Awesome sunglasses - Ray-Ban Top Bar Sunglasses RB3183

This design of sunglasses make them the toughest polarized Ray-Bans I've ever bought. They lenses don't pop out as they are bolted, without a bottom frame on the lenses. 1 pair survived 2 years in Afghanistan. This is not my first purchase of these sunglasses, you might want to buy a couple pairs just in case they stop making them, they are that good.
Pros: tough
Cons: a little expensive, but you pay for quality
