The hardest working briefcase to come along in a while. Although compact in shape, it devours huge amounts of paperwork, files and the rest. Business Logic features include a pair of deep gusseted front exterior pockets with snapping quick-release leather closures; a zippered file pouch on the back; and thoughtful small interior pockets for iPod or cell phone, business cards and pens. The case is lined with nylon taffeta. Heavy duty carrying handle, detachable padded shoulder strap. It is no surprise that this is the best-selling bag in the Mulholland collection.
