I have an Eagle Creek shoulder bag that I carried for years as a man purse, my wife called it my Bag Of Plenty (BOP) even back then. I carried it all over Europe with everything but the kitchen sink, and retired it afterwards.

No I compartmentalize rather than try to carry the kitchen sink everywhere, so opt for vest/coats with lots of pockets. After being stalked by a pickpocket in Paris that obviously coveted my BOP, and the contents, I decided discreet carry was the better option.

But I have BOP's in reserve just in case!
