How to choose down jacket?

1. Learn about down jackets

Down jackets all look similar on the outside, but the padding inside is quite different. Down jacket is warm, the main reason is that it is filled with down, can prevent the loss of body temperature; Moreover, the shagginess of down is also an important reason for the warmth of the down jacket, and the thick and airtight outer fabric of the down jacket can increase the warmth of the down jacket. So whether a down jacket is warm, mainly depends on the material of down, how much down, how much thickness of air layer can be provided after fluffy down.

2. How to choose a down jacket

01. Down content

The thermal insulation material inside the down jacket is composed of down and feathers, and the down content is the proportion of down in the down jacket. The down jacket on the market rarely uses 100% pure down. Because the padding in the down jacket needs a certain amount of support, there will be a certain proportion of feathers, which is what we call the down content.

But feathers have two disadvantages over down:

① Feathers are not fluffy and do not contain air like down, so they do not keep you warm.

② Feathers are easy to drill down and will run out of the cracks in the fabric.

Therefore, when choosing, it is recommended to choose down jackets with fewer feathers to prevent a large number of drill down.

There is also a standard for down jacket: its down content shall not be less than 50%, that is, only those with more than 50% down content can be called “down jacket”. At present, the down content of slightly better quality down jackets is more than 70%, while that of high-quality down jackets is at least 90%.

Therefore, the key indicator of the quality of down jacket is the down content. The higher the down content, the better the thermal insulation effect.

Down filling amount:Even if the content of a down jacket is very high, but its filling amount is small, it will affect the thermal performance of the down. However, it is not an absolute value, and you can adjust it depending on the area or scope of use. For example, if you want to climb the snow mountain in the South and the North Pole, the down jacket is usually more than 300g

If the down content and filling amount are equivalent to the “amount” of down, the fluffy degree basically represents the “quality” of down jacket, which is based on the cubic inch volume of down per ounce.

Down jacket relies on down to prevent heat dissipation to achieve super warmth retention. The fluffy fluff can store a lot of static air and lock the temperature in the body.

Therefore, the thermal insulation performance of down jacket requires a certain degree of fluffy to form a certain thickness of air layer inside the clothes to prevent the loss of hot air.

The higher the fluffy degree, the better the warm keeping function when the filling amount is equal. The higher the puffiness, the more heat insulation air the down contains, and the better the heat insulation performance.

In addition, it is very important to keep the down jacket dry and cool to keep it fluffy. Once wet, the down jacket with good fluffy degree will be greatly discounted.

When buying down jackets with high fluffy degree, pay attention to whether they contain waterproof fabrics. For example, it is recommended to choose waterproof and moisture-proof fabrics in extremely cold regions.

1. Classification of down jacket

Down is long in the belly of the goose, duck fluff, and into a flake called feathers, it is the main padding down jacket, is the closest to the surface of the bird body, the best warmth.

At present, the widely used down on the market are: goose down and duck down.

But it’s also called a down jacket. Why is goose down more expensive than duck down?

01. Different fiber structures (different bulkiness)

The goose down rhombohedral knot is smaller, and the pitch is larger, while the duck down rhombohedral knot is larger, and the pitch is shorter and concentrated at the end, so the goose down can produce larger distance space, higher fluffy degree, and stronger warmth retention.

02. Different growth environment (different tufts)

The goose down flower is relatively large. Generally, the goose grows to maturity for at least 100 days, but the duck only has 40 days, so the goose down flower is more plump than the duck down flower.

Geese eat grass, ducks eat omnivore, so eiderdown has a certain smell, and goose down has no smell

03. Different feeding methods (odor generation)

Geese eat grass, ducks eat omnivore, so eiderdown has a certain smell, and goose down has no smell.

04. Different bending properties

Goose feather has a better bend, thinner and softer than duck feather, better elasticity, more resilient

05. Different time of use

The use time of goose down is longer than that of duck down. The use time of goose down can reach more than 15 years, while that of duck down is only about 10 years.

There are also many careful businesses that will mark white duck down, gray duck down, white goose down and gray goose down. But they are different in color, and their warmth retention is just the difference between goose down and duck down.

Therefore, the down jacket made of goose down is better in quality than that made of duck down, with larger down flowers, good fluffy degree, better resilience, lighter weight and warmth, so the price is more expensive.
