Whether the amount of down jacket can be filled is small depends on the type and design of down jacket. Generally speaking, the common down jackets on the market are divided into two types:
1. Filling down jacket: This kind of down jacket is filled with down, common goose down and duck down. When the volume of filled down jacket is small, you can try to increase the volume by filling the pile or manually. However, it should be noted that the uniform distribution of stuffing should be ensured when filling, so as not to affect the thermal performance and comfort of the down jacket.
2. Viscose fiber down jacket: This type of down jacket uses viscose fiber (artificial velvet) as a warm material. Because the thermal performance of viscose fiber down jacket mainly depends on the density and thickness of the fiber, it should not be filled after purchase. Filling too much artificial wool may make the down jacket too heavy and affect the comfort of wearing.
In short, after purchasing a down jacket, you can try filling it according to the type of clothing and needs. However, pay attention to the uniformity and thermal performance of the filling, so as not to affect the use of the down jacket. At the time of purchase, you can also ask the sales staff for relevant suggestions on filling. At the same time, choose regular channels to buy down jackets to ensure product quality.
