Great shades if you don't destroy em...
These are the best shades I've owned. Hands down. Except for the coating on the outside of the lens...polarization coating? I made the mistake of cleaning it with a tissue. and the coating wiped right off, so now it needs to be replaced for 40 bucks. Otherwise, they are great for mountainbiking because they don't fog up and glare is drastically reduced. Enjoy!! and remember- clean them with the supplied cloth only!!!!
