Have the Samsonite belt Safe used on a three week trip and would recommend it unreservedly. He is very pleasant and unobtrusive to wear under clothing and in the two compartments can be easily his passport, money, credit cards and mobile phones (and even more) at the same store. The rear compartment is inside ca 22 cm wide (where the zipper is only 16 cm wide) and ca 11 cm high. The front compartment 14 x 9 cm, (again the passport easily fits in). For me, he got the job done very well satisfied.
