Goose or duck down filling?
If you compare downs from duck with geese of the same mature age, you will see that the goose down (goose clusters) are bigger than duck cluster (ducks are smaller than geese).
Goose clusters have plenty of elastic resistant filaments, which, when they interlock form millions of tiny air pockets and thus provide heat isolation. As duck clusters have less filaments, (less isolation capacity) the duck down filling must be + 30% heavier to obtain the same isolation capacity. Goose down has little or no odour. Duck down has a stronger odour, so initially it has to be washed with stronger detergent which weakens the duck down structure and thus makes the duvet less durable. Different breathe- ability / isolation function. When you put yourself under a high quality goose down duvet you will obtain your own cosy body temperature in a few minutes – while with duck filling it takes longer. Ducks are an important part of Asian stable food so there is plenty of industrialized duck farming in contrast to the few remaining goose farms. Goose down duvets are lighter, last much longer and offers your better body transpiration.
Danimarca s.r.l. Piumini Danesi® pooq dene® only use big soft down clusters from the breast and neck of mature geese for their duvet fillings. Lightness, volume, compressibility, elasticity, softness, isolation, transpiration and durability are characteristic of our filling.
Down or Feather from water fowls?
Only down from water fowls have the benefit of being durable, naturally breathable and insulating to keep you warm in winter and cool in summer. With feathers from land fowls, you can only add weight, as they have poor insulating capacity.
‘Down', the lightest of all fillings, refers to the soft, light clusters found under the feathers of ducks and geese. The down of the bird does not contain feather quills, but is luxuriously soft and fluffy and contains thousands of tiny air pockets which offer excellent natural insulation – keeping cold air out and warm air in. It is, after all, these clusters which provide the insulation to keep geese warm in really cold temperatures and enables them to swim in freezing waters.
Feathers, which contain quills and are flat for streamlined flight and swimming, are much firmer than down. Nor are feathers as soft and light as down. Basically with poor insulation qualities.
The higher the down content, the lighter, better quality and more durable the product will be. Down filled duvets should last for at least 20 years. The durability of fillings containing feathers is proportional to the feather content.
+ Down clusters = + lightness + softness + insulation.
+ Feathers = + weight, minus insulation, minus durability.
Danimarca s.r.l. Piumini Danesi® pooq dene® only use NEW raw material, subject to strict controls throughout the manufacturing process from the Danich and European authorities.
