While Chris' post yesterday is fine and all, I like my bags a bit darker. A bit more menacing, if you will.

Enter the Booq Courier. Dressed in graphite nylon on the outside, with a herringbone nylon interior. This particular example is for a 13-inch laptop, but the company makes other sizes, too.

Reflective piping lines the edges, making it a nice bag for bikers and walkers. The seatbelt strap looks comfortable and is adjustable. The interior has two pockets, with a hidden pocket along the back. The whole thing clasps shuts, nice and neat.
