Besides the USGI poncho, I carry one of the cheaper camo ponchos and a couple of industrial strength 55 gal drum liners. I also carry an inexpensive 3/4 Ridge Rest (Therma Rest) foam pad that does a decent job of helping to insulate from the ground. Building up a debris bedding area and using a pad on that works well. I've been considering a basha to replace the cheap poncho. It will add a little weight to my rucksack, but is worth it I think.
