Most waterproof cases turn your iPhone 5 into a mammoth of a phone. Lifeproof on the other hand can give your iPhone a decent amount of protection while keeping it slim. Like the previous versions, the Lifeproof case for the iPhone 5 is waterproof, shockproof, dirtproof, and snowproof. It's also lighter, tougher, and sound better thanks to the “completely re-engineered speaker ports” that “delivers maximum acoustic output and sound clarity”. The demand is so great it seems like Lifeproof is having a hard time keeping up.
The iPhone is outdated and the case for it is no longer available except for the latest iPhones at Lifeproof.com
