The Alpinestars SM7 Blaster helmet is engineered for off-road racing and demanding powersports use, combining a lightweight composite shell with advanced impact protection, ventilation, comfort, and aerodynamic performance. Its multi-layer shell blends fiberglass, carbon, and aramid fiber to help manage impact forces, promote energy dissipation, and support durability during high-performance riding. The streamlined shell profile is free of unnecessary external channels that could create load points, while its curved shape encourages deflection and reduced friction during an impact. This Alpinestars helmet is finished in Black/Gray/White/Yellow Fluo and is offered in size XL.
The SM7 uses 20 individual ventilation ports, including 13 intake ports and 7 exhaust ports, to help maintain airflow during intense off-road riding. Removable, washable liners feature antimicrobial fabric treatments, while the adjustable top pad and interchangeable cheek pads allow riders to refine the fit. The A-Head Fitment system provides additional adjustment at the crown, and Alpinestars replacement cheek pads can be exchanged across shell sizes. Integrated channels support hydration tube installation, and the cheek pads include an emergency extraction system along with speaker recesses for compatible communication systems. The helmet also includes a 25 mm nylon chin strap with stainless steel double-D rings and removable covers for convenient cleaning.
Protection-focused features include the Alpinestars Visor Detaching System, which is designed to release the visor from the shell when subjected to impact energy greater than 15 Joules, helping reduce potentially harmful forces regardless of impact direction. PLASMA technology is integrated into the lower side pads to support shock absorption near the collarbone area, while the crown and neck pads are elastically connected to assist with oblique impact management. The Alpinestars SM7 is a suitable fit for off-road racers and riders seeking a ventilated, communication-ready helmet with customizable comfort and advanced shell protection.
