I already have a very RFID blocking wallet that is smaller than this one, however when traveling to countries where most transactions are in cash rather than with credit card, it became an issue. I would end up having to pull out cash that was tightly folded and fumble around with it.Getting this wallet with the money clip and RFID blocking was the perfect solution. While I think it could probably be a little bit smaller, it's still ultra slim and the money clip helps make cash easy to access. Very happy with this purchase!
