I have an older TravaSak down sleep system. The velcro in sheet is missing, but the bag is still in excellent condition. The TravaSak, for those who don't know, was a down sleeping bag with one side filled less than the other. So one side was for summer and one side was for winter. I don't know if it is goose down or duck, or the fill quantity. What I do know is that is was pretty spendy back when I bought it, and very comfortable and warm. Zipped together it measures 60 inches wide and 72 inches long. Either side would make a good individual quilt or bag. If some one want's it I will let it go for $100 $90 $75 $60 plus actual shipping??
