I've owned these glasses for over a year now, almost two. I wear them almost daily and have put them through their trials without a doubt. They've survived backpacks, pockets, cars, bikes, friends, etc. I love them. They fit my face perfectly (my head is a bit on the larger side) and they are comfy. The nosepads fell off less than a couple weeks after purchasing them since they're not secured on at all, but I've been wearing them ever since without nosepads and haven't any problems.
I love the cam action of the hinges; I can put them on the front of my shirt collar and they stay folded. And when I pick them up, I can one hand flip them completely open so I can slide them right over my baby blues and conquer the next adventure.
The smoke polarized lenses are beautiful. I'll wear them in bright sunlit snow all day with zero eye problems, but I'll continue to wear them while on a bike ride into late evening. The polarization makes it so glare is extremely reduced, but the whole world isn't dark. I wear them when I'm sailing and all the sun glare on the water disappears while I can actually see into the water through the sun glare. Amazing.
One more thing: the frame is stiff enough (full thick plastic) that they curve to my head and stay on, but they aren't pressing into the sides of my head a lot. It's a good design.
Alright, done singing praises. Obviously, these aren't going to work with someone with a tiny face, and they aren't the most styling things for wearing regular everyday, but if you're looking for some sport glasses for sailing, hiking, biking, snow sports, etc...you found them.
I included a picture of me near base camp on Mt. Shasta wearing my favorite glasses and a burger king hat.
