Hey guys, I am continuing on my search for a dustproof case for my iphone 5. I have tried lifeproof fre (can't stand the oil canning and wavy screen) and the incipio atlas (screen and sound issues). After trying both of these, I went with just a regular case and screen protector but I am in dusty environments quite often and the dust just drives me crazy. I am considering trying an otterbox armor but I am a little concerned about the bulk but can possibly get over it. Any other dustproof options out there? The atlas would be the perfect case if not for the screen and sound issues. I really liked the thought of a glass screen protector. Any help would be greatly appreciated.
