This year round comforter is filled with lofty large cluster Hungarian white goose down from mature geese making it perfect for all seasons. Calla Lilly's premium 750 + fill power creates better loft and insulation and helps maintain a comfortable body temperature without adding extra weight. White goose down has a three-dimensional structure that traps air for warmth, yet allows perspiration to dissipate, for unsurpassed comfort. To give the comforter an even more luxurious feel, it is covered with 310 thread count 100% Egyptian-Quality Cotton from Austria. 10" baffle box construction keeps down evenly distributed while allowing maximum loft and edges are finished with double stitched piping. If cared for properly, this comforter will last for years, and in time, it will be considered a valuable heirloom in your family's treasure chest. Hypoallergenic due to DownTown Co.'s stringent cleaning processes that remove dust, dirt and other allergens and the superior quality of down used. Wash with care but not too often.
