90 % goose down / 10 % goose feather. The more down, the lighter the feel; 180 g/m²+ 100 g/m². Optimum breathability, soft and light, warm and ecological. The Downafresh Greenline label is only awarded to manufacturers who do not use feathers or down from live animals and can stand over the welfare of the animals. Feathers and down have been sterilised at 120°C. Cover made from 100 % “soft finish” percale cotton, finished with satin piping. The closely woven anti-feather cover not only prevents feathers and down getting through but also offers you added protection against dust mites, which is what the Nomite label stands for. The duvet is made up of 2 detachable parts that clip together: the summer part + spring/autumn part clipped together give you your winter duvet.
