How Many Grams Of Down in General Down Jacket

Generally, the filling amount of outdoor down jacket is about 250-450g according to the target design. According to the provisions of the national standard for down clothing (GB/T14272-2002), the down content of down clothing shall not be less than 50%, but there is no lower limit for the down filling of each down clothing. In the south, generally, the down filling amount of adult down clothing should be at least 100 grams in order to have the warm effect of down clothing.
The characteristics of down filling structure determine the warm and lightweight characteristics of down jacket. It is very difficult for down to have fiber stiffening, so when the down is surrounded by the fabric, it will form a small space with a three-dimensional box-like structure and a double-layer clip structure, which is also known as the fluffy structure.
For the three-dimensional box structure, its advantages are that the down is evenly distributed and there is no cold bridge effect, but the manufacturing process is complex, and the weight of down clothing will also be greatly increased; The advantage of the double-layer clip structure is that the weight of the clothes is light, but there is a lack of down at the sewing position, which is easy to be blown through by the wind, so it is generally used in the inner down jacket.
The smaller the structure space of a down jacket is, the more the amount of down filling or the more uniform the distribution of down is. However, various structures have certain advantages and disadvantages, so different structures are suitable for down jackets with different wearing methods.
