Missed the clear comment. My bad... I posted this originally.
These are the best "thin" cases I've seen.
First:
The elago slimfit. These have the best feel I've seen. Not too slick. Not rubbery at all. The edges aren't sharp corners but rather rounded and it has a fantastic feel in your hand.
Second:
The Desmay slight. .35 mm thin. That's crazy! Most thin cases are around .8 mm. This is less than half the bulk of most thin cases. Scratch protection only. This is offered in a transparent grey.
