Why are fewer and fewer people wearing cotton-padded clothes and trousers now?

Nowadays, fewer people wear cotton-padded clothes and trousers, because people pay more attention to fashion and warmth, and they all choose down jackets. Down jacket is fashionable, warm and light, which is the first choice for many people. Although cotton-padded clothes and trousers have a good warm-keeping effect, they are cumbersome to wear. When they are active, their bodies will become heavy and inflexible, which will bring inconvenience to their actions. So few people wear cotton-padded clothes and trousers now.
