I found this great new product that is, in my opinion, far greater than either a money belt or neck pouch, and its a Passport Pocket.
My husband and I are traveling this summer and I couldn't fathom the idea of a string around my waist, or neck for that matter. When I get warm and things are constricting places, I get crabby.
The Passport Pocket has tabs that sew into your bottoms (4 sets included) and then your pocket clips in. I thought that it'd be strange, but even the Rugged Pocket is unnoticeable quickly after you put on your bottoms. Plus, made in the USA!
(Not my company, but a great experience with a gal, Rose, from Oregon)
