Couples Dual Warmth 80% Duck DownPerfect for couples with varying temperature preferences, one half of the quilt is warmer than the other, eliminating the need for separate quilts. The cassette style ensures even warmth distribution through individually filled squares. With 80% duck down and 20% duck feather, this quilt offers a higher ratio of down clusters, providing a light and lofty feel that's superior to quilts filled solely with feathers.
