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.
Engineered for the next generation of riders, the Alpinestars SM3 Youth Radium Helmet is designed specifically for youth motocross, enduro, and off-road adventures. This helmet combines advanced safety features with a lightweight design, ensuring young riders stay protected without compromising on comfort. Built from a durable thermo-injected shell using a special polymer blend, it offers a great balance between impact protection and ease of wear. Weighing in at approximately 1060g for ECE certification, the SM3 Youth is perfect for young enthusiasts gearing up for their next ride.
The SM3 Youth incorporates multiple cutting-edge technologies, including a patented low friction coating on the inner EPS liner to minimize rotational forces during impacts. The helmet features adjustable crown and cheek pads, allowing for a customized fit as your child grows. Additional features include a ventilation system with ten inlets and seven exhaust ports for optimal airflow, ensuring a comfortable riding experience. With the Alpinestars SM3, your young rider can enjoy their adventures with confidence and style.
