Using 100% soft organic cotton, the fabric is incredibly breathable and moisture-wicking, keeping you dry and cool during the whole night. Out organic cotton is ethically grown, ensuring and keeping its natural feeling. The duvet is filled with white feather fiber and down, with an extra step to remove solid feather quils, providing plushness and softness. Designed with sewn-through construction to ensure uniform distribution of the duvet filling, and avoid shifting or bunching. The comforter can be anchored to a duvet cover by its four convenient corner tabs.
