The briefcase has been overstuffed a time or two. No issues at all. The vegetable dye did bleed in heavy rain after the bag was redressed about a month ago. Wasn't an issue before nor since.
Let's be clear about what this briefcase is not. It is not a laptop bag and I do not try to use it as such. The bag is a small briefcase that carries comfortably. My umbrella, lunch container, pens, and a few odds and ends are frequently carried items.
The only design suggestions for improvement would be to omit the zippered compartments on the back and inside of the briefcase. They are unnecessary on a bag this size and the zippers would not last for the expected life of the briefcase. The other suggestion would be a nice liner on the interior. Otherwise the design is excellent.
