Some of us use our iphone for everything. In the field you probably reach for it to grab photos of events and even shoot movies on the fly. This iphone case will give you even more capacity with your phone at camp. Shooting the blob or the belly flop contest could be even more sweet with some underwater footage. The TAT7 can withstand pressure of up to 100 ft. below surface. It’s kind of pricey at $85 but then again I’ve never mass produced an iphone case.
