Feature:
Made of original 18-count polyester-cotton blended fabric (genuine synchronized fabric)
International standard 80% white duck down
Analytical properties of materials:
The original/polyester-cotton fabric has a high polyester fiber content, and the polyester-cotton fabric has high heat and light resistance and good stability. It has bright colors, high fiber strength, durability, light resistance, heat resistance, and straightness. As we all know, the original version uses 80% white duck down. The fill power refers to the cubic inches of volume occupied by each ounce (30 grams) of down under certain conditions. If one ounce of down occupies 500 cubic inches, the fill power of the down is 500. So we can simply understand it as: fill power is the volume of down, and the volume of down is fill power. The higher the fill power of down, it means that under the same filling amount, down can fix a larger volume of air layer to keep warm and insulate, so the warmth retention of down is better.
