Alpinestars SM3 Helmet - Solid Gloss White XS (Part No. 8300326-2180-XS)

The Alpinestars SM3 helmet is engineered for offroad enthusiasts seeking optimal protection, lightweight comfort, and superior performance. Featuring a thermo-injected shell with varied thickness, this helmet offers enhanced impact absorption while maintaining a low weight, making it ideal for motocross, enduro, and offroad riding. The impact-resistant thermoplastic outer shell is complemented by an inner composite fiber layer strategically assembled between the outer shell and EPS liner, providing maximum protection against impacts and oblique forces. This construction ensures durability and safety during intense riding conditions. The helmet's fit can be customized to the rider's head shape thanks to adjustable crown and cheek pads, offering a secure and comfortable experience for extended use. The six-piece EPS liner incorporates five different densities, effectively managing impact forces and reducing overall weight. A polished inner EPS liner with a special coating minimizes friction, aiding in rotational impact management and enhancing rider safety. The helmet's design incorporates multiple ventilation inlets and exhaust ports, maximizing airflow and heat transfer to keep riders cool during demanding rides. The visor is engineered to direct airflow into these ports, further improving ventilation, while a release system ensures the visor detaches with controlled force to reduce neck strain during impacts. Constructed using recycled materials, the comfort liner emphasizes sustainability without compromising performance. Integrated hydration tube channels and a soft textile chin strap enhance rider convenience and comfort. Safety features include an emergency release system with removable cheek pads for quick removal, a 3D contoured foam for comfort, and stainless steel D-rings for a secure fit. The chin area is optimized for impact performance, providing additional protection where it matters most. Overall, the Alpinestars SM3 helmet delivers a blend of performance, protection, and comfort tailored specifically for offroad riders demanding the best from their gear.
