I recently hung in weather that go down to about 50 degrees F at night. I brought a MYOG fleece underquilt and it wasn't quite enough... Since the wife has taken a liking to my Blackbird (and my 900 fill down underquilt) I am looking for cheap options for warmth during summer hangs.
I've seen people with huge pieces (covers entire underside) of thin foam in single layer hammocks and I'm wondering if that keeps you warm enough? How do you pack a piece of foam like that? Is an inflatable pad (I have plenty) with SPE better?
What is the going design for a somewhat compact (warm weather) MYOG underquilt now-a-days?
