This comes up a lot.  What do we use to carry our passports, boarding passes, etc.  I found this a couple of years ago, and now, it's the only item I use for all of our papers, including our cash.  It's from Maxpedition. I posted the video because that gives you a better idea of what the item can do.  The only thing I changed, was the neck cord. I found it biting, so Imswapped it out for an old camera strap I had laying around.  I bought one for each of us, but I really only need one for both of us on any given cruise.  Hope this helps.
