Purchased this for use on  Caribbean cruise.  What I found is that the belt strap was not long enough to allow the wallet to fit completely in my pocket.  That is to say, the top of the wallet was visible in my pocket.  I found this to be of little concern. Even with the top of the wallet being exposed the wallet never fell out of my pocket.
I used this as my only wallet and it worked great.  It was a little cumbersome at first getting cash or a credit card out of the wallet due to the short belt loop but after a couple of times using it became less cumbersome.  The big advantage being that my ID including a passport, credit cards, dollar bills, excursion tickets, and even change all fit nicely in the wallet and the wallet fit in my pocket.
