Toughest/Slimmest iphone case?

I currently have an otterbox commuter i think? I just took it off and rediscovered how slim my iphone 4s was, i need a case thats slim as possible but will prevent a 3' fall since i usually don't drop it and break its fall on something but i don't want the screen to crack or get scratches on either side. So i know everybody is looking for this answer but if anybody has any suggestions that would be appreciated. Also i want one piece none of those two part cases and it doesn't have to cover the power or headphone jack

I don't like bulky case either. And I got a slim case for my iphone 4s. And I think that Kate Spade cases are slim, fashionable and protecive. Share with you some of them, and sincerely hope that you can find what you need.

Best case mall is good choice~
