My wallets have evolved over the years. There's a collection of them on the top shelf in my gun safe. One holds emergency cash, one holds credit cards I don't use often, one holds expired credit cards (why I save 'em I have no idea), and one is a "rodeo wallet" with a built-in checkbook. Years ago I carried the traditional "baseball" wallet in my back pocket. I call it that because it had so much crap in it (band aids, coupons, receipts, etc.) that it was about the same shape as a baseball - and about as comfortable to sit on all day. Then I found out back pocket carry made you a target for pickpockets AND was really bad for your back, so the baseball migrated to my front pocket where it stayed for decades. A couple years ago the wife and I went to Scotland to visit all the places her illustrious ancestors haunt (her bloodlines go back to Robert the Bruce and William Wallis). I decided not to carry the baseball, and ordered a "minimalist" wallet from Amazon - it came two in a package, one black and one dark brown - because I prefer to travel light. Minimalist wallet holds a half dozen cards, a couple IDs, a guitar pick, and a few bills. And it's about a quarter the thickness of the baseball. Makes no telltale bulge in the pocket and weighs practically nothing. Plus it's supposedly RFID shielded. So once we got back to the good ol' US of A, I continued to use the minimalist wallet, which I use today. The baseballs sit in my safe and archive all the stuff I don't need to cart around on a daily basis. Plus, I have a full-blown medical kit in my truck among other things, so why carry that on my hip? Wal-Mart has some cheapo minimalists wallets for under $10 if you're interested. Once you go light, you'll never go back.
