Secure your valuables by tucking them into a "waist safe" that is tucked under your shirt. It can't be pickpocketed nor can the RFID inof be read by nearby scanners. There are two different sections to secure your Passport, ID's and currency. It's made from a nice lightweight fabric that feels soft against your skin. The strap adjusts up to a 50 inch waist. The stash itself is 11 inches wide and 5 inches tall.
