Abstract
Abstract A sleeping bag is made of a fabric consisting of a thin and flexible material impermeable to water, at least one side of the fabric being metallically shiny. The bag can be closed by a drawband provided at its opening. A strong strip of webbing is attached centrally to an outer surface of the bag and extends in its longitudinal direction. Spaced transverse bands are attached to the strip and to the fabric. Their ends are provided with loops, so that two rows of loops are formed. The loops may be used for carrying the bag.
