I bought this pocket for our trip to Europe (Rome, Barcelona and other spots) based upon recommendations from friends and family.  I must say, that a lot of the theft threats were overstated, as long as you stay in the tourist areas.  With that being said, I did use this pocket on several days abroad.  If you're gonna take a hidden pocket, this one is it.  It's so light and comfortable, once I put it on, I literally forgot that it's there, but at the same time felt secure cause the pocket is INSIDE YOUR PANTS!!  The comfort was really surprising, especially in the summer heat of Italy.  It even has a black and tan belt loops so u can match your pants/belt and make it even better hidden. Anyhow, definitely recommend this product if you're in the market.
