1. Boxer Shorts Pickpocket-Proof - Consider placing an extra bag with a zipper on your boxer shorts.

2. Put your belongings in a plastic bag in there when going to tropical countries.

3. Sweat will not pass the plastic, and it takes a great pickpocket to steal your belongings.

4. Two Dollar Bills to the Rescue - When traveling I always carry 10 2-dollar bills. If my wallet is stolen, I can call the police and tell them to alert banks for anyone changing their bills.

Chances are nobody else is carrying them, and foreigners are usually do not question them.
