On a recent camping trip my nephew brought along a survival hammock. This lightweight, full sized hammock fits inside a small bag and easily opens up into a strong and durable, weatherproof hammock. We were amused at how prepared he was for any problems he might encounter. All within reach were his flip-flops, a hatchet, and a fly swatter. He was prepared for any emergency.
These hammocks are quite expensive, but for the serious camper and hiker, worth the expense.
