The Alpinestars SM5 Action 2 Helmet offers advanced protection with a lightweight impact-resistant thermoplastic outer shell designed for durability and safety. Its aerodynamic design enhances airflow through strategically positioned vents, ensuring optimal ventilation during high-performance riding. Integrated hydration tube channels within the cheek pads provide convenience for riders who need quick access to fluids without removing their helmet, promoting hydration during extended rides. The helmet's inner and outer surfaces are engineered to minimize damage from oblique impacts, enhancing rider safety in a variety of crash scenarios.
Side shell construction combined with soft EPS foam layers helps prevent collarbone injuries by absorbing and distributing impact energy effectively. The soft 26mm textile chin strap exceeds certification requirements, providing a secure and comfortable fit that accommodates long rides. Multiple density inner liner layers are precisely positioned to maximize impact absorption, offering tailored protection in critical areas. The helmet features an emergency release system and removable cheek pads, allowing for quick and safe removal without compromising rider comfort, thanks to the 3D contoured foam padding.
A patented visor release system ensures the visor detaches with a pre-determined force, maintaining safety regardless of impact angle. The removable comfort liner is treated with SILVERPLUS® antibacterial fabric, which provides excellent moisture wicking and keeps the helmet fresh and hygienic. The anti-microbial liner is washable, reducing odor and bacteria buildup over time. Stainless steel D-rings guarantee a secure fit, while the overall weight of a size medium helmet is approximately 3 pounds (1370 grams), providing a balance of protection and comfort. Certified both DOT and ECE homologated, the Alpinestars SM5 Action 2 Helmet is suitable for use worldwide, making it an ideal choice for serious riders seeking high-level safety and performance.
