You may think that condoms are unneccesary if you're heading into the wilderness alone, but think again. The small and lightweight condoms can hold over a gallon of water easily, which is enough to extend your life by a day. If you take issue with the idea of drinking water from a condom, you can also use your jimmy cap to keep lifesaving materials dry. Again, nothing is worse than wet matches.
