PLUQ's! What's the big deal?
I've yet to use my no-sew with the added layer of insulbrite, but without added insulation I have taken it down to the low 40s and Had a little bit of a draft. i had it set up like the illustration then, but it wasnt right. Because of missing ties, mine is set up a little differently now. Instead of folding in half, I laid it out and folded the two sides to the center. I then poked holes in the new corners I created, and attached shock cord. I still have shock cord in the channels at the head and foot end to cinch it up.
This past weekend I took it on a trip where I expected the overnight lows to be at around 60, so I took out the insulbrite layer. It ended up being in the high 40s, and I was still warm enough, even though I didn't cinch the foot end, and was too lazy to drop my tarp out of porch mode to block the wind.

Pluqs don't stuff good. On the carpet in my house I can roll that thing up tight. Harder to do in a hammock, and I don't want to put it all over the ground.
