Cotton-padded clothes generally have three components, which will be marked separately, such as:

Fabric: cotton 35%+ polyester 65%, or cotton: polyester = 35: 65.

Lining: 100% polyester fiber.

Filler: 100% polyester fiber

You didn't write that thing in front, and you don't know whether it refers to fabric, lining or filler.

Generally speaking, cotton is more expensive than polyester, and more cotton is also more expensive. However, the quality of clothes is not only related to fabric composition, but also related to many factors, such as brand, design, pattern, workmanship, dyeing and so on. The same cotton-padded clothes may be as long as dozens of pieces and thousands of brands, and the fabric composition is not accurate.

Don't feel warm just because it's polyester. In fact, the warmth retention of hollow polyester fiber filler is not worse than cotton, but it is much better to take care of, and it can be worn after machine washing and drying.
