I've been looking at my brain bag, and wondered if anyone had tried using packing cubes in one of the main compartments. It looks like you should be able to get a large cube with a little extra room on top. Has anyone tried packing this way? If so, is there enough extra room for a snake charmer or a small packing cube in with the large?
If that works, this would be an almost ideal solution for most of my weekend trips.
