The filling quantity of children's down jacket is one of the important indexes to measure its warm-keeping performance. Generally speaking, the higher the filling amount, the better the thermal insulation performance. However, the filling amount of down is not the only measure, and the quality of down and the warmth of fabric need to be considered.

According to the national standard of Down Jacket (GB/T14272-2011), the cashmere content of down jackets should be no less than 50%. This means that if the cashmere content of a down jacket is 90%, then its cashmere filler is 90%. However, this standard does not apply to children's down jackets.

For children's down jackets, it is generally recommended to choose products with cashmere filling between 50% and 80%. This is because children are small and have weak tolerance to cold. Therefore, too much cashmere filling may make children feel overheated and affect their comfort. At the same time, too low cashmere filling may not meet the children's warm needs in cold weather.

In addition, it should be noted that different brands of children's down jackets may have different cashmere filling standards. Therefore, when purchasing, we should not only check the cashmere filling amount of the product, but also refer to the recommended size and warmth grade of the brand.

Generally speaking, the filling amount of children's down jackets is not as much as possible, but needs to be selected according to the age, body shape and activity intensity of children. Generally speaking, 50%-80% cashmere filler can meet the needs of most children. At the same time, we also need to pay attention to the quality of down and the warmth of fabrics to ensure that children can stay comfortable and warm in cold weather.
