Kidney belt modifying part for a stretchable kidney belt

The invention relates to a part (Fig. 1) which is predominantly made of leather, synthetic leather and lining fabric and can be pulled over a stretchable kidney belt (Fig. 2). Such a part is of great practical interest because it enables the owners of stretchable kidney belts to modify their thin summer kidney belt for the cooler months of the year by simply pulling over the part described above (using the open ends of the remodifying part Fig. 1 opening a.) and b.)) to form an all-weather kidney belt without having to buy in addition an appropriately lined kidney belt for the cooler months of the year. According to the invention, a back part which is open on both ends and is predominantly made of leather or synthetic leather (Fig. 1) is pulled over the stretchable kidney belt (Fig. 2), so that the kidney region of the wearer is covered by the modifying part.
