Firstly, I bought these for the lenses, and for the price, this is a great deal. The lenses work great on bright days, I haven't gotten them to the mountain yet, but I plan to in a month and a half, so I'll update if I can remember, lol!

The leather bits are a little awkward at first, but after a while you don't even notice them. My one and only complaint is that the wrap around ear pieces tend to cause me some ear pain after wearing them for an hour or so. I imaging this will get better with time though.
