You will find out who has the shittiest bag at hunting camp. They will be up feeding the stove st night. mtmuleyI am another one in the no heat after lights out needed. We dampen the wood stove down as low as possible right before bed and then fire it up first thing in the morning. I use a big 4" pad, a -30 ve Browning sleeping bag (cheap and bulky but waaaarm) and a Montana Canvas bed roll. I have been in that set up down to -15 and have never been chilly. Sleep system is definitely where to address warmth.
