What's a good iphone case thats not big and bulky?

I have an otterbox and it is way too big and bulky. What's a good smooth iphone case
Thats not big and bulky but will easly slide in and out of your pocket. And the protection is near the protection of an otterbox. I have a 4s

What oterbox do you have the defender or the commuter? The commuter isn't very bulky in my opinion and you can't beat the oterbox protection

I think metal case is most protective and cool which not make your iphone look too bulky
