Review on DiLoro Minimalist Leather Travel Blocking Men's Accessories and Wallets, Card Cases & Money Organizers by Jon Delgado

If you don't mind the inside-out style, this would be a decent choice, like so it is minimalist wallet. It's thin and flexible. If you only have 2 or 3 cards and only a few bills, your pocket will still be tight. I wasn't entirely convinced to switch from my standard style skinny wallet though, hence not 5 stars for me, but definitely worth a try if the style appeals to you.
