Bought this specifically for a trip to Barcelona, where we had heard theft was a problem. I wore it under loose tops, found it very comfortable - the adjustable elasticated strap worked well in this. It held our 2 passports, credit cards and extra cash, and gave a good feeling of security. Netting on back prevented it sticking to skin, although it did get a bit hot in the heat of Barcelona. An excellent addition to our travel kit.
