This XL helmet features a gloss yellow fluo and black finish and uses a lightweight, impact-resistant thermoplastic outer shell with varied thickness construction. The SM3 combines targeted protection, ventilation, and rider comfort for demanding off-road applications. Manufacturer part number 8301026-5011-XL and vendor part number 8301026-5011-XL identify this specific configuration.\u003c\/p\u003e\u003cp\u003eAlpinestars uses a composite fiber layer between the outer shell and EPS liner to enhance impact protection while helping control overall weight. The six-piece EPS liner incorporates five densities to manage impact energy in targeted areas. A low-friction coating on the inner EPS liner and engineered inner and outer surfaces help reduce rotational acceleration associated with certain oblique impacts. The visor release system is designed to release at a predetermined force to help reduce stress on the rider’s neck during an impact.\u003c\/p\u003e\u003cp\u003eVentilation is supported by ten intake ports and seven exhaust ports, while the visor helps direct airflow into the helmet. The crown and cheek pads allow the fit to be tailored to the rider, and the removable cheek pads support the integrated Emergency Release System for safer helmet removal. The comfort liner uses recycled materials, and integrated hydration tube channels in the cheek pads add convenience during extended rides. A soft 1-inch chin strap and stainless steel D-rings provide secure, comfortable retention.\u003c\/p\u003e\u003cp\u003eThe Alpinestars SM3 Heat XL is intended for riders seeking a performance-focused helmet for motocross, enduro, and off-road use.
