What is the standard for the fluffiness of adult Down Jackets?

According to the latest national standard GB/T 14272-2021 "Down Clothing", the fluffiness standard for adult down jackets is as follows:
Adult down jackets: Fluffiness must reach 450 cubic centimeters/30 grams.
This standard ensures the basic requirements for down jackets in terms of thermal insulation performance. The higher the fluffiness, the better the thermal insulation performance of The Down Jacket. For example, the fluffiness range of common down jackets on the market is as follows:
550-600 FP: suitable for daily wear, with good thermal insulation performance.
600-700 FP: suitable for colder outdoor environments, with excellent thermal insulation performance.
700 FP and above: high-end products with excellent thermal insulation performance.
In addition, the fluffiness test method has also been updated. According to the GB/T 14272-2021 standard, the fluffiness test method has been changed from the original oven reduction method to the steam reduction method, and the test conditions are more stringent. This makes the test results more accurate and in line with international standards.
When purchasing down jackets, it is recommended to check the fluffiness mark on the product label and combine it with other indicators such as down content and filling volume to ensure that you buy A Down Jacket with excellent warmth retention performance.
