The tent alternative.
Packing light means camping in a hammock with a ridgeline tarp to protect you from the elements. Many people prefer this to a tent because it's so portable and you're up off the ground. This Hennessy Hammock is made from rugged 210D Oxford nylon and includes attached mosquito netting, detachable rain fly, support ropes, and stuff sack with set up instructions on back.
