The design is great and the glasses are super light and comfortable. I have Oakley's, Ray Ban's, Costa's, and many more and for some reason I always go back to my Shakas because you don't even realize your wearing sunglasses. I do wish the packaging, case and cleaning bag, etc. were better quality. I only received a flimsy ripstop bag to hold them that couldn't even be used to clean the lense. Additionally The lenses my glasses came with and the alternat lenses I purchase both came in a plastic bag and both lenses were scratched. The quality control and lense quality needs to be better. I've had Rudy Project sunglasses and the spare lenses cam in a nice microfiber pouch.
