For colder weather, I take my Exped 7 Down air mattress.
One of the best investments I've made. I caught it on sale at Moosejaw for about 50% off.

I've used the blue ccf but prefer the Exped.

My son uses the blue ccf and is fine with it.

We are both using Claytor's now so the double layer helps with being able to move a little easier.
