Step four. Shovel snow onto the roof tarp. Pack down. This insulates your lodge. I placed multiple layers underneath my expedition -35c sleeping bag. I usually use a second bag inside the winter bag. I like to be cozy. Underneath is a reflective foil blanket, a closed cell foam r4 pad with a thermal estate 2.5" closed cell foam self-inflating mat.
