ABSTRACT:
A thermally insulated down-fill fabric of reduced thickness and having a down-fill composition. A patterned envelope is formed and defines a pouch in which down or a down-fill composition is inserted and distributed substantially evenly within the envelope. The envelope is then compressed and stitch seams are formed to define a quilt pattern of closely spaced stitch lines to reduce the loft of the down-fill composition by about twice the normal loft thereof. This procedure is repeated over the entire envelope whereby the fabric has at least half the thickness of the normal loft of the down-fill composition.
