The difference i believe is that your sandwiched between the pad and your quilt and the quilt is connected to the sheet which is strapped to the pad. You can roll around or switch positions without rolling off the pad. Even though the zen bivy set up i am looking at is a few ounces heavier then the argali bag, it is atleast a pound lighter then my current 20 degree sythetic bag.Doesn’t that pretty much make it a sleeping bag put together with clips instead of a zipper?
