I have a bag I call my "manpurse" (only among friends, though, like all the strangers reading this). But I took the strap off and attach it to my belt so it isn't so weird.
It's really handy, have to admit. Holds my camera, wallet, glasses, nose-spray, keycards, money, whatever.
This year it is getting replaced with one of those airport lanyards, though, that hold your passport, plane tickets and everything else in a thing that hangs from your neck.
