The Finning Duo Duvet is our most flexible and versatile bedding staple. Consisting of two separate duvet layers of varying thicknesses, the duo-duvet can be changed to use through the year. Each layer is made of a very lightweight goose down with 10% feathers for soft, lightweight comfort. The summer layer is super light, suitable for hot nights, while the second layer is slightly heavier, perfect for using in transitional seasons. The layers can also be buttoned together to create one super warm, fluffy, breathable layer for winter. Both duvets are finished with a narrow flange hosting the buttonholes and neat sateen piping. The duvet comes with a zippered dust bag, perfect for storing the layer that's not on the bed.
