I have a Thinktank Airport International 2.0, and while great it's a bit heavy. The Cinebag linked above is a good bag too, as it appears as a laptop bag and is generally not weighed as a carry on.
Carry on weight is becoming more and more important. Flying with Singapore Air I can carry on two pieces of 7kg each in business or one if flying economy, while Philippine air only allows one at 7kg and they're pretty strict about it, regardless of what cabin class you're in.
A photo vest loaded down with glass, bodies, and so on is a good option evidently, to make your carry on bag appear lighter, then pack it all back up once you're through security and in the terminal, or better in a lounge with less eyes on you!
