Speaking of popular down jacket styles, in addition to Canada Goose 's "Parker Down Jacket" and Bosideng 's "Windbreaker Down Jacket", the most popular ones should be Uniqlo 's "Light Down Jacket".
No bragging, brand prejudice aside, is Uniqlo’s “Light Down Jacket” worth buying?
Analysis of Uniqlo's "Light Down Jacket"

As long as the clothes are filled with "down", can they be called "down jackets"? If you don’t measure a down jacket’s standards to determine its warmth-keeping effect, why buy a down jacket instead of a cotton jacket?
To judge the warmth of a down jacket, we mainly look at three factors : down content, down filling and bulkiness , all of which are directly proportional to the warmth, that is, the higher the three indicators, the better the warmth.
1. Warmth retention
(1) Down jacket with velvet content
The higher the velvet content, the better the thermal insulation effect. The standard is: cashmere content should be no less than 70%, and light and thin models must reach 90%.

The down content of Uniqlo's "Light Down Jacket" is 90%, which is just up to standard; it uses gray duck down filling, which has less warmth than goose down.
(2) Down filling amount
Down filling amount can be flexibly adjusted according to regional differences: South (about 100g); North (more than 200g).

Most of Uniqlo's "light down jackets" have a down filling capacity of around 60g, and the thermal insulation effect is not up to standard.
(3) Fill power
Generally speaking, a down jacket must have a fill power of more than 600 to keep warm enough. For down jackets without a fill power label, you can press it with your hands and see the rebound speed of the down jacket. The higher the fill power, the higher the fill power.

Uniqlo's "Light Down Jacket" does not have a clear standard for how much fill power it has, but looking at it with the naked eye or by pressing it, it is enough to show that its fill power is not up to standard.
2. Cost price

The reason why Uniqlo's "light down jacket" is so popular is that in addition to the brand effect and fashionable appearance, most people buy it for the low price.
However, 199, 299 yuan a piece of light down jacket, what is its cost price? Is the price/performance ratio really high?

One kilogram of duck down costs 350 yuan, and 60g of down only costs 20 yuan, that is, the cost of "down" is 20 yuan;
plus fabrics, accessories, and processing fees, the cost of a Uniqlo light down jacket is about 90 yuan.
If calculated based on the price of 199 or 299 yuan, Uniqlo's down jacket is not very profitable, but Uniqlo is very smart and knows that as long as there is "sales volume", the profit will be higher.
3. Fashionability

There is a saying. Uniqlo’s “light down jacket” definitely beats ordinary down jackets in terms of fashion.
's thin and light style design does not look bulky at all when worn; whether it is short or medium-length, it has excellent plasticity, is fashionable and versatile.

In the southern region, Uniqlo's light down jacket can meet the needs of warmth and dressing. It can be worn directly as an outer jacket, which is light, comfortable and stylish;

Summary:
Regarding whether Uniqlo’s “Light Down Jacket” is worth buying? I think everyone already has the answer in mind.
First of all, light down jackets are not as warm as ordinary down jackets, and people who pursue warmth are not recommended to buy them;
Secondly, those who pursue cost performance and do not consider warmth can consider Uniqlo light down jackets;
Finally, they are suitable for the southern region. It is too cold in the north to wear Uniqlo light down jackets that are not warm enough.
