High-quality down and feathers

Under a duvet, one can sleep both in winter and spring, in the plains and high mountains, and always be perfectly comfortable. It is precisely this crucial function of thermoregulation that enables birds in general, and geese and ducks in particular, to withstand temperature fluctuations of 60°C (-20°C to +40°C) without ever changing clothes. The thermal insulation power of a duck or goose down flake exceeds that of sheep's wool by 80% and that of synthetic fibre wadding by more than 100%. Consequently, for the same thermal insulation, a quality pure down duvet weighs 2 to 3 times less than a wool or synthetic fibre cover. Thus, sleeping under a duvet, the feeling of wellbeing and physiological comfort reach very high levels.

Since with imports, especially from China and Asian countries, there is no specific legislation on the subject, it is possible to come across products that are called "down", but which in reality are not and above all do not have these characteristics. More and more often chicken feathers, mixed with a few down, are used for fillings that bear the undeserved label of down.
