Mophie today announced the release of Knox, a premium iPod protector and wallet combo forged out of aircraft-grade aluminum. Knox holds essentials securely –- credit cards, cash, and the iPod nano –- yet still allows users to access their iPod connections. You can still slide your iPod in or out of all mophie RELO accessories securely because the Knox comes with a RELO-ready Radura case. Pricing was not announced.
