The Alpinestars SM3 Helmet in Heat Gloss Red/White/Black offers advanced protection and comfort designed specifically for motocross, enduro, and off-road riders. Its shell construction features varied thicknesses of impact-resistant thermoplastic, which optimize impact absorption while maintaining a lightweight profile. The thermo-injected shell incorporates a unique polymer blend engineered for durability and performance, ensuring that riders are well-protected during demanding rides. Inside, a six-piece EPS liner with five density zones manages impact energy effectively, reducing the risk of injury. The polished inner liner with a special coating minimizes friction, aiding rotational impact management and contributing to rider safety. Additionally, the helmet's design includes a low friction coating on the inner EPS surface to reduce rotational acceleration forces that can occur during oblique impacts. The helmet's ventilation system is highly efficient, featuring ten intake ports and seven exhaust outlets that promote maximum airflow and heat transfer, keeping riders cool and comfortable even during intense activity. The visor is designed to channel airflow into the vents, enhancing overall ventilation, while its release system ensures safety by releasing with a pre-determined force, reducing strain on the rider’s neck during a crash. Comfort is further enhanced with a liner crafted from recycled materials, supporting sustainability without sacrificing performance. Integrated hydration tube channels in the cheek pads add convenience for riders during long sessions. The chin strap is a 25mm textile strap, providing a secure and comfortable fit. Safety features include an Emergency Release System and removable cheek pads for easy and safe removal, even while the helmet is worn. The 3D contoured foam padding ensures a snug, comfortable fit, while the chin area is optimized for superior impact performance. Stainless steel D-rings guarantee a secure fastening, completing a helmet that balances protection, lightweight design, and rider comfort for off-road adventures.
