The Down and Feather 3-Chamber Pillows are composed of three internal chambers. The center chamber is filled with feathers for support and to determine the weight of the pillow. Outside chambers encase the center chamber with goose down for softness. 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.
