How is the quality of down jacket? How to tell?

1, smell the down jacket. If you find pungent or smelly, just ignore it. It has been explained that goose down is more expensive than duck down because goose down is tasteless, while duck down smells. But as I said before, duck down and goose down are processed in the same way. Delicious down (whether goose down or duck down) belongs to unqualified products and must not be bought. 2. Check whether the basic information indicated on the down jacket sign is complete, mainly including cashmere content, cashmere filling amount, cashmere type and basic information of the manufacturer, but generally excluding cashmere information. You can consult the shopping guide directly. 3. Touch the inner layer of down jacket carefully. If you feel prickly, it means that this dress has a high feather content (see the concept of "down" above for specific reasons) and the quality should not be very good. If you don't prick your hand or prick your hand, it means that this dress has a high cashmere content and good warmth retention. Next, you can put several fancy down jackets together and press the surface of the clothes with the same strength. The faster the rebound time, the better the quality of down jacket (indicating high bulkiness). For down jackets with the same cashmere content, the larger the volume (that is, the fluffy the down jacket), the better the quality. 5. Finally, pat the down jacket hard. If there is fluff or dust, it means that the fabric of this down jacket has poor cashmere resistance or the stitches are too big, so the down jacket will become thinner and thinner, and the waterproof and breathability will not be too good. For this kind, it is not recommended to buy.
