Heading to Rome in May for a cruise and bought this so Italian thieves won't get me.  Great material, non-sticky-sweaty.  Plenty of interior room; I have my Euros (bills and change), Passport and credit cards in this belt.  Wear it under your clothes and nobody is the wiser.  It's not bulky and you don't even know it's there.  The belt is adjustable and it's very comfortable.  Highly recommend.
