Now, let's talk about cover. Many think a tent offers more secure shelter, but that's only in theory. Take rain, for instance—if there's a significant amount of precipitation, the air inside most tents will still feel damp and clammy, even with sealed seams and waterproof floors. A hammock, on the other hand, hangs high above the mud and streams of water that form during a downpour. As long as you have a tarp or some sort of covering overhead, you'll stay warm and dry.
