The Alpinestars SM3 Helmet combines advanced safety features with lightweight design to provide optimal protection for motocross, enduro, and off-road riders. The helmet features a thermo-injected shell that incorporates a polymer blend of varying thicknesses, engineered to deliver an ideal balance of impact resistance and weight savings. Its impact-resistant thermoplastic outer shell is complemented by an inner composite fiber layer positioned between the outer shell and EPS liner, enhancing overall impact protection. This construction ensures durability without sacrificing maneuverability during intense riding sessions. The helmet's fit is customizable with adjustable crown and cheek pads, allowing riders to achieve a secure, comfortable fit tailored to their head shape. The multiple-density EPS liner comprises a six-piece design with five different densities, effectively managing impact energy while reducing weight. A polished inner EPS liner with a special coating minimizes friction and rotational forces during oblique impacts, which is crucial for rider safety. The helmet's surfaces are meticulously engineered to mitigate the effects of oblique and glancing blows, offering enhanced protection. Ventilation is optimized through ten intake ports and seven exhaust outlets, facilitating excellent airflow and heat transfer. The visor's design channels air into these ports, further improving airflow and rider comfort. Additionally, the visor release system is engineered to detach with controlled force, reducing strain on the rider’s neck during impact. Comfort is enhanced with a liner made from recycled materials, contributing to a lower environmental footprint. Integrated channels within the cheek pads facilitate hydration tube routing, adding convenience during rides. The chin strap, measuring 25 mm, ensures a snug and secure fit for safety and comfort. The helmet also includes an Emergency Release System and removable cheek pads for quick and safe removal, even during an accident. The 3D contoured foam padding offers a comfortable fit, while the chin area is specifically designed for superior impact performance. Stainless steel D-rings provide a reliable and secure fastening system. Overall, the ALPINESTARS SM3 Helmet delivers a blend of advanced impact protection, lightweight comfort, and rider-focused features, making it an ideal choice for off-road enthusiasts seeking safety and performance.
