I was in a -20F bag at a very windy ~35F and didn't get much sleep at all. Actually, because it was a bag system and how I used it, it had much more insulation below me than a normal -20F bag and I was still cold through the bottom.
If it weren't windy that night I probably would have been ok...but on the trail you can't guarantee those conditions. Much better to have a bag or quilt rated to conditions, and an accompanying plan for bottom insulation rated to conditions. A pad, underquilt, etc.
“Republics are created by the virtue, public spirit, and intelligence of the citizens. They fall when the wise are banished from the public councils because they dare to be honest, and the profligate are rewarded because they flatter the people, in order to betray them.” ~Judge Joseph Story
