Question: Does this hammock sleep flat or banana shaped?  Also, would it be possible to sleep on your side or stomach?
Document: Last, you also need to go order the hammock "snakeskin", it makes set up and tear down a breeze. You can get it atHennessy Hammock Snakeskins #4. This has replaced the tent I have been using for just about 15 years!!! !
The comfort and convenience of this hammock is amazing! I tried the ENO hammock and took it back. Hennessy makes a quality product. Camping with a tent and a sleeping pad is a thing of the past. No comparison to the quality of sleep I now get in the hammock. The rainfly keeps you dry even in blowing rain.
I have used this hammock on multiple trips, others,  usually laugh because "that's for warm weather." spend the night dry and sleep soundly and am not sleeping on any roots! It does get a little chilly because of the open bottom but by throwing down a Mylar blanket and sleeping on top of that it keeps the heat in and makes the breeze underneath is unnoticeable. Packs up in a quarter the time of any tent, is about 1/3 the weight of a tent. Great product.
Kept me warm and dry. First night out of the box I set it up and it snowed then rained with high winds and not a drop. The wind didn't bother the hammock much as the guidelines kept it steady.I am thinking of suspending a mesh hammock under my hammock for my bags, gear, daypack and shoes, to keep them off the ground.The other item to bring would be a line level, to help with leveling the hammock.All in all a very simple and comfortable design.
I do frequent camping trips with some coworkers. I usually set up this and my truck bed tent to sleep on a cot. Both work well. For colder weather I suggest using a bad under your sleeping bag so your back isnt exposed to the night air. Very comfy!
My friends in tents woke up tired and grumpy. I was refreshed. This thing is awesome. The only issue is getting out and back in after a piss was no so much fun. While you are in it and sleeping though it can't be beat.The setup is great because you don't have to worry about the ground (sticks, stones, slope, exc.). The setup is also fast, especially if you get some carabiners and rappelling rings!
This is a great hammock but buying direct gets more bang for the buck. HH gives free snake skins and often has deals for free upgrades or additional items.
I absolutely love it! Buying the snakeskins is a MUST and if you aren't an expert on knots, buying 2 carabiners and 4 descending rings will make setting the hammock up an absolute breeze. I have a total of $200 invested and couldn't be happier with my decision.
The idea of this tent hammock is great and i bought it on the recommendation of a friend. I found it extremely difficult to get into and almost impossible to adjust position or sleeping bag once in. Only positive is that is very easy to set up. If you have no problem sleeping like a pretzel you will love it
Thus is an excellent hammock. I've used this in the jungle in Brunei and am taking it to Malaysia. It is a must for jungle operations. It keep relatively quick. If you buy straight from HH then you get a free snake skin but i have a prime account so shipping was free. It worked out $10 less through amazon.
