The Alpinestars SM3 Helmet is designed for motocross, enduro, and off-road enthusiasts seeking optimal protection and comfort. Its shell construction features varied thickness layers that combine impact resistance with lightweight performance, ensuring riders are protected without unnecessary bulk. The thermo-injected outer shell is crafted from impact-resistant thermoplastic, while the inner shell uses a composite fiber material positioned between the outer shell and EPS liner for enhanced impact absorption. This layered design delivers a balanced blend of durability and weight savings for demanding off-road conditions.
The helmet's fit can be precisely adjusted with customizable crown and cheek pads, allowing riders to achieve a snug, secure fit that minimizes movement during rides. Multiple density inner liners, including a six-piece EPS liner with five different densities, ensure targeted impact management, reducing energy transfer and improving safety. The polished EPS liner features a special coating that reduces friction and rotational impacts, protecting the rider from oblique impacts that could cause rotational injuries.
Ventilation is a key feature, with ten intake ports and seven exhaust vents working together to maximize airflow and heat exchange. The visor design channels air into these ports, enhancing cooling and comfort during intense rides. An innovative visor release system ensures the visor detaches with a controlled force, helping to reduce neck strain during impacts. The interior comfort liner uses recycled materials to lower the helmet's carbon footprint, and integrated channels in the cheek pads facilitate hydration tube placement for added convenience. The soft textile chin strap provides a secure fit, while a stainless steel D-ring closure guarantees durability and safety.
Safety features include an emergency release system with removable cheek pads for easy and safe helmet removal, even when the helmet is still on the rider's head. The 3D contoured foam offers additional comfort and impact protection, especially around the chin area, which is optimized for superior impact performance. The helmet's design also incorporates a low-friction coating on the inner EPS liner to minimize rotational forces during oblique impacts, further enhancing rider safety. Overall, the Alpinestars SM3 Helmet combines advanced materials, innovative design, and safety features to meet the demands of off-road riders seeking high performance and protection.
