This is a Snow Peak down sleeping bag. It is not synthetic. There are no scratches, noticeable stains, or odors on the sleeping bag itself, but the storage case has a tear (see photo). However, there are no particular problems with its use. It's perfect for the coming season. We have inspected the item, but as it is a used outdoor product, please refrain from purchasing if you are looking for a perfect item. NANGA Sleeping bag Down sleeping bag
