There's few options, I know spigen makes a good one. Are you planning to go naked with only a wrap? Or planning to put on a shell? If you plan to go naked but just want scratch protection I recommend go with **********. If you are planning to still use a shell, then you will need something thin like spigens protection
If you want static cling, you won't be able to find one that covers the sides and corners. You can get a colored or textured skin that's dry install and has full coverage from places like sticker boy, decalgirl, etc. I don't think there are any clear dry installs that cover the entire back.
Check out Bodyguardz. They have a clear back skin that applies dry. I can't specifically speak about this skin but I have their carbon fiber type skin and have used other Bodyguardz products and both their products and customer service are top notch.
And with the Bodyguardz you can purchase just the back skin.
