Quick thought about bottom insulation.
In double layered hammocks,using clothing between layers for a bit more insulation in mild summer/spring weather.
For example put two fleece or synthetic/wool/down midlayers and 1-2 baselayers.
Would it work??
Or will the minimal loft minimize any agains,due to (convective i think is the word,when its the air) heat loss?
Also it wouldnt move around a lot compared to some annoying slippery pads.
