Our air runs at 70 in the winter and 75 in the summer to help keep the electric and gas bills under control. My kids pretty much wore Carter's fleece footie jammies or Children's place cotton footie jammies with socks until they were 5 because they accomplished 3 things: 1, kept moisture in; 2, kept an extra layer on their feet, and 3, kept them from scratching.
Now that my oldest has gotten too big for footie jammies (although he does have a couple of them), he mostly wears fleece pants with an undershirt and socks to bed. I generally take one of the kids shopping with me and have them run their hands on things I am thinking about buying.
If it catches on their cracks, like most polyester does, I can't buy it. A lot of the Disney pjs are that icky polyester material. Finding cotton is a lot harder, but I generally find it or an acceptable blend if I don't look at licensed character options.
