Timbuk2 Classic Messenger

This bag is perfect for my needs. I walk to work everyday with the size small messenger bag slung across my shoulder; it holds my lunch and an umbrella among other small necessities; and has plenty of room if I need to bring my laptop home. It's very well organized with compartments for pens, eyeglasses, a water bottle, as well as a secret zipped pocket that's big enough to put documents in - which I didn't realize it was there for several days after using it. There's also a couple of pockets on the outside that could hold smaller, flat items. I like how flexible it is such that it handles items most Messenger bags of this size couldn't. When I have my soft lunch cooler/bag in it, it doesn't seem tight or unnatural, and a floor forms at the bottom, magically creating room for more stuff. One improvement I would like to see is an outside pocket that is accessible without having to open the flap; a small flat pocket I could put my key card in - which I need to get into my building. I understand the larger bags do have this feature, but I feel this bag could accommodate one as well. Nonetheless, you won't find anything better as far as a messenger bag that combines durability and functionality. I'll probably get the extra small size bag as well for train rides to NYC when I just want to take my iPad.
