The weather is getting colder and the down jacket market is also beginning to be hot. Various slogans such as "light" down jackets and windproof and breathable are dazzling. How to avoid the misunderstanding of buying down jackets and pick out down jackets that are truly warm?
According to the national standard of down jacket, the down jacket shall not be less than 50% down. The higher the down content, the better the warmth of the down jacket. However, generally choosing 70%-80% of the velvet content can meet the demand. It is not that the more down and the heavier the clothes, the more warm the down jacket. Because as the packing density increases, the heat loss through the conduction of the packing also increases. It is normal for high-quality down to contain a certain limit of fine hair stalks. If it is particularly soft to the touch and cannot touch the stalks at all, such products should be purchased with caution. This is because some manufacturers will smash leftovers, fluffy cotton, and feathers and fill them in clothes to deceive consumers as down. Understanding the above misunderstandings makes it easier to choose. Here are some tips for judging the quality of down jackets:
1. Look
Check if there is a product quality label, test report, and whether the down type, down content and down filling amount are clearly marked on the label.
2. Touch
Good quality down jackets feel soft to the touch, with intact hairs, feather stalks but not many, and at the same time, ensure that the hair stalks are soft.
3. Press
Press down on the down jacket with your hand and release it immediately. If it rebounds quickly and returns to its original shape, it indicates that the down has a good fluffy degree. Poor resilience and a heavy feeling in the hand indicate that the velvet content is low, or a certain amount of raw flakes or crushed hair are mixed.
4. Shoot
Pat the down jacket vigorously. If the down comes out, or there is dust spilling at the stitches, it means that the fabric has poor anti-fleece resistance, or the sewing needle is too large, and the down jacket will be thinner. Some down jacket fabrics are not velvet but also waterproof, but they have poor air permeability and are not easy to emit water vapor. They are not easy to dry after washing. When the down is damp, it will deteriorate in different degrees, or breed microorganisms and emit a bad smell.
5. Smell
Smell the down jacket with your nose close to it. If there is an obvious peculiar smell or odor, it may be filled with inferior down jacket. It is recommended not to buy it.
6. Carry
Pick up the weight of the down jacket, the lighter the weight and the larger the volume, the better.
Finally, pay attention to tailoring when buying. The more grids used to fix the down, the better, otherwise the down may clump and sag after washing several times.
