The Tenba Messenger Daypack is a casual, understated, lightweight outdoor backpack on the outside, but serious business on the inside. It fits most 15-inch laptops, and even 17-inch MacBook Pro sized models. With 30 pockets, slots and storage spaces, it will fit every cable, mobile drive and accessory that"s needed. The camera compartment will fit a DSLR body with 2-3 lenses and a flash, and if a camera is not needed for the day, then the photo insert is removable so that the daypack can be converted to a perfect laptop backpack.
