Sub Kilo came today! It is a very slender bag but will work fine. I am awarm sleeper and will seldom zip all the way unless in gets very cold . I am right at six feet tall and glad I ordered the Long, as a reg would not have worked for me. Weight came in right at two pounds in provided stuff sack. I am going to make a silnylon stuff sack and drop a couple ounces. Weighs half what my old bag did so I am on the right track. Happy Trails
