Veteran Travelers...I need a recommendation

[HotPockets]

Hey all,
In a few months I'll be traveling abroad and I'm looking for a decent bag to use during the day. Anyone have any recommendations on something that could fit all the daily necessities but doesn't look to bulky? Some kind of man bag maybe? Looking for it to hold ID, cash, plastic, maps, ipod, camera, sunglasses, maybe small souvenirs. Does something like this even exist that isn't too clunky but is relatively secure? Anyone have any ideas?
