I bought this travel money belt for my trip to Spain.  I wore it to and from Spain but not during my 30 days in the country.  The belt gets a little bulky and is not as easy to conceal inside my clothes.  Second, I would sweat in the area which would lightly dampen my money.  I bought a cheap purse in Spain to use during the trip.  While this belt has a great concept, I think it is better to use when going to the airport so you have easy access to your passport.  It is possible the material needs to change to make it breathable.  Wear loose clothes with it and for shorter periods of time.  My Spain trip was 17 hours going to and 16 hours coming from.
