Okay, so I need a backpack or messenger bag or something to carry around my stuff. I am, right now, consulting & going to school & teaching, so I often commute downtown once and then go to two or three different jobs, and need my stuff for each one. So right now, I have a black canvas L.L. Bean backpack with a laptop sleeve and two main pockets and side pockets for a water bottle and an umbrella. This is my preferred bag, but it doesn't exactly look professional. So, I am looking for a decent replacement, but keeping in mind that I generally walk a few miles/day carrying at least a few pounds of stuff.

I need a suggestion for something that is both fashionable and comfortable. I don't mind shelling out for it, as long as it is durable enough to last me a while. Any suggestions are much appreciated!
