hmmm ...maybe I read your OP incorrectly... not sure I understand what you are asking.

During warm seasons were you may not need any insulation you can just bring a light fleece blanket. Of course you need to be careful you are not caught out with temperatures dipping lower than expected. For that reason, I typically bring my quilt anyway. If it is a bit too warm I will stick a leg or arm out. This is pretty similar to how I regulate my body temperature at home (where it rarely gets very cold at night smile ). Does that answer your question?
