The Nobilis duvet is filled with 100% premium white Austrian goose down. The down of geese, grown in the natural environment at the foothills of the Upper Austrian Alps, is softer and fluffier and perfectly restores its original volume after squeezing. The fluff clusters are quite large with FP 800, which is considered the highest quality. The duvet filled with such down is very warm and comfortable. Only a few hundred of such duvets are produced in a year, which makes every one of them unique. All duvets filled with this precious down are handmade at every stage of the production. They all are hand-filled with the down that has been cleaned and sorted several times. A cassette quilting prevents the deformation of the duvet prolonging its durability. The cover is made of snow-white high-density (380 TC) cotton mako-batiste. This dense fabric securely holds even the tiniest fluffs inside. The cotton textiles are moisture-absorbing, breathable and do not accumulate static electricity. Such cover provides the longer durability for the duvet.
