Since I have no place inside that SHE will let me hang, I built a hammock stand for the yard, works perfect. I hung my NX250 last Friday and have slept in it every night since. The low temps each night have varied from a low of 50* to a low of 65*. I have not used any bottom insulation other than what is provided by the empty pockets under the hammock. There has been rain three nights but no heavy winds. I have been able to sleep comfortably with only top cover and light clothing. I am sure that I would not want to winter camp with no bottom insulation, but for summer nights I seem to have no problem. I plan to give it a few more nights at least, just to be sure. If I haven't said so before, I sure do like this hammock and how I sleep in it. Happy hanging, ya'll.
