Review on Pacsafe Coversafe Anti Theft Blocking Neutral Travel Accessories ~ Travel Wallets by Roberto Bates

The bottom of the bag is only 6 inches wide, the top of the bag is 8 inches wide. The pocket is 3 3/4 inches deep. The US dollar bill is 6 1/4 inches wide, so if you have a stack of bills with stripes, they won't quite fit to the bottom of the bag. (Please note that US bills tend to be smaller than foreign bills, so if you're traveling with a wad of Euros or Yen, this case is not for you.) The belt is only 5/8" wide - many belts of this style use it a 7/8 inch belt. When fully extended the belt is 45 3/4" long - if your waist is larger then this bag is not for you. The strap is not elastic but an elastic piece is attached to the bag at the end to keep the strap taut .(Length 45 3/4 inches with elastic fully extended.) If you're just using this money belt to hold some credit cards, some folded bills, and a key while you run or whatever, this device will work beautifully. The RFID blocking is a good security feature.For international travel I would suggest something larger but this device fits in a passport.This device is zip only so it can be worn through airport security and will not set off the metal detector.
