Liz reviews the Outdoor Tech SAFE 5 iPhone Waterproof case. The name Outdoor Tech is enough to make people think about tech products made for the great outdoors, so when it comes to cases and whatnot, it doesn’t surprise is that the Outdoor Tech Safe 5 case for the iPhone 5 is waterproof. Taking a dip in water shouldn’t be an issue with this one, as its IPX-7 rating ensures that it’ll be safely protected when it’s submerged in up to 3 feet of water for 30 minutes.
