Otterbox Defender is practically indestrictable. I wouldn't drive over it, but I did have one phone flung, screen-first, to a wall about 8 feet away. I was sure the phone was gone and he sheetrock was cracked - but nothing happened. The phone fell down to the floor and it was still working. (That was about 4 years ago - and it's still working. In the Defender case.)
And since I prefer carrying my phone on my hip, the Defender is the perfect case for that too - you'd have a hard time breaking the holster.
It's a bit expensive, but so is the phone.
