easily torn, WORTHLESS when wet,expensive sleeping bags, but it ain't like I didn't try to tell you. Ditto the silly assed tents, bivvy sacks, etc. If I am going to lug it around, it's going to be MULTIPLE use, and not nearly so easily-ruined. Most of the time, u'd BETTER find something in nature that functions fairly well as shelter-sleeping gear, to camoflage you as you sleep, and help retain your body heat, keep you dry, etc. Lugging around lots of bulky, heavy, GLARINGLY man-made gear is pretty stupid.
