Some use the thermarest pads. Either the inflatables or the Ridgerest. The best inflatables that I can see are the Exped ones which have down in them. They'll take you to some low temps. You'd still probably need some side protection as they are usually only 20" wide. Although they have some 26" wide. Many use the Wal-Mart pads such as the 3/8" thick blue pad. It is cheap and very popular.
