In my wallet, I keep a couple of extra bandages, emergency info, an extra house and car key, and that's about it besides the normal stuff. I like to keep the wallet slim.

The nylon pouch is small enough to keep in my front pocket. Its about the dimensions of a deck of cards and has a key clip attached. You can get them at Galyans sporting goods stores under the name "Marsupial Pouch."
