Intelligent design inspired by Swiss practicality - the GENEVA Four Seasons white goose down duvet consists of 2 quilts, each with different warmth retention capacity. Christian Fischbacher's European comforter is designed to be used separately (1 summer duvet + 1 spring/fall duvet) or snapped together for a cozy, comfortable winter duvet. How's that for Swiss ingenuity? For additional white goose down duvets, please see Christian Fischbacher Down Comforters and see our latest Gstaad Down Pillow an adjustable dual-chamber down pillow, also by Christian Fischbacher. To maintain your European goose down duvet, we recommend a duvet cover. Please refer to Christian Fischbacher European Linens homepage for a selection that includes solid sateen, vibrant prints, cotton jersey knit and 100% linen.
