For something a little more heavy-duty, consider the new BioLogic Hard Case for iPhone 5: Combining a simplistic look, extreme durability and a flawless touch screen experience,this is the ultimate line of defense for your iPhone. Built of precision-machined, aerospace-grade aluminum, secured by seven screw (tool and extra screws included) the Hard Case for iPhone 5 is an extremely durable and waterproof case (tested to IP68) that is also very thin and light - weighing in at only 86 grams. Unlike many of its kind, the Hard Case uses a waterproof, adhesive screen cover that gives the same touch and feel of a naked phone.
