Description

The Alpinestars SM3 Radium Helmet is meticulously crafted to deliver an optimal blend of performance, protection, and comfort for serious off-road riders. Its thermo-injected shell features a varied thickness construction, utilizing a polymer blend that is engineered to provide an ideal balance of impact resistance and a lightweight feel. This advanced design, combined with an inner shell constructed from composite fiber, offers maximum protection against high-energy impacts. For enhanced safety against rotational forces, the helmet incorporates a 6-piece EPS liner with five distinct densities, strategically placed for superior impact absorption and effective management of oblique impacts. A special low-friction coating on the inner EPS liner further reduces rotational acceleration forces, safeguarding your head during certain angled impacts. Rider comfort is paramount, with maximized ventilation achieved through ten intake ports and seven exhaust ports, ensuring high levels of heat transfer and airflow. The visor is cleverly designed to direct air into these ports, further boosting ventilation. The Alpinestars SM3 Radium Helmet also includes an Emergency Release System (ERS) with removable cheek pads for safe helmet removal, a 25mm soft textile chin strap, and durable stainless steel D-rings for a secure fit, making it an essential piece of lightweight motorcycle helmet gear for any adventure.
