Abstract
An article of bedding, such as a sleeping bag, is constructed so as to allow a user to selectively and alternatively control the insulating properties of the covering structure over the user's feet. Specifically, the lower portion of a main cover layer of a blanket or main sleeping bag cover is provided with an overlying top covering layer. Also, a slit is defined transversely across the lower portion of the main covering layer between about one foot and about three feet from the foot extremities of the blanketing layers. The user selectively inserts his or her feet either beneath both covering layers, or through the slit in the main covering layer. When the user's feet are inserted through the slit, they are covered only by the top covering layer below the slit. Preferably, the foot extremities of the top covering layer and the main covering layer are provided with an open-mesh ventilating panel therebetween. This permits air circulation in between the lower portion of the main cover layer and the overlying top cover layer to prevent the user's feet from becoming too warm. The foot extremities of the main cover layer and top covering layer may be releasably secured to the other by a zipper or some other releaseable closure device.
