<p>A sleeping bag (10) having a plurality of superposed bags (14,16), one within the other, the number of superposed bags depending on the degree of thermal protection desired. Besides having an opening (18) to expose a user's face, each bag has an open side, closable by a slide fastener (22), to facilitate entering or exiting the sleeping bag. Disposed along and proximate both sides of the slide fastener of each bag are two rows of non-slide-type fasteners (34) having top and bottom engagement surfaces secured to the outer and inner surfaces of each bag. The non-slide-type fasteners can be used either for selectively attaching an inner bag (16) to an outer bag (14) or for closing the open side in the event that the corresponding slide-type fastener fails to operate. A weather-resistant shell (12) may also be selectively attached to the outer bag for additional protection.</p> |
