Finished in a feather-proof cover, with a square cassette/box construction to ensuring that the feathers stay in place while the cloth walls eradicate cold spots. The feathers help to added weight to the duvet so that it lightly molds itself to the body to keep you warm and snug all night long. 100% Microfibre cover finish, for comfort, breathability and also makes it suitable for people who suffer from house dust allergies. While the feather and down have been specially chosen for their high thermal qualities, all-natural duvets contain fillings that have been washed, sterilized and steam purified to the European Feather & Down Association’s highest standards making them hypoallergenic.
