Here is an example of an overly-exhaustive medical supply list. I obviously won't be getting all of it (especially in one bag!). I may get one bag now and a second matching bag as time and finances allow.
Obviously smaller bags like the Imago and Cafe bags won't hold it all.
This isn't so much a first responder kit in that I don't have to access it quickly or often. I think if I will be taking it out of the country again, I will have to switch it to a smaller bag, so size isn't so much of an issue.
Whatever bag I get, I'm considering the photo insert(s) (whenever it comes out) in addition to the various organizer pouches/clear quarter packing cube.
The Imago and/or Cafe bag will have to be a purchase for other uses! (Hmm, it sounds like I think I have extra money for all of this!)
