Ultra Thin cases for iPhone 5?

Try Incipio. Not sure about clear cases, but they have translucent.

Edit: actually, don't see any of their translucent cases rolled up for iP5 yet.

Looks like Incase has thin translucent cases for iP5.

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.

Third:
The SGP Thin Air
Very professional. Hard corners. I like the look. But it is third on my list of thin cases. This is offered in clear.
