainless steel D-rings for secure fit\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cdiv class=\"product-template\"\u003e\n\u003cbr\u003e      \u003ch1\u003eAlpinestars SM3 Helmet Radium Matte Gray\/Black\/Yellow Fluo Medium - Lightweight Offroad and MX Protection\u003c\/h1\u003e\n\u003cbr\u003e      \u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003eThe Alpinestars SM3 Helmet (Part Number: 8300826-9510-M) is designed for riders who demand superior impact protection combined with lightweight comfort, optimized specifically for motocross, enduro, and offroad activities.
