Pickpockets don't look for tourists. They look for pockets.
A wallet outlined through denim. A bag hooked over the back of a café chair. A backpack unzipped in a crowd on the metro. It takes four seconds, and the trip you saved a year for becomes three days at a consulate.
Undercarry sits flat against your body, under your shirt, where nothing shows and no hand reaches. Your passport, your cash, your cards — all of it stays with you, from the airport line to the last night of the trip.
You stop patting your pocket every ten minutes. That's the whole point.
