What things do you recommend to keep in your back pants pocket? What's small, comfortable to sit on, worth carrying, but inexpensive and easy to replace in case it falls out when you sit down? I've often read in this thread that other people, like me are reluctant to keep anything valuable in their back pocket in case of loss or pickpocketing. For decades mine have remained empty. Then I got into EDC and I'm thinking more about using more pockets to carry useful stuff. So now I'm thinking about whats cheap and replaceable, but is useful to have on me. What I'm carrying now: - fresh Kleenex tissues in my back pocket. I can sit down, I don't care if it's stolen, and it's really useful. - a printed page of info on standard letter paper folded down pocket size into 1/8 size. This week the paper has my latest list of backpacking essentials I'm reviewing for my summer trip. This gives me a useful personal activity if ever I have a few minutes to kill -- while waiting for someone, for appointments etc. Again, I can sit down, is replaceable, and useful. I wouldn't keep printed confidential material, but something fun to read later. Maybe some sudokus? http://www.pocketmod.com/ is another good idea, as long as it's not irreplaceable / confidential. Any other ideas? Thanks guys!
