I had purchased a leather wallet earlier to replace my old, ratty leather wallet but that new one turned out to be twice as fat as my old one after loading it up.  I then bought this one and it holds all my stuff without adding a lot of bulk of its own.  Being Tyvek it is somewhat slippery, but not unduly so.  The color is advertised as black but it looks almost like a very dark brown.

The current picture shows a yellow credit card of some sort sticking out the right side.  That is because there are pockets on each end of the wallet.  The problem I saw was that, unlike the pockets inside the wallet, the outside ones (given the Tyvek is slippery) would let the cards fall out if you held the wallet "wrong."  My solution is to use those outside facing pockets for cards I don't access much (and won't give me financial grief if I lose them), and then wrap a couple rubber bands around the cards so they aren't slippery so they won't slide out easily.  The inside pockets are much more protected and that is where the credit and debit cards go.

I do miss the plastic windows as you have only those two inside pockets so you have to pull your pack of cards (library card, credit card, debit card, store card, driver's license, etc.) out and then pick out the specific one you want, but those plastic windows added a lot of bulk of their own.
