Abstract
A sleeping bag includes a non-expansible, sleeve-like upper sleeping bag segment, a non-expansible, pocket-like lower sleeping bag segment and an outwardly expansible, sleeve-like intermediate sleeping bag segment. Together the sleeping bag segments form a sleeping bag inner chamber. Resilient bands of elastic material are located at the intermediate sleeping bag segment to maintain the intermediate sleeping bag segment in a condition which will not constrict or lessen the cross-sectional area of the bag inner chamber when the intermediate sleeping bag segment is in unexpanded condition.
