Lifeproof cases: the new innovation in cell-phone protection. At Lifeproof, we understand that life happens… and unfortunately our phones can’t withstand all of it. That’s why we made a phonecase that could. Lifeproof cases are waterproof, dirt proof, shock proof and snow proof; so no matter where you are, or what you’re doing, you can be sure that your phone will be Lifeproof.
