The orange LifeJacket for LifeProof iPhone 4/4S Case from LifeProof is a foam flotation device that will prevent your iPhone from sinking. When installed in your iPhone's optional hard shell case, the high-buoyancy foam casing not only keeps the phone afloat but will add shock protection in case you drop it. The material also provides a firm grip. Since it floats, it's easy to spot in the water. While installed, you'll still maintain access to your iPhone's features. The LifeJacket comes with a quick-release lanyard as well as a hand strap.
