A very comfortable photochromic goggle that deals with the problems of steaming up when climbing by having a 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 Photochromic "Reactiv" lens (adjusts from cat 2 to cat 4 - Visible Light Transmission 20% to 5%), for very bright glary conditions and high altitude.
- SuperFlow System enables the screen to edge forward for greater ventilation, while remaining perfectly protected from the sun's rays.
- Automatic adjustment from Category 2 to Category 4.
- Polarised to reduce glare.
- Spherical screen and minimalist frame for a huge field of vision.
- Sized to fit medium to large heads.
Really good goggles for mountaineering in the greater ranges.
