Alpinestars Supertech S-M10 Alloy Helmet

Features:

  • A-Head: Patented system allows easy adjustment of the angle that the helmet sits on your head. MIPS system is also included in the helmet.
  • Visor: Patented system has been developed to provide the right level of resistance to release when needed with impacts from any direction. The visor system is light weight.
  • Collarbone: The bottom side of the helmet is raised to clear the collarbone as much as possible for riders who choose not to wear a neck brace system. In addition, the bottom trim is soft on the collarbone area.
  • Mouthpiece: To maintain strength of the mouthpiece, a radial ridge has been incorporated which assures complete strength to the front of the helmet.
  • Maximum Ventilation: The Interior air network channeling has extremely high ventilation values made possible by the airflow design and the location of all air intakes and outlets
  • Four Individual Shell Sizes: XS/S, M, L, XL/2XL
  • DOT/ECE Rated
