Can anyone recommend a good pair of sunglasses in the under $50 range? I'm looking at the Coyotes and Optic Nerves from Nashbar. Anyone have experience with these products? I've used Uvex for years. I like the idea that if a piece of gravel came at you at 60mph your would be covered. Unfortunately, the frames on the glasses do not hold up. I've been through several pair of these over the years and they always break at the ear piece right where I hook my Take-A-Look mirror.
