Promenade is the must have down alternative all season duvet insert. The comforter features a 100 percent cotton cover with 1 inch baffle box 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.
