I really like my thread wallet. I have been using them for about three years, and just saw that they started selling on scheels.com. The wallet is very minimalist, and allows you to really slim down. There is a main pocket for a few of your least used cards, and then two outer pockets (front and back) for most used cards and cash. The elastic holds your cards very tight. (I've had multiple wallets and I would sometimes argue that they are held too tight, but they don't fall out.)
Overall Thread makes really fun, and cool wallets. I'd recommend to anyone.
I have just attached them to my keys and that way I don't lose my wallet.
