See my second post in this thread. I do not advocate that wool blankets are either lighter or better than current technologies. I am saying that they work, at one time they were the historical equivalent of "ultralight" camping and that experiencing the capabilities and limitations of that type of bedroll is educational.

I have some very good down and synthetic sleeping bags, along with some very comfortable sleeping pads that I use. I am old, have broken my back and neck in the past, and have some arthritis. I like my comfort.

When I was a young paratrooper, my commander did not think we should use rucksacks as they would overload us and slow us down. I could not find a way to attach the sleeping bag to my Load Bearing Equipment, and the bedroll was the best system I could devise that I could carry and jump out of airplanes with. It kept me alive in some bad weather, but I would not claim to have slept comfortably.
