SM3 Helmet - Radium - Gloss Black/Red Fluo/White - Small

The Alpinestars SM3 Helmet in Radium color offers a high-performance design tailored for motocross, enduro, and off-road riders. Crafted with a varied thickness shell construction, it provides an optimal blend of impact protection and lightweight comfort, ensuring you can ride longer and safer. The thermo-injected shell combines impact-resistant thermoplastic with a polymer blend, engineered to absorb shocks effectively while maintaining a low weight for enhanced maneuverability.
Inside, the helmet features a multi-density EPS liner with five different densities, strategically positioned to maximize impact absorption and reduce overall weight. The polished inner liner with a special coating minimizes friction, aiding rotational impact management and decreasing the risk of injury during oblique impacts. The helmet*s design also includes a low-friction coating on the inner EPS liner to further reduce rotational acceleration forces, adding an extra layer of safety during crashes.
Ventilation is a key feature of the SM3 helmet, with ten intake ports and seven exhaust outlets that promote superior airflow to keep riders cool during intense riding sessions. The visor is designed to channel air into these ports, enhancing airflow and rider comfort. A visor release system ensures the visor can detach with a pre-determined force, reducing strain on the rider's neck during impact. Comfort is further improved through a liner made from recycled materials, reflecting Alpinestars* commitment to sustainability. Integrated hydration tube channels in the cheek pads provide convenience without sacrificing safety, while a soft, 25mm textile chin strap offers a secure and comfortable fit.
The helmet is equipped with an emergency release system and removable cheek pads that facilitate safe removal while the helmet is still on, essential for quick medical assistance. The 3D contoured foam in the chin area enhances comfort and impact performance, while stainless steel D-rings ensure a tight, secure fit. Designed for optimal fit and safety, the Alpinestars SM3 helmet combines advanced protection features with practical comfort and ventilation, making it an ideal choice for demanding off-road riders.
