I can't remember if it was here or someplace else, someone asked about using an otterbox. I have an otterbox 3500 for my "survival" kit, and a Pelican 3000 for my first aid box. I really like both of them, and they are a permanant part of the jeep supplies, along with a military shovel/pick combo. The KITS can get beat around and I don't worry about anything tearing up in them. I'm gonna make me a soft sided First aid/fire starting kit sometime withing the next month or so and probably put it with my S5.
