I've had the urge to make a cuben wallet ever since I saw pictures of one on Backpacking Light. One of my main problems wit a wallet is carrying my passport. Being an American living in Germany, I'm required to carry it. I designed this to hold my passport, 6 cards, and money. It's a bifold design with 2 card pouches. I reinforced all of the edges with an extra layer of cuben. It only added about 1 gram, and made it a lot stronger, so it was well worth it. The Velcro closure make sit sit better in my pocket without sliding around and deforming.
