The Alpinestars SM3 Helmet is engineered for offroad enthusiasts seeking optimal protection, lightweight comfort, and superior performance. Featuring a thermo-injected shell with varied thicknesses, this helmet offers enhanced impact resistance while maintaining a lightweight profile, ideal for motocross, enduro, and off-road riding. The impact-resistant thermoplastic outer shell is combined with a composite fiber inner shell, providing maximum impact absorption and structural integrity. A six-piece EPS liner with five density zones ensures the helmet adapts to different impact areas, reducing rotational forces and enhancing rider safety. The polished inner EPS liner, coated to minimize friction, works in tandem with the comfort liner for effective rotational impact management and increased comfort during extended rides. Ventilation is a key feature, with ten inlet vents and seven exhaust ports designed for high airflow, keeping the rider cool and reducing heat buildup. The visor is engineered to direct airflow into the ventilation ports, further enhancing cooling. A visor release system allows quick removal with a pre-determined force to protect the rider's neck during impacts, while the helmet's fit can be tailored with adjustable crown and cheek pads for a secure, personalized fit. The interior features a comfort liner made from recycled materials, supporting sustainability efforts. Integrated hydration tube channels in the cheek pads and a soft textile chin strap provide additional convenience and comfort. Safety is prioritized with an Emergency Release System, removable cheek pads, and a 3D contoured foam liner that ensures a snug, comfortable fit. The chin area is optimized for impact performance, and stainless steel D-rings secure the helmet firmly in place. Designed for demanding off-road conditions, the Alpinestars SM3 Helmet combines advanced construction, innovative safety features, and rider comfort to deliver a high-performance helmet suitable for motocross, enduro, and off-road adventures.
