Toughest case for iPhone 4S?

Look, it needs to be TOUGH. And I have the otter box defender but otterboxes look to wimpy to me. I've seen some cases that look like they have screws in them and they're more metal looking. I kinda want something like that
So yeah it needs to be tough and not an otterbox or similar looking.
I'm alright if it's bulky and it would be nice if its waterproof and camo but not an necessity. Just something to walk around in the swamps in and not be afraid to take a beating.

Your not going to find anything tougher than the defender series. I searched all over for weeks, until I was at work and dropped my Iphone off a ladder 2 stories in the air onto concrete, and it didn't have a scratch on it (the rubber was bruised however but from 2 stories what do you expect). After that incident I'm glad to say that the defender series lives up to its name. Rumor has it that you can run it over with a car, and it wouldnt damage the phone. (that i don't know for sure and I wouldnt want to be the one to test it lol)

LifeProof; it's waterproof, dirt-proof, snow-proof, and it sounds perfect for you, but it doesn't come in camo, sorry.
