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 Solid Helmet in Black Matte is engineered specifically for young riders, making it an ideal choice for MX, Enduro, and Off-road adventures. This helmet blends innovative technology with a lightweight design to provide optimal performance and protection. Designed with a thermo-injected outer shell made from a unique polymer blend, it ensures impact resistance without compromising on weight. The helmet*s versatility allows for customization as your child grows, with interchangeable crown and cheek pads available as genuine spare parts.

Safety is paramount with the SM3 Youth helmet, which features a patented low friction coating on the EPS liner to mitigate rotational forces during oblique impacts. This helmet also boasts an Emergency Release System for easy removal while still being worn. With optimized ventilation through ten inlets and seven exhaust ports, this helmet keeps young riders cool and comfortable while they ride. The SM3 Youth helmet is your trusted partner in ensuring safety and enjoyment for the next generation of riders.
