A vintage one owner Jansport mummy bag with goose-down top and hollow-fill bottom(Polar-Guard) rated to 30 below zero. Bag has only been used about 6 times. If you need a bag for cold weather camping, or hunting in sub-zero weather, this bag is second to none, as the hollow-fill bottom makes all the difference when compressed. If your looking for a cold weather backpacking bag, look elsewhere, a bit too heavy and doesn’t compress small due to the synthetic bottom. Bag has one patch sewn on by Jansport, back when you could walk into their Pain Field repair center. Always stored in a large breathable cotton bag. A great bag if you need the warmth. Bag weighs about 5.75 pounds.
