china columbia down jacket FACTORY - If you need to wear it as the outermost layer for a long time, and you may be engaged in outdoor, industry and other work activities while wearing, the down jackets for these purposes need to have strong protective fabrics to ensure performance and strength, so there will be high-strength multilayers. Gore-tex, windstopper, or major brands' own waterproof and windproof fabrics are protective thermal down jackets.
china columbia down jacket FACTORY - Four indicators of down jackets:
1. Down content: (down/feather ratio, Down/Feather)
A bird's down output is relatively limited, mainly concentrated in the neck to the chest and abdomen area. The feathers in this part are in the shape of down, with fine fibers, more branches, and more fluffy. It has excellent thermal performance and is the main component of down materials. section. Other areas of the body are dominated by flaky feathers, with feathers of varying thickness in the middle, which have a great difference in warmth compared with down.china columbia down jacket FACTORY
Therefore, the down content, or down/feather ratio, is a key factor in determining the quality and warmth performance of a down jacket under the same conditions (type, bulkiness, down filling, etc.). The higher the ratio, the higher the warmth performance of the down jacket. More excellent.china columbia down jacket FACTORY
The bulkiness is an important indicator of the warmth of down and down in the world. It refers to the volume of cubic inches per ounce (30 grams) of down under certain conditions. For example, one ounce of down occupies 600 cubic meters of space. Inches, the bulkiness of the down is called 600.
For example: the same 600 fluffy European standard down will be larger than the American standard, so most international outdoor brands and shopping malls will specially mark down products, such as "850-fill European goose down", indicating that it is European standard 850 goose down; 850-fill goose down", indicating that it is American Standard 850 goose down.china columbia down jacket FACTORY
The bulkiness represents the volume of the down in its natural form. Under the same weight, the high-top down has a larger volume and voids, which can retain more air and have a better thermal insulation effect. Take an outdoor sleeping bag as an example: Under the same filling gram, high-top down has a lower comfort temperature scale than low-top down.
3. Filling amount
This indicator is easy to understand. The amount of down filling indicates the quality of down filled clothing. Under the same conditions, a down jacket with a higher filling capacity will definitely have better thermal performance, but it will also increase volume and weight. For outdoor brands and manufacturers, the main reason for designing and deciding a down jacket with the largest amount of down is the purpose.china columbia down jacket FACTORY
