<p>A sleeping bag having a plurality of superposed bags, one within the other, the number of superposed bags depending on the degree of thermal protection desired. Besides having an opening to expose a user's face, each bag has an open side, closable by a slide fastener, 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 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 to an outer bag or for closing the open side in the event that the corresponding slide-type fastener fails to operate. A weather-resistant shell may also be selectively attached to the outer bag for additional protection.</p> |
