Power and protection. Two of your main concerns when dragging an iPhone into the wilderness. The Mophie Juice Pack H2PRO Case covers both. It gives you a 2,750mAh battery — enough for a complete recharge of an iPhone 6 — integrated into a case that offers IP68 waterproof protection and exceeds military standards for vibrations, shocks, and drops. It won't make LTE magically appear in the woods, and it won't help save you from a bear attack or start a fire, but as rugged multi-function cases go, it's as good as you're going to get.
