Choosing down jacket science:
1. smell the down jacket. If it is pungent or smelly, it means it is not good. Some people explain that goose down is more expensive than duck down because goose down is tasteless and duck down has taste. Delicious duck down (whether goose down or duck down) is an unqualified product, so don't buy it.
2. See if the basic information marked on the down jacket logo is complete, mainly including cashmere content, cashmere content, cashmere type and basic information of the manufacturer, but generally not including lightness information. You can consult the shopping guide directly.
3. Touch the inner layer of down jacket carefully. If there is a tingling sensation, it means that the feather content in the down jacket is high (see the concept of "down jacket" above for specific reasons), and the quality should not be very good. If you don't feel the thorns, it means that the cashmere content of the clothes is relatively high and the warmth is better.
Next, you can put your favorite down jackets together and press them on the surface of the clothes with the same force. The faster the rebound time, the better the quality of down jacket (indicating that the down jacket has high bulkiness). The same number of down jackets, the larger the volume (that is, fluffy down jackets), the better the quality.
5. Finally, take a down jacket. If there is fluff or dust, it means that the down jacket fabric has poor down resistance or too large stitches.
