Good points.
Sleeping bags:
A 30 deg sleeping bag and light summer bag/insert covers you from 20 deg F to 75 deg where you might sleep on the bag (not in).
Inserts are as cheap as $20 fleece. The wool or silk are warmer but cost more.
Do not use the blowup air mattress/pads for in cold whether. It will cool you and not hold your heat.
Mummy bags are not for everyone. I like the rectangle and my arms to be out. However the mummy bag covers you well. Be sure to check the size. Like clothes there are men’s and women’s sizes and extra ling or 2xl... then various deg bags.
Children’s theme/Disney bags are for basement/TV/living room camping. They do not provide proper insulation for cold weather camping.
You will note better winter bags have more than one layer of insulation. They are not sown through from outside to inside. And they have a Velcro flap over the zipper if it has a zipper at all. All of these things let cold air in.
Lastly take one big woolen blanket to cover everyone.
Those silver survival blankets that come in a little pouch do really reflect warmth back to your body.
Other:
Don’t pull your head inside the bag. Condensation of your breath wets the bag. A wet bag looses its thermal capability.
Keep wet stuff outside the tent.
Typically in the winter the cold air is much dryer and aids drying out wet things.
Boots and socks and old wet clothes hung outside to dry.
After a night sleep let the tent air out so moisture doesn’t build up.
Turn your bag inside out to air while eating breakfast.
Examples of bag sewing and zipper.the one with all the stitching is a $30 40 deg F bag and the other a $300 zero deg F bag. The black one you will note the stitching going in opposite directions inside vs the outside.
