This holder is well made.  It had a belt loop, so you can use it that way also.  I used it around my neck and inside my shirt long enough so it hung down inside my pants.  It was kind of bulky under my shirt, so that is why I adjusted the string to hang down lower. No problems with pick pockets.  In the airport, where they ask for your passport 800 times and have you walk through a screening device, I took the pouch and put it in a larger bag of mine going through the conveyor belt and wore it outside my shirt at other times in the airport.
