I have the Eagle Creek and use if for international travel, or flying in the US.
Plastic buckle makes security a bit easier.
I carry a few $100 dollar bills, a twenty, a copy of my passport and a list of important numbers for the country in which I am traveling.
I am not sure how much useful gear you could comfortably put in there.
