Never again freeze! Down jackets are outstanding heat in winter and glacial temperatures. Maximum heat output at minimum weight – sometimes just simply the best work nature. Whether women or men, whether who would not freeze expedition, snow-shoe hiking, trekking tour or leisure – should be reviewing down jackets or down jackets!
Down: the beastly good insulation
The fine dress down to ensure birds sure that they can keep their body heat despite water and cold ambient temperatures. A kilogram down consists of up to 500,000 individual feathers that have a unique insulating effect thanks to their special structure of soft, long, radially arranged spring branches. < Br > < br > down jackets are an ideal companion for many situations therefore in winter: more easily filled and fashionable variants provide warm and dashing look in the city, with fat-filled models man survives even the hardest climb in icy temperatures.
For what applications?
From the climb under extreme conditions until the visit of the Christmas market in the city – down jackets there for all situations in which cold plays a role and in which one not quickly and diaphoretic moves. However, there is a limit: down jackets of less suitable for rain. For one, because no dampness stomach down and on the other hand, because it’s usually too warm for the fine spring in rainy weather. < Br > < br > ever after main usage orientation special attention is paid to individual aspects in the various models. Everyday models are equipped with fashionable cuts and small-to medium-sized amount of down. For full speed with extreme temperatures emphasis firstly on a weight and pack size optimization, on the other hand of course on the maximum heat output. < Br > < br > in hybrid jackets combines the advantages of the down with the advantages of synthetic fibres: for body zones, where more moisture due to welding, synthetic fibre is used, for the fuselage, which must be kept warm, down used. < br > < Br > you can sum up: down jackets are so whenever it is cold, but not wet.
What mean bulking power, cuin and details such as 90/10?
Bulking power (power): The higher the value, which is specified when the bulking power, better insulated and warm jacket in proportion to their capacity. This value in cuin (cubic inches) is measured. He indicates on which volume an amount of down again expands, after it has compressed them into a measuring container for 24 hours. 700-800 cuin are top values, 600-700 very fine and values under 500 indicate a significantly lower insulation. ratio of down and feathers: down (90/10), for example, that is the down jacket with a mixture of 90% down and 10% Feather filled. This is a very good relationship, because a small amount of feathers must be mixed to down, to stabilize and to avoid a caking. As a rule of thumb: for clothing for extreme conditions, the mixing ratio should be at least 90/10, for other applications, 80/20 is already a very good mix. fill quantity: the amount of down filled jacket with the is, expressed in grams. The more in it, the jacket is the thicker and warmer.
Buying advice: pay attention to details in down jackets!
Cut of the jacket: a Lightweight fleece under it fits? Zippers: Are they smooth? There a protection hook? At the most down jackets the outer layer is made of very light and sensitive fabric – zippers could be jamming and wreak such havoc. Weather protection: down jackets are usually not windproof and water-repellent only. So, an important question is whether the jacket under the Hardshell fits. Insulation: For use at low temperatures should be avoided on quilted seams. Such seams work as bridges and significantly reduce the insulating effect of the jacket. Handling: Zippers and drawstrings (E.g. on the hood) should be adjustable even when wearing gloves.
The principle decision: Dear a down or synthetic jacket?
Down has better thermal performance compared to synthetic fibres, it puts less weight on the scale and can compress better. She can play as their trump cards, where it is really cold. < Br > < br > the downside: down jackets are sensitive to water as opposed to synthetic jackets. The springs can be wet, they clump together and lose their insulation properties. For permanently sweaty activities and rainy weather, synthetic fiber will be more choice.
