The Fossflakes Duvet drapes effortlessly around your body while you sleep and keeps a comfortable temperature throughout the night.

Temperature regulating properties ensure that the duvet stays warm, but not unpleasantly so.

The filling is a blend of small, light Fossflakes and polyester ball fibres. This blend ensures a duvet that retains its volume year after year.

The ticking is made of 100% cotton cambric with tightly woven, smooth surface.

Machine wash at 60°C. Get an even better result by tumble drying the duvet at low heat (max. 60°C). The filling stays evenly distributed and does not get lumpy, even after frequent wash and use.

Both filling and ticking is certified after the strictest Standard 100 by OEKO-TEX.



The Fossflakes Duvet filling material is a unique blend of 70% Fossflakes Essential (polyethylene) and 30% Fossflakes Clusters (siliconized polyester fibers). A blend that makes the duvets soft, yet durable and long lasting. Thanks to its design, the unique and patented filling material distributes itself evenly, is always re-fluffable and will not form lumps after use or wash.
