Nothing adds a layer of comfort to your bed like a duck down-filled duvet cover. This all-year round cover lets you sleep in restful luxury whatever the season. The Comfort Lock construction holds more down on top of the bed where it is needed with less falling to the sides and bottom while the diamond box quilting helps keep the down from shifting.
