Setup is just a thin rain mat, tent, sleeping bag, and inside dressed mostly in wool. If traveling with a parka and it's clean/dry, I might wear it inside but suppose it could be laid underneath as a pad. With colder but not sever temperatures coming up I might give that a try and see what difference it makes.
