How to judge whether a down jacket is warm

Whether a down jacket is warm or not includes the following factors:

1. Fabric thickness and craftsmanship
The thicker the fabric, the warmer it is. The fabric craftsmanship characteristics of windproof and rainproof are definitely more cold-proof.
The thickness of the fabric mainly depends on the "gram weight", and windproof and waterproof depend on the production process.

Whether the fabric is thick or not can be judged by ordinary consumers by touch and vision, but the fabric craftsmanship requires professionals like us to judge. Consumers who want to understand the fabric craftsmanship need to read the instructions or consult sales staff.

In fact, the thickness and rainproof level of the down jacket are not the higher the better, but a comprehensive choice should be made according to the clothing style and design application scenario.

From a design perspective, if the absolute thickness and rainproof characteristics are chosen for the warmth of the fabric, then the finished down jacket will be bulky, ugly, and not breathable. What is the difference between that and wearing a worn-out cotton coat.

Therefore, when choosing the fabric of the down jacket, the down jacket designer should not only consider warmth but also aesthetics, and also determine the application scenario and consumer positioning of the down jacket.

Since down jackets have so many detailed features, consumers must consider the application scenarios of the down jackets before buying them. If you are in an extremely cold area, such as a city like Harbin, then warmth must be the first priority, beauty is the second, and both are taken into consideration; if you are in the middle and lower reaches of the Yangtze River, then most of the down jackets on the market are basically suitable; if you are in Guangdong, then most of the down jackets on the market are definitely too thick, and you should choose the thin and light "Autumn Down" series

2. Style, structure, and windproof design

Long down jackets are definitely warmer than short ones;

The windproof design is mainly reflected in the windproof hood, collar and windproof sleeves;

The clothing hierarchy must choose a four-layer structure (face, bladder, bladder, lining), and avoid a three-layer structure;

In fact, the above design is the basic design of a cold-resistant down jacket.

3. Filling

The filling in the down jacket is the pit that consumers are most likely to encounter.

There are many counterfeit and inferior products on the market. They are branded as down jackets, but the filling is replaced by "down cotton". Down cotton is also called "vacuum cotton". It is not down, and the warmth retention performance is not the same as down. It is just a very misleading name to fool consumers, so consumers must avoid it.

So how to distinguish whether the filling is "down" or "down cotton"? In fact, we can clearly know what the filling is by just looking at the tag or washing label.

Look, the column of filling above clearly describes "polyester fiber", which means that it is not down; if the filling is down, look at the tag or washing label below, this column describes "duck down or goose down".

Some friends think that this tag can be faked. In fact, this worry is unnecessary. Unless you can't find the manufacturer of the three-no products, any slightly formal factory will not dare to fake the tag. If it is faked, it can be fined and closed immediately or even imprisoned. The information on the tag can be routine, but it is definitely not allowed to be faked. In fact, most manufacturers dare not even try routines, just like the tag above, which honestly writes "polyester fiber", but even so, there are still consumers who are fooled by illegal vendors.

There is no need to doubt the authenticity of the tag and washing label. Of course, you can't guarantee the authenticity of the three-no products you buy at a roadside stall.

In addition, even if the filling material is down, we still need to pay attention to another detail, that is, the down content. The down content is closely related to warmth. The more down content in a unit space, the more fixed air, and the warmer it will be (air is a poor conductor of heat, which is also the warmth-keeping principle of down jackets). Generally speaking, we try to choose down with a down content of 90%.

The down content of a piece of clothing is generally described on the tag and washing label.

4. Filling amount

Generally speaking, the more filling, the better, but there is still a problem of degree. If a down jacket is filled with too little down, it will not keep warm even if the down is good, but if the filling is too much, it may increase the cost and may also produce marginal effects. What is the marginal effect of the filling amount of a down jacket?

It can be said that the filling interlayer space of a down jacket is limited. The principle of warmth preservation of our down jacket is to use the high fluffiness of down to lock the air. If we fill enough down in this limited space, it will only lead to a decrease in the locked air, and the down itself does not generate heat, which may even have the opposite effect.

This is also the reason why most of the filling volume of my country's big-name down jackets is 100-200g. One is to adapt to the temperature in most parts of my country, and the other is to prevent excessive waste of costs without achieving the purpose of improving warmth.

This is why I say in many places that those who only emphasize the fluffiness are laymen. First, the national standard has already stipulated the fluffiness corresponding to our down content standard. 90% down basically meets the better fluffiness. Second, 800+ fluffiness down and 700+ fluffiness down are filled into the same space in unit quantity. Due to the reverse pressure of the down jacket lining interlayer, this fluffiness difference will not lock more air in the interlayer. Therefore, the fluffiness corresponding to the down with a down content of 90% is enough to ensure a corresponding warmth. There is no need to pay too much attention to the fluffiness.
