Up for sale is a vintage Adventure 16 goose down mummy bag, likely dating to the late 70s or early 80s. Unlike most mummy bags, the bag can be completely unzipped and used as a quilt The zipper pull faces inside the bag instead of out, which I'm not sure is a manufacturing defect or something they meant to do. When zipped closed, it measures about 84" long x 27" wide at its widest point, tapering down to about 16 at the foot box. It has about 9 of loft.
