At Walmart for about a buck or so, you can buy a light weight plastic painter's tarp. I think they are about 10'x 12' or so Spread it out on the ground to lay the meat on as you are processing in the field. Really helps keeping the meat clean and it weighs only a few ounces, folds up to about 2" x 6" and 3/4" thick
I carry a section of Tyvek house wrap in my pack. It weighs almost nothing and can be used for all kinds of things. Water and wind proof, tough as all get out. Nice to spread meat out on as you quarter or debone.
