The Alpinestars SM3 Helmet is engineered for motocross, enduro, and offroad enthusiasts seeking optimal protection combined with lightweight comfort. Featuring a thermo-injected shell with varied thicknesses, this helmet provides superior impact resistance while maintaining a lightweight profile, making it ideal for high-performance riding. The impact-resistant outer shell is crafted from durable thermoplastic, while the inner shell incorporates a composite fiber layer positioned between the outer shell and EPS liner, enhancing impact absorption without adding unnecessary weight.
Inside, the helmet utilizes a multi-density liner system, including a six-piece EPS liner with five different densities designed to manage impact forces effectively across critical zones. The polished inner EPS liner is coated to reduce friction and improve rotational impact management, minimizing the effects of oblique impacts. The helmet’s fit can be customized through adjustable crown and cheek pads, ensuring a secure and comfortable fit for riders of various head shapes. Additionally, the helmet features a low-friction coating on the inner EPS liner, which helps reduce rotational acceleration during impacts, providing enhanced protection. Ventilation is optimized with ten inlet vents and seven exhaust ports, complemented by a visor designed to channel air into these ports for maximum airflow. The visor release system is engineered to release with a predetermined force, reducing strain on the rider's neck during a crash.
Designed with rider safety and comfort in mind, the SM3 Helmet includes an emergency release system and removable cheek pads, allowing for safe and easy removal while still wearing the helmet. The interior comfort liner is made from recycled materials, promoting a lower carbon footprint. Integrated channels inside the cheek pads facilitate hydration tube routing for hydration during rides. The soft textile chin strap ensures a secure fit, while stainless steel D-rings provide reliable fastening. The helmet’s chin area is specifically optimized for impact performance, and the visor is engineered for durability and airflow enhancement, directing air into the helmet’s ventilation system. Overall, the Alpinestars SM3 Helmet offers a blend of advanced safety features, lightweight construction, and rider-focused comfort for demanding offroad adventures.
