Ok so I got the fore-arm tattoos, the beard, ratty smelly wool jersey, black dickies rolled up and just picked up a chrome bag; what more do I need to look like a messenger?

I just upgraded to a chrome bag (the one size smaller then the kremlin). This bag is freaking huge, when I picked it up my old bag only took up about 1/3 of the room inside. I was looking for something I could live out of for at least a week and this is it. It's pretty comfortable, but I kinda wish there was some padding on the back, my metal lunch box has been biting into my back. I absolutely love it.

Does anyone have any tips or secrets they use to get more out of their chrome bag?
