The new MacBook may be small and ultra-slim, but WaterField Designs is still banking on the fact that users will be looking for stylish and elegant ways to protect and carry it. To that end, the company’s new Zip Brief ($179) aims to provide a sophisticated yet unobtrusive design for Apple’s slimmest MacBook ever. The exterior is made from naturally tanned leather with waxed canvas or ballistic nylon, and the bag is designed to be TSA-friendly, opening fully for airport security inspections without risking anything falling out.
