For those touring in forested area's the hennessey hammock is great. I have slept over rock's, delicate forest vegitation in comfort while not leaving almost no impact (There is still impact from walking around and so on), and been subjected to all manner of wind and rain. The hennessey is great. There is great deal of flexebility in it's set up, one can position the built in tarp high over the hammock with the wing's nearly horizontal in pleasant weather (or hot sunny weather) for the view's and to take advantage of every little breeze, or position the tarp low and close to the hammock with the wing's low for inclement weather. The hammock bed has elastic tie out's (give major room inside) that the tarp can be clipped to, this hold's the tarp low to the hammock and the elastic hold's it taught preventing it from flapping, set up this way the hammock shed's wind amazingly well. Hennesseys also have these wide strap's to go around the tree's so they do not damage the tree. The color's are great, my hammock blend's right into the landscape, the fly is the same sort of colour as the moss (now MSR) tent flies. And the bed is a charcoal grey. Maybe because I'm young and limber, but I can change in the hammock no problem, it is actually fine for changing, very private.
The hammock is easy to set up because a built in ridge line insures that the bed has the corect sag to be comforatable. It is built with the mayan design, you sleep on an angle which results in an almost flat, but very comfortable and suportive sleeping surface. In cooler weather it can get a little cold through the bottom, but I simply sleep on my thermarest, it takes a bit of practice to get the hang of sleeping on it but it works great. The ridge line also give's you a place to put all your stuff, I put my raingear over the line and push it right into the corner of the foot end, and hang my clothes on the line. There is a mesh pocket ont the ridge line in which I can put my glasses, flashlight and other such stuff. It's so cozy inside, it's a hanging tent, not just a hammock.
I normally toss and turn a lot when I sleep, but in my hammock I basically pass out, I wake up in exactly the same position I went to sleep in, and I wake up more relaxed and refreshed then I have ever woken up in a tent.
The coolest thing about the hennessey's is you get in through the bottom. There is an entrance slit at the foot end, that extends to the middle of the hammock, to enter you pull it open, walk into the hammock, turn around, sit down, lift your leg's up and lie back. The geometry of the cloth make's your weight hold the slit shut, even if your moving around in the hammock it won't come open by accident, you have to try to open it. Getting in an out is even easier than a tent, no crawling around on the ground, just sit down and lay back to get in or sit up and walk out to leave.
