The black Artificial Intelligence 13 V3.0 Laptop Case from Think Tank is a slim, compact water-repellent bag in which you can store your 13" laptop or 10-11" netbook. It also contains enough space to store cables, documents, cell phone and adapters in its expandable, bellows-style pocket.

A strong YKK zipper guards the entrance to the bag that is made from strong rip-stop nylon. The hardware is metal with D-rings that provide additional durability. A removable, cushioned shoulder strap provides comfortable portability.

In addition, there's a handy secure rear document pocket in which you can store collateral material. For business purposes, there's also a card slot for when you meet a contact and quickly need to exchange info. This case eliminates the need to carry around bulky laptop cases.
