The down in the Salzburg duvet is one of our most distinctive downs because it looks and behaves like a "White Eiderdown". It is meticulously hand sorted to obtain the largest clusters with the highest densities and cling factor possible. While down tests show an 800 loft, its Eider-like properties give it the equivalent insulating power of a 900 loft. This down is incredibly soft and lightweight, and lasts for generations.
