DownTek™ is currently available in either it’s original C6 formula, or the PFC-Free™ formula..
Do Down Jackets get less warm over time?
Wet down loses its loft and all of its ability to keep you warm – and it takes a long, long time to dry. Enter synthetics. … A soaking wet jacket or sleeping bag will never be comfortable or nearly as warm as a dry one, but at least a synthetic insulated bag will retain some insulating ability.
Is down warmer than synthetic?
Contrary to popular belief, down insulation is not made of feathers. Down is actually the fluffy undercoating that provides warmth for geese, ducks and other waterfowl. … Ounce for ounce, down is warmer than nearly all synthetic insulations. Very few manmade fibers can match down’s warmth-to-weight ratio.
Why do down feathers keep you warm?
A down jacket is a jacket which has been insulated with the soft and warm under feathers from duck or geese. Down is a fantastic insulator as the loft (or fluffiness) of down creates thousands of tiny air pockets which trap warm air and retain heat, thus helping to keep the wearer very warm in cold winter weather.
What is the warmest synthetic insulation?
Patagonia has developed a proprietary insulation known as PlumaFill, which features a fuzz of microfilaments that twist out from a central continuous fiber; the company claims PlumaFill is 40 percent warmer for its weight than other popular synthetic insulations.

Is 550 down warm?
The more insulating air pockets down traps, the warmer it will keep you! … A jacket with 300g of 550 fill down, for example, will provide more warmth than one with 120g of 800 fill down. However, it will obviously weigh a lot more! It will also be far less compressible due to it having far less air to be squeezed out.

Compared to artificial fibers, down is one of the best insulators of clothing, being lighter and trapping more heat than other materials. Sportswear makers use down in their best jackets because down keeps wearers warm and dry and allows for enough airflow to prevent overheating.
Why is goose down so warm?
Down is nature’s way of keeping ducks and geese warm. Between the bird’s body and thick outer feathers is a layer of fluffy down that traps air molecules in small pockets, creating an effective thermal barrier. … Ounce for ounce, goose down is warmer than synthetic insulations.
Which insulator is the best?
A: The best insulator in the world right now is most probably aerogel, with silica aerogels having thermal conductivities of less than 0.03 W/m*K in atmosphere. of aerogel preventing ice from melting on a hot plate at 80 degrees Celsius! Aerogel has its amazing properties because it’s mostly made out of air.
Why is down a good insulator?
Down feathers are great thermal insulators. The loose structure of down feathers traps air. As a result, energy cannot be transmitted easily through down feathers. This means birds are insulated from cold air outside, plus their body heat doesn’t escape easily either.
Is 600 fill down warm enough?
A down fill rating of 600, for example, means that one ounce of down can cover 600 cubic inches. … When purchasing a high quality down fill jacket, you should look for a fill power rating of at least 550. A jacket of this caliber will be both warmer and more comfortable.
Is Thinsulate warmer than down?
