Are you looking for advice/answers or promoting Aerogel?
In winter I use two lightweight sleeping bags one inside the other. With that setup I can use one of the sleeping bags in warmer weather thereby cutting down on needing space to store multiple season dedicated sleeping bags. I often winter camp with just a tent fly set up on about a 45 degree angle over the area I'm sleeping on. I can see the stars and critters that way.
