Getting ready for my first outing in a hammock and it will be cold. I am on a strict budget and need to stay warm so I used an old sleeping bag tied to a paracord ridge, old yoga mat from wife with a camo blanket and my 0 degree Kelty as an OQ. Worked well in garage, temp down to 40 and I was warm. Not the best but worked well, slept in it last night. I am thinking of doing the poncho liner mod to cut down on weight when funds allow.
