The Alpinestars SM3 Youth Solid Helmet in Black Matte is expertly designed for young riders engaged in motocross, enduro, and off-road activities. This helmet combines advanced safety features with a comfortable, lightweight design to ensure optimal protection and performance for children and younger riders. Its thermo-injected shell, made from impact-resistant thermoplastic, offers a durable barrier against impacts while maintaining a lightweight profile, weighing approximately 23.4 ounces. The shell's engineered thickness varies to enhance impact absorption without adding unnecessary weight, providing a balanced blend of protection and comfort.
Designed with versatility in mind, the SM3 Youth features a modular interior that allows for tailoring the fit through interchangeable crown and cheek pads, ensuring a secure and comfortable fit as the rider grows. The helmet is available in three sizes, with the Youth Medium sharing the same EPS liner size as the Youth Large to facilitate size adjustments over time. The inner liner incorporates multiple densities to optimize impact absorption, while the inner and outer surfaces are engineered to reduce the effects of oblique impacts. A patented low friction coating on the EPS liner mimics the body's natural cerebrospinal fluid, reducing rotational forces during certain impacts, which is critical for protecting the rider's brain.
The helmet includes a safety-enhancing visor release system that minimizes neck forces during impacts, and a removable cheek pad system for easy maintenance and customization. The interior features a comfort liner made from recycled materials, reflecting Alpinestars’ commitment to sustainability. Hydration tube channels integrated into the cheek pads provide convenience during rides, maintaining hydration without compromising safety or comfort. The SM3 Youth meets both DOT and ECE 2206 standards, making it suitable for use worldwide. Its maximum ventilation is achieved through 10 intake ports and seven exhaust outlets, with the visor designed to channel air efficiently into these ports for superior airflow and heat transfer, keeping young riders cool during intense activity.
Constructed with safety as a priority, the helmet features an emergency release system, stainless steel D-rings for secure fitment, and a soft textile chin strap for added comfort. The shell thickness and structure have been optimized in critical impact zones, especially the chin area, to pass rigorous in-house testing standards. The helmet’s visor has a patented release mechanism that ensures safety during impacts, effectively reducing neck strain. Overall, the Alpinestars SM3 Youth Solid Helmet offers a comprehensive package of safety, comfort, and innovation tailored specifically for young off-road enthusiasts.
