In the face of all kinds of down jackets at all prices, do you make many people look dazzled? A practical down jacket in winter can make you warm a lot, so do you know how to choose the most suitable down jacket?
Four key words for choosing down jacket
Key words 1: cashmere content
Down content refers to the percentage of down and down silk in down.
According to the standard of down clothing, down clothing with down content less than 50% cannot be made. The down content of down clothing is generally 70% or above, and generally 70% - 80% down content can meet the demand. In order to pursue 'light' and 'thin' down clothing, the requirement of down content is higher, generally more than 90%. The higher the down content, the lighter the weight and the better the warmth retention of the same volume down jacket.
Key words 2: filling quantity
Down filling is the weight of all down filled by a down jacket.
Take the down clothing with about 90% down content as an example. Generally, if the temperature is between 0C and 10C, the autumn thin clothing with 76g / m down content can be selected. If the temperature is between - 10C ~ 0C, the winter thin fabric with 92g / M filling capacity can be selected. When the temperature is lower, the filling quantity needs to be higher.
[reminder] it's not that the more down filling and the heavier the clothes are, the warmer the down jacket will be. Because with the increase of the filling density, the heat loss through the conduction of the filling material also increases.
Key words 3: fluffy degree
Fluffy refers to the volume per ounce (30g) of down in cubic inches under specified external conditions.
An ounce of down takes up 600 cubic inches of space, which is called 600 fluffy. The standard of fluffy degree in China is 450. The more fluffy the down is, it means that the down with the same amount of filling can fix a larger volume of air layer to heat and insulation, so the better the warmth retention of down.
Key words 4: Fillers
The most common filling materials in down jacket are goose down and duck down, including white goose down, grey goose down, white duck down and grey duck down.
Generally speaking, the bigger and more mature birds have better quality of fluff, which means they are more warm. The warmth retention of goose down is slightly higher than that of duck down, but the difference is very small, which can hardly be felt by human body. Because the production of goose down is small, the price is high. There is a saying in the market that white duck down is better than grey duck down
It's not accurate. White duck down can be used more widely in down clothing with light color, but there is no difference in warmth retention between the two except for color difference.
8 steps to choose a down jacket
At first glance
T look at the label. Check whether there are product quality labels, test reports, etc., and whether the down type, down content and down filling quantity are clearly marked on the labels.
2. Look at the fabric. The fabric of the light and thin down jacket is soft. If the fabric looks rough, the quality of the down jacket is not good.
Two press
Press the down jacket with your hand and release it. If it rebounds back to its original state quickly, it means that the fluffy degree of down is good. If it has poor resilience and a heavy feeling in the hand, it means that the content of cashmere is low, or it may be mixed with a certain amount of wool flakes or crushed wool.
Three kneading
Pinch the down jacket by hand. If the hair stem is not obvious, the content of cashmere is higher, otherwise it is lower. But if it's very soft to knead, and the stem can't be kneaded at all, you should purchase it carefully. Because some manufacturers will break the scraps, fluffy cotton and feathers, and then fill them into clothes, as down to cheat consumers.
Four smell
Nose close to down jacket, smell carefully. If there is obvious odor or odor, it may be filled with inferior down. It is recommended not to buy.
Five beat
Take a hard pat on the down jacket. If there is down running out or dust overflowing at the stitches, it means that the fabric has poor anti drilling property, or the sewing needle hole is too large, and the down jacket will pass through more, but the air permeability is thin. Some down clothing fabrics are waterproof without drilling down. Down is not easy to emit water vapor due to the tidal range. It is not easy to dry after washing, which will produce different degrees of deterioration, or breed microorganisms and give off a bad smell.
Six points
To weigh down a down jacket, the lighter the weight and the larger the size, the better. For the same weight, if the cashmere content is 30%, the volume is more than twice that of cotton; if the cashmere content is more than 70%, the volume is more than twice that of cotton.
Seven squeeze
According to the standard, down jacket should have certain air permeability. Consumers can squeeze the back of the down jacket with their hands to extrude the air out of the down jacket. If it is not easy to extrude, it means that the air permeability is poor. If it can extrude slowly, it means that it has certain air permeability. For example, the air permeability of down is poor. First, the water vapor in the process of wearing is not easy to emit, and it is easy to get wet and feel uncomfortable and not warm. Second, it is not easy to dry after washing. The above two factors will make down damp and deteriorate in different degrees.
Eight election
When purchasing, pay special attention to whether there is plastic film and fake airtight lining in the lining of down jacket. Pay attention to the cutting. The more checks you use to fix down, the more
Well, otherwise, after several times of washing, the down may agglomerate and droop like a gourd. People who plan to travel long distance should choose the down jacket which is small in size, light in weight and can be compressed and put in the backpack. For those who need to stay in cold environment for a long time, it's better to choose a long-term down jacket with wear-resistant fabric and more pockets for personal belongings. It's better to have a cap with a burr to protect against wind. For the down jacket and vest that you wear inside, you should choose the one that is relatively close to you.
