I'm looking for a double sized liner. The dimensions say 80x68, is this one flat sheet or the size of the liner as a bag? I have two retangular Kelty sleeping bags that my husband and I have zippered together, making it a double. We would like to find a double sized liner, top and bottom, to fit inside. The idea being that we can wash the sheets easier than the bags. Thanks!
