I had always been a fan of RSF. This pair came with lenses that are flatter than usual for a modern look. Very nice hinge and the Asian size I got was a great fit for my wider temples. Only feedback I have is for the silver lettering on the inside, where they woul come off easily under sweat/oil (in fact, half of the letterings came off).
I was not too sure at first because they are not polarized, but as soon as I put them on, I was sold!
I will definitely be looking to add to my collection with other models!
