Most homes depend on electricity for warmth but without it there is a danger of hypothermia. When I build debris shelters in the woods one of the main design elements is to limit the area that needs to be heated and to provide insulation from below. One popular suggestion to apply this technique to a home situation is to put a small tent on top of a bed to capture body and breathing heat.

A self standing one or two man tent is a logical choice to mount on top of a bed dependent on the mattress size. In that I did not have one of those types of tents I used my improvised “X frame” poncho tent as a substitute to illustrate this concept. In fact, a suspended rope with a tarp draped over the top could be used instead of a tent or in addition to it.

The whole point of putting a tent on a bed is to capture the limited sources of heat and to insulate yourself from the surrounding lower temperatures. Alternately, a nested double tent could be used in the living room with padding on the floor. Care should be taken to not use flammable or carbon monoxide producing supplemental heat inside these tents but hot water bottles could be brought inside or perhaps your four-legged furry pets.

Occasionally in social media I’ve seen what looks like a three person hammock which piqued my interest but in fact it is a suspended tent that is officially described as a “three-person all-season suspended camping tree house tent”. It is basically a three anchor point triangular canvas covered with an integrated mosquito net canopy. It comes with an optional rain tarp.

I wondered what it would be like to spend a night in one with two other adults, thus testing the advertised three person capacity. As it happens, some friends of mine own one and had it set up. With their permission I was able to share an overnight experience with my two adult sons.

The entry is very unique. You can enter it from below via a zippered triangular hatch in the center. This reminded me of my Hennessey Hammock that uses a Velcroed slit for entry. In addition there are three zippered panels available for entry or egress on the sides of the roomy mosquito net canopy.

After all three of us entered the tree tent it seemed that one end of the triangular canvas floor was a little high, so we tried to correct it. The tree tent is suspended using ratcheted straps. We maxed out the tension on the lower end, and we lowered the anchor strap with a little slack on the high end. We felt that it became more comfortable but may have contributed to the ensuing bowl phenomena that we experienced that night.

The somewhat flat surface of the tarp reminded me of a trampoline but it had less support points on the perimeter so it was more flexible and as we entered the tent it would sag in the middle. When I brought in my gear it would slide toward the entry point.

When two persons share a double hammock there is unavoidable major bodily contact but with the large tree tent canvas I thought that this might be avoided but no such luck. It became apparent as we gathered inside that in order to have personal space we had to lay with our feet to the center and heads at the outward points of the triangular canvas. There is an integrated strap at each point so it is uncomfortable to lay in the center of these areas. The outward edges between the anchor points were unusable as we were inclined to roll laterally inward.

In an effort to not disturb my sons by touching their feet that night I ended up in a fetal position in my corner taking occasional stretches. I was pleased that whenever one of us would shift our sleeping position during the night the resulting shaking was surprisingly minimal. Because we had warm weather we did not feel cold from below that night. We used our sleeping bags only as blankets and realized that we would have slid inward if we had slept in them. Perhaps this problem might have been different using other anchor points and mounting adjustments.

My opinion is that this is a novelty item that is best used for semi-permanent camps or back yard setups. It definitely favors being a tent vs. a hammock. It became evident that my expectation of a hammock was in error but sharing a warm Summer night together with my sons made this a rewarding experience.

After debriefing my friends the next morning they are considering moving the tree tent to a more suitable area with even spaced trees which may make for better anchoring and more even tensioning. If they do, we have been invited to try another overnight hang to help evaluate what they hope will be a more comfortable experience.

My friends who owned the tree tent invited me back to try it out after they had tightened it up according to the manufacturer’s instructions and it was more comfortable. I tested it with only one other available adult instead of having my two sons with me but it did exhibit more pronounced laying areas along the sides as apposed to our use of the the corners of the triangular canvas. The bottom line is that a hammock and a tree tent are two different structures and therefore they are set up differently. I had applied my hammock experience to a tree tent when I had adjusted it but apparently that led to my overnight comfort demise. So, lesson learned. Hammocks and tree tents are set up differently and each one offers a different lounging experience.

I carry this in my Bug-Out-Bag (BOB) along with a sheet of water intrusion barrier material that I use for a ground cloth. I don’t carry a mattress so I selected a spot that had a layer of leaves that I hoped would be sufficient to provide enough thermal insulation from the ground in addition to some degree of comfort to lay on. It was also quite flat as I try to avoid an inclined surface to sleep on.

For the most part I laid on my side with my knees bent as if sitting on an imaginary chair. Alternatively I would straighten my legs and sleep on my back. Because it wasn’t raining I knew that I could afford to poke my feet out from under the shelter if needed but I could have changed from a sitting position to a “V” position if needed to be completely covered.

The “X” frame inside provided a nice place to hang my key chain light, but my smart phone provided plenty of light when needed inside the shelter. I moved my pocket knife from my side to a more comfortable position in my shirt pocket with the added benefit of quick access if needed. I also used a bug net over my head at night, keeping it extended out from my face. As an added bug/critter repellant I rubbed tea tree oil on my ankles, wrists, neck, and forehead.

The only thing that I used that I don’t currently carry in my BOB was a down sleeping bag. This causes me to rethink my strategy and perhaps consider preparing different BOBs based on the circumstances that would necessitate my emergency egress.

For starters, rip-stop material is really tough stuff and is not prone to tearing and if it should get a hole it will not grow in size. Because of this strength it can be adapted to function beyond it’s original intended use as a garment and into a tent-like structure by using fiberglass knock-down shock-cord rods as an “X-frame” being tied in the center with each end anchored at the corner grommets that are incorporated into the poncho design.

My poncho measures 54″x80″ and provides good coverage when configured as a tent. I am 6′ tall and have found a couple of positions to lay where I can be completely covered and yet stay somewhat comfortable. I can lay on my side in a sitting posture with my legs bent. When I feel a need to stretch my legs I remain on my side and form a “V” with my legs outstretched. While in this position there is plenty of room for my Bug-Out-Bag (B.O.B.) to lay beside me.

Should it happen to be raining, you could trench around the drip-line to divert water or build up a layer of insulation beneath you to keep you warm and comfy while at the same time separate you from the wet ground. If it’s not raining I suppose that body parts that protrude out from under the shelter wouldn’t really matter, but I prefer to be covered completely.

I carry my poncho in my B.O.B. along with an ENO double-sized hammock. I decided to try using the poncho as a rain-fly to cover the hammock. As you might see in the photo, it is slightly under-sized for rain but it could be used in a pinch with the sides held out with guy-lines. At the same time it covers the top opening of the hammock to help keep out bugs.

In either the tent or hammock rain-fly mode the camouflage pattern helps to provide a stealthy approach to camping which in some emergency circumstances could work in your favor unless you want to be highly visible in which case you would want to use a blaze-orange or other bright color to gain attention.

If I decide to upgrade yet another time, it would probably be for a larger size or a different camouflage pattern but I am quite pleased with what this poncho has delivered and look forward to testing it out in the field.
