Against my better judgment, I am going to mention a Travel Channel article that just popped up in my newsfeed 10 products to hide valuables that shows a variety of things - flip-flops, hairbrushes, deodorant containers, scarves, and (interestingly) hidden pocket underwear. The underwear seems logical extension of the money belt concept - surprised RS didnt think of it first. Some of these (coke can, water bottle) I've seen before for hiding valuables at home but never thought of as travel accessories.
Anyway, not looking to start a paranoid traveler discussion, I just thought it might be of interest to some.
