Any suggestions for an Ultralight EDC bag?

In an urban environment, you have to have it look like a messenger bag or a computer bag, and you have to have a wire coming out of the top and going to ear buds. It is the modern equivalent to the businessman's briefcase of thirty years ago.

I would definitely recommend this one. My wife bought me one, and I use it every day.

Sorry, not much help, but I had to laugh at the tacticool comment, it immediately made me think of the shemagh:

If you wear a tacticool EDC purse you have to wear a shemagh to complete the ensemble. ;-)

All joking aside, I've been carrying a Kifaru E&E pouch in khaki for the past 10 years+ as an EDC pouch, and it is perfectly sized for my needs, but wouldn't hold a laptop computer. Mine is the older version, that is not covered in MOLLE webbing, so it doesn't look AS tacticool as some of the newer stuff out there.

Always liked the bags from Freitag:
