Yves Delorme uses top-grade white European goose down to provide loft for insulation and lightness for freedom and comfort. Encased in the finest quality batiste, these comforters combine modern technology and beautiful craftsmanship. Yves Delorme uses hand-selected mature white European goose down from free-range geese. The down is gathered during the molting season when it has reached its full size and potential to hold air. The loose down is not plucked but rather collected as the geese are molting.
