Down content refers to the percentage of down and down fibers in the total amount of feathers and feathers used to fill a garment. For example, if you buy a down jacket filled with 90% white duck down and 10% white feathers, it means the down content is 90%.
When deciding to buy a down jacket, always check the product label on the collar. Be wary of jackets with a down content below 50%, as they do not meet the minimum standards for down clothing stipulated by national regulations.
