![]() ![]() Tip: The higher the cuin value, the higher the fill power, the better the insulation. One cuin corresponds to around 16 cubic centimeters. Then the volume to which the material expands after compression is measured. To determine how much cuin a material has, one ounce (about 28.35 g) of insulation material is compressed for 24 hours. A high fill power ensures better insulation. The fill power describes the ability of the down after compression to come back to their original, bulky form. You want to buy a down jacket or a down sleeping bag? Then you should pay attention to the following aspects, which give you hints on the quality and insulation capacity of the down. What you should consider when buying down products ![]() In the long run, however, the price difference becomes less important: down products are much more durable than synthetic fiber products. High-quality down, which come from fair animal husbandry, are available only in limited quantities. For this reason, down products often have high prices compared to synthetic fiber products. Since the duck species is under protection, the animals must not be plucked. The downs are instead collected by hand from the nests of the animals – of course, after the end of the breeding season. A huge effort! No surprise then that you will rarely find the eiderdown and if so, then for lots of money – a good keyword: how much does a “normal” down product actually cost? Price The absolute super-down (the finest, lightest… and by far the most expensive) comes from the eider duck. ![]() Geese down are a bit higher quality because they isolate better. The fillings used are the down of geese or ducks. If the soft feathers get wet, they lump, lose their three-dimensional structure and thus their ability to isolate. The down does not break but takes a long time to dry again compared to synthetic fibers.ĭue to their natural properties, down are almost perfect fillers for jackets, bedding and sleeping bags. However, there are some criticisms regarding the procurement of down.ĭown is relatively sensitive to moisture and wetness. Provided the right care, down (products) are very durable.įeathers are products of nature and therefore ecologically harmless. With this design, the down can store much more air and can, therefore, isolate better. Unlike traditional feathers, down is three-dimensional. The small feather branches are arranged on the feather keel radiate in all directions. Down is extremely elastic – (nearly) no matter how much you compress down, they quickly unfold and find their way back to their original shape.ĭown is a real leader in terms of weight – no other feather is that light. ![]()
