Twelve South ( has unveiled the latest chapter in BookBooks: BookBook for MacBook Air, a new version of the company’s vintage book-style case.

The new version (US$79.99), designed exclusively for MacBook Air, is made of genuine leather and is hand-distressed to ensure that no two are alike, according to the folks at Twelve South. Weighing as little as 13 ounces, it sports two hardback covers that shield against impact, while extended corners and a padded spine cushion the MacBook Air in the event of a drop. 

A soft, chocolate brown, padded interior keeps the Apple laptop nestled in place when traveling. The two designer cornices on the top of the case indicate which side of the case is the top so you always open BookBook right side up.

The can be used as a traditional sleeve, or the two interior soft elastic bands can be slipped around the corners of MacBook Air to work with it inside the case. BookBook for MacBook Air is available for both the 11- and 13-inch MacBook Air.
