Edge only case for S7 Active?

[zr2s10]

Has anyone come across a case that only goes around the edge of the phone, and leaves the back exposed? Preferably something with port covers. I'd like to leave the back exposed (clear backs just trap dirt, in my experience), and make the buttons a little less PPP (pocket press prone). I used to always call them "bumper cases", but apparently everyone on Amazon has started using that term for pretty much EVERY case on the market. :-
