Number one is to have enough fuel in you. Eat and drink enough. I find high carb meals don't keep me warm, buts it up to you to experiment with what foods keep you warm. Second most important, don't get cold before you go to bed. Don't start out cold and thinking you'll warm up once in your bag, hat and gloves, down jacket around camp. Then next would be ground insulation, have a good sleeping pad, the cold ground can suck all the heat out of your bag. The warmth of you bag is one of the last things I'd consider important, but definitely if your sleeping cold, get a thicker bag.
I've slept in -35 on an ice climbing trip to the Rockies and was warm all night. But I slept in my clothes, with two sleeping bags and double sleeping pads. Whatever it takes for the conditions.
The greatest signature ever, tribute.
