Check the listing for details. Alpine Designs Down Rectangular Hooded Sleeping Mummy Bag. Color: Black, Condition: Pre-owned. Listed at 129.00 USD. Up for sale is a rare vintage Alpine Designs down sleeping bag with integral hood. It's about 84" long from hood to foot x 33" wide with about 4" of loft. There is no tag on the bag, but I would guess that it is warm down to around 30 degrees f. It is fully rectangular and can be zipped completely open to be used as a quilt.
