The down content is the ratio of down to down, usually expressed as a percentage. According to the national standards of down jackets in China, the cashmere content of down jackets should not be less than 50%. According to this standard, no matter how heavy down jackets are, as long as the cashmere content reaches more than half, they are qualified down jackets.
However, the cashmere content is different from the cashmere filling amount, which refers to the weight of all down filled in down jackets. Under the condition of ensuring the cashmere content, the cashmere filling amount of adult down jackets in the south should be more than100g, and that in the north should be more than 200g, so that down jackets can play a better warm-keeping effect.
The most common fillers in down jackets are goose down and duck down, which can be divided into white down and gray down according to color. According to the price, the down jackets in the market are ranked as grey duck down with white goose down, gray goose down and white duck down. It may be affected by the ranking of selling prices, so many people think that these cashmere are also ranked in this way in quality, but it is not. Through the theoretical research and practical experience of down, generally speaking, goose down with the same quality and down content is better than duck down in warmth and bulkiness, but the color has little to do with the quality of down jacket.
