According to the latest national standard GB/T 14272-2021 "Down Clothing", the down content of down jackets shall not be less than 50%.
(II) The effect of down content on thermal insulation
The higher the down content, the better the thermal insulation performance of The Down Jacket. For example:
90% down content: suitable for extremely cold weather and long-term outdoor activities.
80%-89% down content: suitable for cold weather and daily outdoor activities.
70%-79% down content: suitable for general cold weather.
60%-69% down content: suitable for warmer weather.
