Designed specifically for young motocross, enduro, and off-road enthusiasts, the Alpinestars SM3 Youth Radium Helmet combines advanced safety features with tailored comfort for growing riders. This helmet features a lightweight thermo-injected shell crafted from impact-resistant thermoplastic, incorporating varying thicknesses to optimize impact protection while minimizing weight. With a total weight of approximately 37 ounces, it offers a comfortable fit without sacrificing safety, making it ideal for children and young riders engaged in high-impact activities. The helmet is available in three sizes—Youth Small, Youth Medium, and Youth Large—with separate shells for DOT and ECE certifications, ensuring compliance with international safety standards. The DOT version includes a composite fiber layer between the outer shell and EPS liner to enhance impact absorption, providing peace of mind for parents and riders alike. The adjustable fit is achieved through interchangeable crown and cheek pads, which accommodate growing heads and can be customized for optimal comfort and security. The Youth Small size is designed for children aged 3 to 4 years, with a dedicated EPS size for a more precise fit, while the Youth Medium and Large sizes share the same EPS, allowing for easy size transition as the rider grows. The helmet features multiple density inner liners that absorb impact effectively and reduce overall weight, while engineered surfaces help mitigate oblique impact forces. An innovative low-friction coating on the EPS liner mimics cerebrospinal fluid, reducing rotational forces during oblique impacts for improved brain protection. The visor release system is engineered to detach with a pre-set force, decreasing neck strain during impacts. Comfort is further enhanced through a recycled-material inner liner and integrated hydration channels within the cheek pads, supporting active riders. Ventilation is maximized with ten air inlets and seven exhaust ports, complemented by airflow-directed visor design that channels air into the ports, ensuring optimal heat dissipation during intense activity. The helmet is equipped with an emergency release system and removable cheek pads for safe handling and cleaning, while the 25mm textile chin strap and stainless steel D-rings ensure a secure, comfortable fit. Conforming to both DOT and ECE 2206 standards, the Alpinestars SM3 Youth Radium Helmet offers reliable, high-performance protection tailored for young riders seeking durability, safety, and comfort on the track or trail.
