iSkin's new Exo for iPhone 5c ($30) is a different take on the rubber cases we're used to seeing. It's molded with a rugged design, including thick ridges along the back that help absorb shock and prevent damage. The high level of protection extends to the Sleep/Wake and volume buttons, which are covered, and the Lightning port, with its flip-open cover. Exo comes in solid black and translucent white.
