A very comfortable light-reactive goggle that deals with the problems of steaming up when climbing by having a very clever lens that can be clicked forward with gloved hands to allow air in all round the edge of the lens and then clicked back into place for the descent - all without taking it off your head.

This version has a reactive lens (adjusts from cat 1 to cat 3 - Visible Light Transmission 75% to 17%), for poor weather and overcast conditions as well as sunny skies. The red lens tint accentuates terrain relief.

  • SuperFlow System enables the screen to edge forward for greater ventilation, while remaining perfectly protected from the sun's rays. 
  • Automatic adjustment from Category 1 to Category 3.
  • Spherical screen and minimalist frame for a huge field of vision.
  • Sized to fit medium to large heads.

Really good goggles for Scottish winter mountaineering and northern latitudes ski touring.
