The Kaiser duvet is filled with premium white Masurian goose down. This high-quality down is light, fluffy and springy. It has outstanding gap-filling capacity and preserves warmth like no other. The fluff clusters are quite large with FP 750, which is considered high quality. This warm winter model could be used all year round as well. The duvet is produced in Germany. The Kaiser model quality is confirmed by European certificates: Oekotex, Finest Down, SanProCare, Bramscher Tuch. The cover is made of snow-white high-density (300 TC) cotton nanobatiste. This dense fabric securely holds even the tiniest fluffs inside. The cotton textiles are moisture-absorbing, breathable and do not accumulate static electricity. A cassette quilting prevents the deformation of the duvet prolonging its durability.
