Ray-Ban is an iconic brand & one that needs no introduction. The Cats 5000 model is a slightly re-worked version of the classic Aviator style & one that's a little more robust. Made from a propionate plastic for durability they are streamlined & lightweight but far from flimsy. As usual, the timeless branding decorates one of the arms & the whole affair is rounded off nicely by a leather case for optimized protection.
