The Ronin Wallet is a total lightweight. Its profile is thin and its construction is minimalist. So you might thinkâ€™s just a handy way to carry around some cash. Think again. The lightweight interior is wrapped in the same outer material as our fiercely tough Dart packs. The Ronin is lined with an RFID blocking material to help protect your identity. The thieves will have to move on to another target. Youâ€™ve got a tiny safe in your pocket.
