In cold winters, people usually wear down jackets to protect against the cold. Down jackets are not only lightweight but also relatively warm compared to cotton and other materials. So, why can down jackets play such a role?

The down jacket has excellent thermal performance is determined by its structure. The down of the down has a flower-like structure, which is composed of a down core and a lot of filaments emitted from the down. Wool is composed of many tiny hollow structure scales, which contain a large amount of still air. The low thermal conductivity of air creates a natural barrier to the flow of hot and cold air. In addition, the unique three-dimensional branch-like structure of the down makes the down bulkier and warmer than other insulation materials of the same weight (such as camel, cashmere, silk, cotton, chemical fiber, etc.).

In order to be able to spend a warm winter, how do we judge the quality of down jackets?

We can identify down jackets in five steps.

First, look. Is there a product quality label, test report, etc., and whether the type of down, content, and filling amount on the label is clearly marked?

Second, touch. A good quality down jacket feels soft to the touch, has a complete pile of hair, and has feather stalks but not many. At the same time, it must ensure that the stalks are soft. Then weigh the weight of the down jacket. Generally speaking, the lighter the weight and the larger the volume, the better.

Third, press. Press the down jacket with your hand and release it. If it rebounds quickly and returns to its original state, the fluffiness of the down is good. Otherwise, the rebound resilience is poor, and a heavy feeling in the hand indicates that the pile content is low, or a certain amount of flakes or crushed hair may be mixed.

Fourth, shoot. Take a hard shot of the down jacket. If there are down drills or dust overflowing at the pins, it means that the fabric is poorly drilled or the stitches are too large. The down jacket will be thinner.

Fifth, smell. Keep your nose close to the down jacket and smell it carefully. If there is obvious odor or odor, it may be filled with inferior down. It is recommended not to buy. More click here: down jacket manufacturer and supplier
