ok guys and galls. im thinking ahead here and need some info.

When i was at my hang in santee, i got COLD not having a TQ. I did have a poncho liner tho, and that made me happy as heck when i threw it over the ridgeline and got toasty warm REALLY quick.

now, im thinking about making something to copy that theory. but a PL is heavy.

so, can yall tell me what properties of the PL made it work so well to retain heat? i know it has insulation in it, but i didnt know if that was it. it didnt completely block the wind when it blew hard, but it did a dang good job.

is there a single layer of material that would work similar to the PL to keep in heat and create that greenhouse affect?
