Alpinestars Youth SM3 Fray Helmet

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.

Shell:

  • Thermo-injected shell
  • 3 shell sizes
  • SM3 Youth weighs 1060g (ECE) and 1170g (DOT)
  • Fit can be tailored to the rider’s head replacement liner and cheekpads
  • 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

Comfort:

  • Youth Medium (YM) and Youth Large (YL) sizes share the same EPS size
  • The Youth Small (YS) has a smaller EPS size and can be customized only via the cheek pads
  • Youth Small sizes 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
  • 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
  • 10 inlets and seven exhaust ports
  • 25mm soft textile chin strap

Safety:

  • Stainless steel D-rings
  • Emergency Release System and removable cheek pads
  • DOT and ECE 22.06 certified
