6D ATR-1 Super Cool Helmet Liner

Replacement liner for the 6D ATR-1 Helmets. The 6D Super Cool Liner is a unique perforated outer fabric combined with an exclusive open-cell 6D mesh material that completely replaces the dense foam. The result is a dramatic increase in air flow. Moisture quickly evaporates, and air can travel through with little restriction, allowing cool air in and heat to escape. When combined with the 6D Air-Gap Technology in the helmet, the performance is unequaled.

The MS size liner falls inbetween the small and medium OEM liner, allowing you to create a custom fit.


  • It's a real luxury to have an extra liner to switch out between motos
  • Proprietary design provides optimum support, comfort and fit
  • Features genuine CoolMax anti-bacterial fabric for a superior sweat management solution
  • Snaps in-and-out in seconds for fast and easy attachment and removal
  • Completely machine washable
