Alpinestars Youth SM3 Helmet

Designed specifically for young and smaller riders, the SM3 Youth Helmet excels in MX, Enduro, and Off-road settings. Incorporating advanced technologies and design elements from Alpinestars' adult helmet range, this helmet offers an exceptional combination of performance, protection, and comfort, making it an ideal choice for younger enthusiasts seeking professional-grade gear.

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

Features:

  • Visor directs air into ports
  • Patented visor release system
  • Integrated hydration tube channels in cheek pads
