Best all around glasses - Julbo Bivouak Mountain Sun Glasses

I love these Zebra Lenses. I use them year round in the high peaks of Vermont. They stay on my face, and adjust to the changing conditions as I go in and out of the full sun and tree cover. They work really well in low light as well.
I generally have issues with lenses fogging as I go up in elevation, but with these vented lenses I never have a problem. They look and feel great on my face.
