Why are light down jackets warmer?

Because the down content of light down is relatively high, it is warmer. Then the composition of down is also different, some are duck down, some are goose down, so it is lighter.

It has to be admitted that cotton has some ability to keep warm, but it is still inferior to down jackets. The thicker the clothes, the warmer they are. Cotton clothes are usually thicker, which greatly hinders people's flexibility. Down jackets solve this problem. They are thin and light, not only allowing freedom of movement, but also keeping warmer than cotton clothes.

Why is the down jacket too fishy?

The smell of fishy down jackets does not mean that the quality is bad, because after being processed in the factory, the clothes will have some chemical ingredients or machine smells, so newly bought clothes must be washed before wearing. Washing and drying them frequently can effectively remove the odor of clothes.

Can down jackets made of triple-proof fabrics be washed?

Down jackets made of triple-proof fabrics can be washed, but since stains on the surface can be easily wiped off, it is not recommended to wash them frequently.

I understand that the reason why the three-proof down jackets on the market are waterproof and anti-fouling is mainly because a layer of plastic film is "plated" on the surface of the treated fabric to prevent water and oil from penetrating. This is the same as the waterproof layer we make on the bathroom during renovation, and it is the same material as the Teflon coating on non-stick pans. However, this film is very thin because it is "plated" on, so thin that it is invisible to the naked eye. The clothes that have just been bought and have been treated with waterproofing are indeed water-resistant, but no matter what three-proof fabric is, it will eventually get dirty.
