The Alpinestars SM3 Helmet in Heat Gloss Red/White/Black, size 2XL, offers exceptional protection designed specifically for motocross, enduro, and offroad riders. Its varied thickness shell construction incorporates a thermo-injected polymer blend, engineered to optimize impact absorption while maintaining a lightweight profile. The impact-resistant outer shell is made from durable thermoplastic, providing reliable defense against impacts, while the inner shell features a composite fiber layer sandwiched between the outer shell and EPS liner for enhanced impact resistance. This construction ensures that riders receive superior protection without sacrificing comfort or agility. The helmet's fit can be precisely tailored to individual head shapes thanks to adjustable crown and cheek pads, offering a snug and comfortable fit for extended riding sessions. The internal padding employs a multiple-density liner system with five different densities across the six-piece EPS liner, managing impact forces effectively and reducing overall helmet weight. Additionally, the polished EPS liner features a special friction-reducing coating that works in tandem with the comfort liner to mitigate rotational impacts and oblique impact forces. Ventilation is a key feature of the SM3 helmet, with ten inlet vents and seven exhaust ports designed to maximize airflow, keeping riders cool during intense activity. The visor has a dedicated airflow channel and a release system that ensures a safe, controlled detachment during impacts, helping to reduce neck strain. Eco-conscious riders will appreciate the use of recycled materials in the comfort liner, emphasizing sustainability without compromising performance. Integrated hydration tube channels in the cheek pads allow for quick and easy hydration during rides. Safety features include an emergency release system with removable cheek pads that facilitate safe removal without helmet displacement, and the chin area is optimized for superior impact performance. Stainless steel D-rings provide a secure fit, ensuring the helmet stays firmly in place. Overall, the Alpinestars SM3 Helmet combines advanced construction, innovative impact protection, and rider-focused comfort features, making it an ideal choice for offroad enthusiasts seeking reliable, lightweight headgear that performs under demanding conditions.
