What is 800 fill down?
What is 800 fill down?
As fill power increases, the down can trap more air which, in turn, allows more insulation from the down. For example, one (1) ounce of 800 fill power goose down will loft to 800 cubic inches.
What is the highest down fill power?
- Goose Down Fill 900. 900 fill down is the highest quality down commercially available and considered the absolute gold standard of insulation—with an unmatched warmth-to-weight ratio, it is highly compressible, ultralight and amazingly warm.
- Goose Down Fill 800.
- Goose Down Fill 700.
- Goose Down Fill 600.
What does 550 down fill mean?
Understanding fill power numbers A higher number means the down takes up more space and is capable of trapping more air. As an example, Epiq Down Jackets are filled with 550 fill power down – so in the above test, one ounce of this down takes up 550 cubic inches of space.
What is the difference between 600 fill and 800 fill down?
The more insulating air pockets down traps, the warmer it will keep you! So in simple terms, the higher the fill power of a down jacket or sleeping bag, the warmer it will be for its weight. The image below illustrates the difference in volume between a gram of 600, a gram of 700, and a gram of 800 fill power down.
What does 750 fill power mean?
Fill power can be expressed as cubic inches per 30 grams (in³/30 grams). Poor quality down might be between 300 and 500 fill power. For down sleeping bags a lofting power of 600-650 is considered good quality, 700 – 750 is considered very good, and 800 – 950+ is considered excellent.
What is the difference between 650 and 800 fill down?
A higher rating means less down fill is required to capture the same amount of heat. A 650 down fill jacket with 330g of down may be as warm as an 800 down fill jacket with only 120g, but the 650 fill jacket will be bigger, heavier and take up more room when stuffed in your pack.
Why is down so 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.
