A self-inflating thermal mat. Great for use inside a tent. Very light weight and easy to carry along when folded. When opened the mat inflates itself automatically to a thickness of about 2 centimeters.
A word of warning - the mat is relatively thin but still much better than nothing, and with the even weight distribution of a sleeping person provides good insulation from the ground.
