I’ve found with my Big Agnes air core mattress I need thermal break between me and the mattress or it will suck the heat right outta you. A cheap foam pad does wonders.
If you don’t use a air mattress, I’ve also had good luck with a 2” foam pad, a quilt draped over the cot so cold air doesn’t get underneath. Then your sleeping bag on top.
Believe me, I’ve been so cold by not having the right system.
