Down jackets 羽絨外套

When it comes to insulating qualities, nothing can outclass down as padding. Down offers unbeatable heat in relation to its weight and is fluffy, comfortable and easy to compress. Down is therefore the obvious choice for expeditions or treks in extremely cold temperatures and at high altitudes. It is also the best option on really cold days for activities that are more sedentary, such as ice fishing or dog sledding.

Fjällräven has been working with down insulation for more than 40 years and we exclusively use down of the highest quality. When experienced adventurers told our founder, Åke Nordin, that their warm garments did not keep them warm enough, he made a decision. No one should ever again have to freeze while out in nature. This decision resulted in the launch in 1974 of the now classic Expedition Down Jacket, and since then our down jackets have become much appreciated across the world.

Down jackets of the best quality

High down quality and smart constructions are just two of the reasons why our down jackets are so popular. One of the technical terms you may come into contact with is CUIN (sometimes also called fill power). This is a measurement that indicates how fluffy the down is. You may also hear the terms loft and insulation, which refer to the thickness of the layer of air created by the padding and, respectively, the warming properties of the insulation. The thicker the loft, the better the insulation. The loft is determined by the blend of down and feathers. For maximum insulation, you should choose a down jacket with a high CUIN and a good mix of down and feathers.

CUIN measures insulation

CUIN stands for cubic inches per ounce and indicates how much volume (cubic inches) is filled by one ounce (27.3 grams) of down. For simplicity sake, we can say that the higher the CUIN value of a jacket, the better it insulates (assuming everything else equal).

Mix of down and feathers

Down binds more air than feathers and also offers better insulation. This means that the higher the percentage of down in a jacket, the better the insulation compared to a jacket of the same weight. If you see information such as “90/10”, this means that for every 100 grams of padding in your jacket, 90 grams are down.

More details that make a difference

Our down jackets are popular and warm just because of their high-class down and high down ratio; they have large, roomy hoods with a drawstring opening that leaves only the eyes visible when pulled tight in really cold weather. Many also have detachable synthetic fur trim for protection from the snow. Protective flaps at the zipper stop drafts and push buttons add extra security (a broken zipper in the winter mountains could be a major problem). But the flaps also offer flexibility - by closing the jacket using only the buttons, moisture and heat can be released.

We often add extra hand-warming pockets behind the regular pockets and the shoulders are filled with extra padding to ensure that they maintain their warmth and shape even when carrying a backpack or heavy items in the pockets.


Fjällräven擁有超過40年製造羽絨產品的經歷,我們堅持只用頂級的羽絨。實際經歷過的探險家向我們的創始人Åke Nordin表示,當時他們所穿著的保暖衣服效果不彰,Åke Nordin因此下定決心,不再讓人於自然界受凍。這個決心造就了1974年推出的經典Expedition Down羽絨外套,自那時起,我們的羽絨外套就享譽全世界。


高品質的羽絨和精心的設計,是我們的羽絨外套如此受歡迎的兩個關鍵。你可能聽過CUIN(蓬鬆系數,又稱fill power)這個術語,這是衡量羽絨蓬鬆度的一種測量法。另外的術語還有loft(蓬鬆度)和insulation(保暖度),分別代表填充物所構成的空氣層的厚度,以及保暖效果。蓬鬆度越高,保暖效果越好。而蓬鬆度取決於羽絨和羽毛的比例,如果要獲得最高的保暖度,就要選擇高蓬鬆係數(CUIN),並且羽絨和羽毛比例完美的羽絨外套。


CUIN(蓬鬆系數)等於cubic inches per ounce,代表每盎司(27.3克)的羽絨可以填充的體積(立方英吋)。簡單來說,一件外套的CUIN值越高,保暖度就越佳(在其他條件相同的情況下)。
