Abstract
An insulated sleeping bag insert constructed such that when used with a sleeping bag provides additional insulation thickness above and to the sides of the user, thereby extending the lower limit of the usable temperature range of the sleeping bag. The insert is fitted with attachment mechanisms that allow it to be attached and retained in position within the interior of the sleeping bag. The insulated sleeping bag insert construction is unique in that, in addition to a layer of uniform insulation over the sleeper's body, additional insulation-containing space fillers are incorporated into the sides of the insert to fill-in around the sleeper for reducing the internal volume of the bag.
