I will likely update this later when I find something I don't like about it. For the last five or so years I've been using aluminum Sharkk wallets. I've wanted something that carried more than just cards but was also secure with a zipper and RFID blocking. Reviews and descriptions seem to vary on this one's RFID blocking capabilities. I will get the RFID sleeves in case. Others mentioned the outside driver license slot not being large enough, but I would rather keep it secure inside anyway. I don't keep many cards in my wallets, but I like to keep a couple of spare keys and would like to be able to put what little cash I sometimes carry inside it. I was concerned about the size but this is nice and compact, and fits in my side leg cargo pockets and front pockets without feeling bulky. It doesn't feel like pulling out and holding a checkbook or pocketbook either. Wearing a wallet in the back pocket has never been a preference of mine, and I only reluctantly did so in the past when I use to have a typical leather or canvas folding wallet. I posted pictures comparing the sizes of this and the aluminum Sharkk wallet.
