Julbo photochromatic sun glasse - Julbo Bivouak Mountain Sun Glasses

I was having a difficult time finding a pair of sun glasses that would not fog up while cross country skiing. I also needed different types depending on cloudy or sunny conditions. I figured if they used these on Everest they would probably work well in Minnesota. They are the bomb! They automatically lighten and darken depending on conditions and they have never ever fogged. I loved them so much I bought my wife a pair as well.
Pros: Top of the line cross country skiing sun glasses
