I ordered MARPAT color liner. It is the newer version with the zipper installed to make it a lightweight sleeping bag. The outside material is nylon ripstop similar to parachute material, MARPAT DIGITAL camo. The inner color is a coyote tan or flat dark earth color. It has shoe string style attachment points to be tied into grommets of a poncho. There isn't a "neck hole" in these. When fully unzipped, it makes a a large blanket (I would say a full size bed). I do not have an actual weight, but overall it is very lightweight.
I hope this help answer the questions you had.
