Down fabric is not the most ideal choice for moisture wicking effect. Down jackets usually use down padding with polyester or nylon fabrics, which do not have a good moisture wicking function. In contrast, fabrics such as sportswear that are specifically designed to absorb moisture and wrest sweat are more suitable.

The outer fabric of the down jacket is usually made of synthetic fiber materials such as polyester or nylon, which do not have good air permeability and moisture absorption and sweating function. And because of the characteristics of the down filler, the overall breathability is not as good as other fabrics. Therefore, in intense exercise or high-intensity activities, wearing a down jacket is easy to cause sweat to be unable to discharge in time, making the body unable to keep dry and comfortable.

In addition, the thermal insulation effect of the down jacket mainly depends on the thermal insulation performance of the filler, rather than the moisture absorption and sweating function of the fabric itself. Therefore, although down jackets perform well in terms of warmth, they still need to be improved in terms of ventilation and perspiration.

In view of the shortcomings of the poor moisture absorption and sweating effect of down jacket fabrics, some brands are also constantly innovating and improving. In recent years, some brands have launched down jacket fabrics with breathable and perspirant function, through technical treatment or special design, to enhance the fabric's breathability and moisture absorption and perspirant effect, making it more comfortable and dry when wearing down jackets.

In general, the moisture absorption and perspiration effect of down jacket fabric is not the most ideal choice, compared with fabrics designed for sports and outdoor activities, its air permeability and moisture absorption and perspiration function need to be improved. If you need to wear a down jacket in a humid or high-intensity exercise environment, it is recommended to choose fabrics with breathable and perspirant functions, and choose appropriate clothing matching according to the actual situation to ensure that the body is comfortable and dry.
