Light retro frames
Many people pick up a pair of frogs and automatically comment that they feel cheap. This comment seems to be due to how light these are. Since the Frogskin is more slim lined than a pair of Rayban Wayfarers, it is lighter. This is a good thing though. It feels like you have nothing on your face. Couple this with high end Oakley optics, and you have a super light, high end pair of shades. Of course these have good style too. Some people have said that these can't be used for active use. I've snowboarded with them plenty of times and never had a problem with them flying off or getting heavy wind drafts, across my eyes. I am sure there are other Oakleys that wrap better, but they probably weigh more than these.
Fit wise, I think these are similar to a size L rayban wayfarer frame. If you have a bigger head, these rule.
