I've come to the conclusion that winter camping for me will no longer happen as I have too many winter activities going on. So my loss is your gain.
I have a NEVER USED outdoors 0* full length incubator. I bought it, set it up inside to check fitment/comfort. I then put it in the storage bag (uncompressed) and it has sat there for over a year in my gear closet. Comes with storage bag pictured, and stuff sack.
