Hi guys, I've always been a loyal Otterbox user and currently have the Defender case on my 4S. But it has torn at the mute switch and I am considering a new case. Any guidance would be great. I work in construction so the phone needs to well protected and a screen cover is a must, but it would be great if I could get a protective case that was not as bulky as the Defender Series. Is Lifeproof a slimmer case?
