Is the lightweight down jacket warm
Lightweight down jackets have less down content, so they are not as warm as regular down jackets. Lightweight down jackets have the advantages of being lightweight, soft, and innovative in style. However, due to the relatively small amount of filling, their thermal insulation performance is more suitable for wearing in early winter or when it is warm and still cold, and is not very suitable for the cold season of deep winter, especially in the north.
The principle of keeping warm in down jackets
China already has a national standard for down clothing, which elaborates on the concepts of down clothing such as down content and filling capacity. At the same time, it is stipulated that the down content of down clothing must reach 50% or more. The testing of down content, down content, fluffiness, cleanliness, oxygen consumption, and odor is the core item for evaluating the quality of down. The amount of down content affects the warmth retention of down clothing.
The difference between velvet content and filling velvet content
Simply put, the filling amount refers to the total weight of down and plush, measured in grams; And the down content is the proportion of down to the full down content. For example, if a down jacket with a filling capacity of 100 grams has a down content of 90%, it indicates that the down content is very high, with 90% down and the other 10% down, which is feathers.
