Designed and shaped specifically for Kids and younger riders, the all-new SM3 Youth is designed for MX, Enduro, and all Off-road use. It features a range of technologies and innovations taken from Alpinestars’ range of adult helmets to deliver the optimal blend of performance, protection, and comfort.
FEATURES
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 lightweight.
The 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 a YM size to initially buy a 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 who 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.
Alpinestar’s 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 defence against oblique impacts.
A patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the force on the rider’s neck during an impact.
The 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.
Maximized ventilation and high levels of heat transfer exchange thanks to 10 inlets and seven exhaust ports.
The visor has been designed to direct air into the ports for enhanced airflow.
SAFETY
Alpinestars has introduced a new in-house standard for the SM3 Youth to test the helmet’s chin to conditions heavier than the homologation standard, and in order to pass Alpinest
