I purchased this item and a similar item by Eagle Creek.  I wore the Rick Steve's product my entire trip.  It is convenient, well hidden, great pockets, and just large enough that you don't have to fold most currency.  You really have to look to see that this is hidden under your belt.  Very comfortable!  I highly recommend and have purchased two more as gifts for my friends who travel frequently.  This beats any money belt, strap around your neck, or something affixed to the calf of your leg.
