Most hammocks attach to trees via removable webbing straps, or "tree-huggers," which do not damage the bark and leave little or no marks afterward.
Whereas it's easy to see a frequently used campground because of the effect on the grass, scrub and topsoil, the presence of a hammock camping site is much harder to detect.
However, this also makes it harder to stay warm when temperatures plummet, either during the evening or seasonally, as a sleeping bag will be compressed under a camper's weight, reducing its ability to trap air and provide insulation.
When deciding to commit to hammock camping most "hangers" trade their sleeping bags for down-filled or synthetic quilts.
The UQ is suspended underneath the hammock so the weight of the hanger doesn't compress the baffles, thus providing air pockets for one's body to heat and keep one warm.
The TQ/UQ sleep system is not only warm, but each quilt packs into the size of a grapefruit, or smaller, depending on temperature rating.
Another drawback is that a camping hammock requires two trees close enough to hang it from, and strong enough to support the sleeper's weight.
Many use similar lines formed into a constriction knot (colloquially referred to by the brand name "Whoopie Slings"[7]) for quick adjustment and setup.
These may be connected to the webbing straps ("tree huggers") using a lightweight toggle or a carabiner, or more uniquely designed connectors such as Evo loops or specialized metal hardware.
