850 Fill Power Canadian White Down Duvet Insert by Peacock Alley
This duvet insert encloses highly lofted Canadian white down in a smooth cotton sateen casing. A baffle-box construction distributes the fill to maintain an even, comforting layer.
Corner loops allow the insert to be attached within a separately purchased duvet cover, while Queen and King sizes differ in both proportions and fill weight. It is a practical warming layer rather than a decorative outer duvet.
“I prefer a duvet that offers warmth without feeling cumbersome. Fine down has a particularly welcome lightness when the room is cool. The carefully divided baffles are a useful detail because they help the bedding remain evenly comfortable.”
-Mrs. Mayfair
