ALPINESTARS SM5 SAIL HELMET
The Alpinestars SM5 Sail Helmet is purpose-built to meet the high demands of motocross riders, offering an advanced combination of safety, comfort, and lightweight performance. Every detail of its construction reflects Alpinestars’ commitment to rider protection and confidence, whether on the track or rugged off-road terrain.
Crafted with a thermo-injected shell, the SM5 uses a specially formulated polymer blend that is both durable and lightweight. The shell’s structure features strategically varied thicknesses, carefully engineered to optimize strength in high-impact areas while reducing overall weight. This design ensures maximum protection without compromising rider comfort or agility, making it ideal for long and intense riding sessions.
A standout safety feature of the SM5 Helmet is its five-density EPS liner. This advanced impact absorption system uses multiple foam densities positioned throughout the interior to provide tailored protection in key zones. The result is improved energy dispersion during a crash, minimizing the risk of head injury and enhancing overall helmet performance.
Beyond its protective features, the SM5 also focuses on rider comfort and functionality. The interior includes a soft, moisture-wicking liner that is fully removable and washable, allowing for easy maintenance and a fresh feel after every ride. Ventilation ports are carefully placed to promote constant airflow, helping to regulate temperature and keep the rider cool under pressure.
Designed with a balance of innovation and practicality, the SM5 Helmet is more than just safety gear—it’s a performance-driven tool that enhances the riding experience. With its lightweight shell, advanced impact liner, and rider-centric comfort features, the SM5 stands out as a reliable choice for motocross enthusiasts seeking top-tier protection and comfort in a single, thoughtfully engineered helmet.
