I had run into a fellow hammock camper when returning from a wknd hanging.
We got talking about staying warm, gear, methods, etc.

He mentioned something about draping a sleeping bag/ blanket over a ridgeline to help insulate.

After getting home I began to think about this a bit more, looked at my options, etc.

I thought that since I have a poncho liner (which already has tie outs sewn in the right spots), could I just hang the poncho liner from my ridgeline on my hammock?

I tried this in my living room, and it does appear to work very well, essentially turning my hammock into a floating tent of sorts.

My question is the effectiveness of this.

I would continue to have my tarp set up, but would the use of said "ridgline cover (? is there a real term for this)" do much in the way of warmth?

In theory, I would think it could, as it's trapping some of the body heat in a smaller space (rather than it being lost trying to heat the whole forest, lol).

Any pointers etc. would be of a great help.

here's a picture of what I did with my poncho liner (incase I'm not being clear in this post).
