Anatomically engineered and profiled specifically for youth and younger riders, the all-new SM3 Youth is optimized for MX, Enduro and Off-road use, and features a whole raft of technologies and innovations taken from Alpinestars range of adult helmets to deliver the optimal blend of performance, protection and comfort. This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight. Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three sizes (Youth Small, Youth Medium and Youth Large. The SM3 Youth weighs 1060g (ECE) and 1170g (DOT). Separate versions of the shells for DOT and ECE requirements; the DOT certified version of the helmet’s inner shell is constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts. The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as genuine spare parts in different thicknesses. Youth Medium and Youth Large sizes share the same EPS size, which allows riders with an YM size to initially buy an YM helmet and then configure it to a Youth Large size as they grow via the crown and cheek pad spare parts. The Youth Small has a smaller EPS size and can be customized only via the cheek pads. Alpinestars extensive research has shown that the kids that wear a YS size are very small, typically 3 to 4 years old, and therefore they require a dedicated helmet fit. Multiple density inner liner ensures the helmet is equipped with the correct density in the correct area for enhanced impact absorption, while also helping reduce overall weight. The inner and outer surfaces are engineered to minimize the effects of oblique impacts. Alpinestars patented low friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain’s own low friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts. Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider’s neck during an impact. Comfort liner is constructed using recycled materials for a lower carbon footprint. Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance.
The Alpinestars SM3 Youth Wurx Helmet is specifically designed for young motocross, enduro, and off-road riders, providing a perfect blend of performance, protection, and comfort. Engineered with an anatomically profiled design for youth, this helmet incorporates advanced technologies borrowed from adult models to ensure superior impact absorption and safety. The thermo-injected shell uses a specialized polymer blend with variable thickness, delivering lightweight durability and enhanced impact resistance, making it ideal for active young riders. The helmet is available in multiple sizes, including Youth Small, Medium, and Large, with the capacity for size adjustments through interchangeable crown and cheek pads, allowing for growth without needing a new helmet.Constructed from impact-resistant thermoplastic, the SM3 Youth weighs approximately 37 ounces (1060g) for the ECE version and 41 ounces (1170g) for the DOT certification, ensuring lightweight comfort during extended rides. The inner shell for the DOT version features a composite fiber layer between the outer shell and EPS liner, maximizing impact protection. Multiple density inner liners further enhance impact absorption by providing targeted cushioning, while the inner and outer surfaces are engineered to reduce the effects of oblique impacts. The helmet's design includes a patented low friction coating on the EPS liner, mimicking cerebrospinal fluid to reduce rotational forces during certain impacts, a critical advancement in helmet safety.The visor release system is designed to release with a pre-determined force, helping to minimize neck strain during impacts. Comfort is prioritized with a removable, recycled material-based comfort liner and integrated hydration channels within the cheek pads for convenience. The helmet features a comprehensive ventilation system with 10 air inlets and 7 exhaust ports, directing airflow efficiently for maximum heat transfer and rider comfort. The secure fit is maintained with stainless steel D-rings and a soft textile chin strap, ensuring safety and comfort throughout the ride.Safety features include an Emergency Release System and removable cheek pads for quick and safe removal in emergencies. With homologation conforming to both DOT and ECE 2206 standards, the Alpinestars SM3 Youth helmet is a reliable choice for young off-road enthusiasts seeking optimal protection and comfort on the trail or track.
