Crimes against property are common in Latin America, and tourists are frequent targets of mugging, pick pocketing and hotel room thefts. Even if you have an in-room safe, you may want to carry your original passport and some spending cash. For example, although it is a frequent practice to carry photo copies of passports in Costa Rica, this can cause problems if a night club or massage parlor is inspected by the police.
Often, best way to carry a passport is in a Concealed Neck Pouch, which protects it against wear and tear. In warmer weather a neck pouch can get sweaty, and a good alternative is a belt attachable Hidden Pocket. Always keep a little cash in your pocket, or else a potential mugger may not believe you are broke. Also, having small change at hand avoids showing a pouch or pocket in public places.
Die hard travelers should always keep a little spare cash in a safe place, so as to have something if they get robbed while hiking between bus terminals and isolated areas. A good option is a Belt with a Hidden Security Pocket. More secure than backpacks, a Pacsafe Sling is perfect for keeping valuables like cell phones and camera equipment in front of you.
