The key to judging the down jacket good or bad look at those

If you want to buy a down jacket, regardless of whether it is a casual type or outdoor super professional to speak of the type of the most basic concepts - filler, down, down, down content, down filling, fluffiness, you are sure to You've got to have an understanding of that.

1, filler

Down jacket in the filler, the most common is the goose down and duck down, these two according to the color points, can be divided into white down and gray down. In the market down jacket according to the price, sorted: white goose down & gt; gray goose down & gt; white duck down & gt; gray duck down. May be affected by the selling price of sorting, many people therefore think that these velvet in the quality of the same order, in fact, not.

Through the theoretical study of down and practical experience, color and down jacket quality is not very good or bad relationship, goose down and duck down warmth, fluffiness and so on is not much difference. As for why goose down will be more expensive, one is less production of goose down, and the second is that goose down is finer and softer. The longer fibers make it fluffier and easier to keep warm.

PS: Smell the down jacket, if you find it pungent or smelly just ignore it. Once someone explained that goose down is more expensive than duck down because goose down is odorless, while duck down has a flavor. Duck down and goose down processing is the same way, there is a flavor of the velvet (whether it is goose down or duck down) are substandard products, never buy.

2, what is the composition of down

Down jacket contains down and feathers. Down is long in geese and ducks and other waterfowl between the neck to the chest and abdomen does not contain feathers between the hair, because this part of the hair is often immersed in the water, so not only has a certain degree of waterproof, and its warmth and cold resistance is also the best hair in the whole body. In addition, because this part of the down without feather stalks, very soft, long and fluffy fibers, folding volume is small, is the production of down clothing is the most superior material. The warmth of feathers is more limited and not as good as down.

PS: Touch the inner layer of the down jacket, if you feel prickly, is that the clothes in the feather content is higher, the quality should not be very good. If you do not touch the hand is not prickly, it shows that the down content of the clothes is relatively high, the warmth is good.

3, how much down is appropriate

The down content refers to the proportion of all the filler in the clothes filled with down. For example, if you buy a down jacket that is filled with 90% white duck down and 10% white feathers, this indicates that the jacket has 90% down content and is a higher specification down jacket.

And when you decide to buy a down jacket, be sure to look at the product label tied to the collar first, down content of less than 50% you have to pay attention to, it is already not in line with the national minimum standards.

The real high-quality down jacket is usually priced at more than 300 yuan, although less than 300 is not necessarily not true, but at least the down content will not be very high, or brand out of season clearance.

4, the amount of down

Everyone must pay attention to the amount of down this thing and the amount of down is not the same as the amount of down is calculated as a percentage of the amount of down is filled with the actual feather + down content grams, and it is the size of the clothes, the length of the clothes, the style and other factors related.

Some friends like to buy a large amount of down when they are shopping for a down jacket, thinking that it will be warmer and thicker. But you must not underestimate the down content, because the down itself is very warm, 80% of the down content than 75% of the warm some.

PS: Hard to shoot a down jacket, if there is fluff or dust appears, it means that the down jacket fabric it is very poor downproof or sewing needle eye is too large, so the down jacket will be more and more through the thin, waterproof and breathable will not be too good, for this kind of it is not recommended to buy.

5, fluffiness is very important

The fluffiness is an important indicator of the degree of warmth of the international measurement of down. The fluffiness determines the "quality" of the down. In the case of the same amount of down, the higher the number of fluff, the better the function of warmth. The higher the fluffiness, the more insulating air the down contains, and therefore the better the insulation.

An average-priced down jacket has a fluffiness of about 450-500, while a slightly higher-priced down jacket can have a fluffiness of 600-900.

From the point of view of the better international models of down jackets, down jackets with a high number of tents do not have a high filling capacity. For outdoor sports as outer warmth, they usually have a high down filling and a low canopy, between 650-750. For everyday wear, a canopy of 450-500 is enough.

6, whether the down jacket is warm or not, depends on the amount of down and fluffiness! You can't just look at the amount of down~

"My family sells this down jacket with 600 grams of down, and it's super warm!" The higher the down filling, the warmer the jacket? No! The thermal insulation of a down jacket is positively related to the amount of air it can hold, and there are two factors that affect the amount of air held in a down jacket: the amount of down and the degree of fluffiness. The product of these two factors determines the thermal insulation of a down jacket of the same size. In other words, a down jacket with 200g of down and 500 puffs is likely to be less warm than one with only 150g of down but 700 puffs.

Many sellers, when describing down jackets, only know how to trumpet the amount of down and whether it's white or gray duck down. But fluffiness, a key indicator of down quality and filling process, is rarely mentioned. You may want to ask the seller more about the fluffiness of the down jacket before you buy it.
