Abstract
Abstract A sheet liner for a sleeping bag or the like which can be easily removed from the sleeping bag for washing. The liner is formed from a single sheet which is folded crosswise to form top and bottom panels having a lower fold. The panels are joined along their side edges by seams extending from the lower fold along a major portion of the side edges but terminating short of the upper edge of the top panel. The bottom panel extends beyond the top panel, forming an end margin for a pillow when the liner is inserted into the sleeping bag.
