Want a cover for my iPhone 5. Anybody know where to find one?

Let me just be clear: I'm NOT looking for any type of smart cover idea, just something that attaches to maybe half of the back of your iPhone and covers the screen. Something like the S3 cover. Doesn't have to be the same, but does anybody know of something similar? Keep in mind, I know about the Surfacepad from Twelvesouth, I don't like that because it doesn't allow for easy one handed access.
