Superleggera Pro for iPhone 4/4S ($13) is AE Tech’s/Acase’s take on a dual-layer rubber and plastic case.
It’s a surprisingly protective option, with full coverage for all the ports and buttons built into the removable inner layer, including flip-open doors over the headphone and Dock Connector ports.
The plastic shell — available in a variety of colors — then fits over the top, offering some structure and extra protection.
