Years ago, at the advice of a good friend, I began carrying a pack hammock and tether straps in my pack whenever I hunted elk or mule deer in Idaho's high country. During the mid-day lull, I fix it between two trees, take off my boots, lay in the cradle of the hammock, and sneak in a quick nap. Pack hammock sets, like the ones from Wise Owl are inexpensive, easy to set up and take down, and a real asset in any camp. I keep one set under the seat in my truck, just in case, but you can stash these things just about anywhere; they're lightweight and pack down into a stuff sack that's about the size of a big grapefruit. Made from 210T parachute nylon, the hammocks are strong and weather resilient, and there are two carabineer clips to attach it to the tethers, which are both 9-feet long.
