Grey duck down content of down jacket is 90%, cashmere filler 124g, and the length is 89cm. Can I wear it from -20 to-10 degrees?

Yes, but I suggest wearing more clothes inside.

The cashmere content and filling amount are the key to determine the quality of down jackets. The cashmere content is generally above 70%, which has a certain fluffy and moist feeling. Cashmere filling quantity is related to the warmth of down jacket, which should be determined according to your own needs. ?

High-grade down jackets generally use more than 90% white goose down or more than 90% white duck down. More than 90% down jackets are warm and fluffy, and they are light and comfortable to wear. Generally, the down jacket contains 90% down and the down filling amount is 230g~320g (depending on the size of the goods), so as to adapt to the environment of minus 20 ~ minus 30 degrees in the north.

Generally, the cashmere content of outdoor down jackets is about 250 g to 450 g depending on the target design, and the cashmere content is generally above 80%. This data shows that cashmere content is 80% and feathers account for 20%.

Generally speaking, take a long down jacket with a cashmere content of 90% as an example. If you are used to wearing only a thermal underwear or shirt, and take the outdoor environment at about 0℃ in winter in the north as an example, it is recommended to choose a cashmere-filled style above180g.
