Ok. My turn.
When I played reenactments I carried a tarp that was usually set up in a plow point, I think y'all call a half pyramid. I often had a small canvas my blanket was rolled into that became the floor. I used it in 100 degree weather, rain, and snow.
Packing it was heavy because it was canvas. The tarp, blanket, water, food, gun, etc weighed out about 50 pounds, give or take. Not for extended trekking.
I would think in my situation, comfort would be secondary to survival and mobility. I need to get home. I've spent many nights in or under a poncho.
That being given said, I've got a small $30 tent I can pack that weighs about 6 pounds. It is disposable as far as I'm concerned. I really think a good poncho and sylnylon tarp are on my buy list for this year. About a hundred bucks for the ones I'm looking at, and weigh a couple pounds together. Paracord and light weight tent stakes and I be good to go.
