I won't go into much detail about the various highlights of these shades, there are too many.  These are really great sunglasses in almost every way you could ever want, my one and only qualm is that they don't grip very well on the nose and have a tendency to slide a lot if you're sweating in the least bit.  And since they are SUN glasses they are usually on my face in a situation where SWEAT might occur (heaven forbid!).  I love the clarity and the design, these are truly fabulous shades, I just wish Ray Ban could design them to have a little more traction on the bridge grips.
