Anatomically engineered and profiled specifically for youth and younger riders, the all-new SM3 Youth Helmet 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. The SM3 Youth weighs 1060 g (ECE)
  • 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 spare parts in different thicknesses.
  • Youth Medium (YM) and Youth Large (YL) 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 (YS) 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.

  • ALPINESTARS NEW SAFETY STANDARD 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 the Alpinestars’ new standards, the shell thickness and the structure of the helmet design itself have both been optimized in the chin area for superior impact performance.
  • Equipped with an Emergency Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort.
  • Stainless steel D-rings ensure a tight and secure fit.
  • The SM3 helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide.
