Pouch for documents, ie passport and flight tickets? Money belt, strapped around the waist. The actual money belt is microfibre, anything paper goes into a zip-lock bag to prevent it from getting wet. (Sweat, rain, spilled drinks, etc.)
Money: Wallet that goes around the neck, the string should be long enough that I can easily put it into the pockets of my pants. It then comes out with unnecessary fumbling under the t-shirt, but is still safely attached to my person.
Needless to say that I keep cash, plastic and passport all seperate - my rule is that I should be able to keep going with the other items should I loose one or two of the above.
