I happened upon this thread, figured I'd toss my two cents in: I got one of the Magpul bifolds a few months ago, and am really loving the minimalist, slim wallet. My son has had one of the super small ones for a couple years, it's great but too small for me. When they came out with the bifold, though, I was in:

RF welded polymer - It's not going to stain or have liquid damage, very light. Space for maybe 8 cards, cash, etc. Texture is a little grabby so it won't slide out of a pocket, as opposed to the burnished (if that's the right word) feel that leather gets over time where it's all slippery.
I switched from my old leather one right before a trip to Amsterdam, and had humorous moments the whole trip "WHERE'D MY WALLET GO?" and there it was in the pocket. So light and small compared to my old one.
Worth checking out.
