Julbo Dirt Sunglasses - Zebra Antifog Lens

They stay put on your head with the rubberized temples and nose pieces...lenses change with the brightness, and they are close fitting...but they still are a little light for long periods of time on the glacier, and if you where a hat, the lenses are shaded and tend not to darken as much. Folks are 50/50 on whether I am cool enough to rock white frames, but I like them! One day of doing some chainsaw/glading work with them though pretty much wrecked the lens coating, so I don't know if that is unique to chainsawing kickback or if a muddy mountain bike ride might do the same thing. Either way, I have been happy with them!

I just used these on a summit of Mt Adams this weekend. It was in the mid 80's and almost not a cloud in the sky. I could not believe how well they worked from 6am in the morning until 6pm in the evening. These didn't leave my face. Even with full intensity, the photochromatic lenses adjusted spectacularly and I could face the glacier all day. In the morning anyone can see my eyes. By the time we hit the glacier, all you could see was this metallic golden shield (kind of like the visor in Halo!). They never slipped. They never fogged up - even in full intensity work-out up the glacier. When I returned to camp they were dirty from sunscreen and who knows what else, but I could even tell. Normally on sunglasses, I notice every spec. These are definitely the best performing sunglasses I've ever owned. One other note - you don't want polarized lenses for glaciers - you can't tell the difference between snow and ice. Also, my guide company for Mt Rainier recommends these for glacier glasses (so even though Julbo doesn't market these for such purposes, they work extremely well for it).
