Promenade is the must-have down alternative all-season duvet insert! The comforter features a 100% cotton cover with 1" bafflebox construction allowing for an even distribution of the hypoallergenic cluster fiber microfiber fill. Piped edges add a touch of classic style to this otherwise understated design. The larger size of the comforter fits larger premium mattresses. To keep clean, we recommend spot cleaning any stains or spills.
