Condoms are notoriously difficult to find in developing countries. The locally-made rubbers that you can find will have a much higher breakage rate than condoms manufactured in the USA, Europe, and Japan.
Condom sizes are also different from what you might find in the USA. Condoms in Asia and South America are sized several millimeters smaller in both length and diameter than their counterparts in the United States. Asian “large” size condoms are sized smaller than the “regular” sized condoms found in the USA.
Additionally, if you are latex sensitive, you are unlikely to find any non-latex alternative condoms in the developing world. You will stay much safer from sexually transmitted infections if you bring condoms from your home country.

Bring condoms from home if there is even the slightest chance you might need one.
Condoms (the unlubricated ones) also work well as emergency water carriers in a survival situation. It’s useful to carry a few on your travels, even if you don’t plan on using them for their intended purpose. You can fill a condom with a tremendous amount of water. If you use this water transportation method in a survival situation, place the condom full of water inside a sock for protection during transport.
Don’t tie the neck like a balloon. It will be difficult to untie when you need to get to the water. Use a piece of string or cloth to tie off your emergency water carrier instead.
