Queen size Washington comforter is filled with 37 oz of a mix of white duck and goose Down. This Down comforter is filled with a mix of white duck and goose Down, taken from birds living in northern states, with freezing temperatures during the winter. Ducks and geese have naturally developed a Down of quality that keeps their organs warm during the winter. It is this Down that fills your Washington comforter. A duvet shell of 264 thread count will prevent the comforter from leaking. The 100% Downproof cotton fabric, in a baffle box construction, will bring you the softness you need for the comfort of your nights. This comforter made with quality components gives you one of the best loft power in the world! The Down will expand at its highest (575+ cu.in/oz) especially in a cool room. You just have to shake your comforter and it will have its original shape back. This comforter is ideal for those who are looking for warmth and lightness in a cold region of America. We recommend the use of a comforter cover which will ensure the protection of your Down comforter..
