I like things that are simple and rugged. Add a few strips of MOLLE webbing and all the better. The Cargo Works MacBook Air + iPad Sleeves fits these criteria. As the name cleverly implies, it holds a MacBook Air in a neoprene zipper pocket as well as an iPad in a front flap pocket and the webbing on outside can be used to hold pens or attach other items. All with a tactical military style. For durability, the exterior is made of 900 denier polyester canvas with YKK zippers. Available in 11″ MacBook Air version for $29.90 and 13″ MacBook Air version for $34.90. Head over to Cargo Works for details, and while there, also check out their MacBook Module Sleeve and MacBook Organizer.
