Its sturdy, protective, bright orange casing is bouyant, so it will float on top of the water. That means if you accidentally drop your iPhone overboard, you can grab a boat hook and scoop it back up by the lanyard, or use a net to bring it in. And when you finally fish it back onboard, it will work work just fine.
The LifeJacket is easy to install and remove and comes with a lanyard and a wrist strap. It will float in salt or fresh water and costs $39.99.
LifeProof is also launching new colors for its iPhone 4/4S cases, adding teal, blue and red to the line-up later this summer.
