You have run through the term “down while shopping for Sleeping bagpuffed jacket, or blanket? These figures range from 450 to 900, and sometimes above. In general, but it is not always the higher the number, the warming rate on the weight better. But what is the real power filling?
To measure strength, companies perform a laboratory test to measure the hair level. The technical test is how many inches of the attic come from an ounce or less. A container is filled with an insulation ounce, then a weight is placed on the head. After a minute of compressed by weight, the weight drops below the weight measured. It is important to remember that the strength of filling is the quality measure of down, not quantity. Higher filling capacity means larger clusters, and larger clusters to fade more than smaller clusters. The graphics below illustrate the difference in the loft between different fill power.

Outdoor equipment usually ranges from 500 low -leveled capacity to more than 900 fillings for super light jackets and sleeping bags for cold weather adventures. The height (meaning higher filling capacity) also means Parka or sleeping bags will be much smaller, making them more packaged to travel or wear a backpack.
Down Fill Power tells you what?
The higher the capacity to fill, the larger the loft. Go down to the bulging jacket and sleeping bag to keep you warm by trapping warmth out of your body, keeping it in the middle airbag. A higher filling capacity means a decrease in a loft, which means there is more airbags, which means retaining more heat. If everything is different, that means a higher fills of energy clothes will be warmer than one with lower filling capacity.
Unfortunately, everything else is never equal. Pouring power is not enough information to know how warm it will be. There is no direct correspondence between the energy filled and the product will keep warm, because there are many other factors to consider, as many of them are in the product and it can be well expanded. How in the cut or design of a jacket or sleeping bag.
To know how warm a jacket, sleeping bag, or comforting bag, you need to know at least others: the weight filled.

The weight down is a simple number. It is a decrease in the product, usually measured by ounce or grams. Using to reduce the weight and reduce strength with each other can give you a comparison of two items. For example, the relative warmth of the bulging coat may be estimated by the efficiency of the filling capacity. This means that a 900 electric jacket with a weight of 2 ounce will have the same warmth with 600 times electric jacket with 3 ounce weights. The big difference between them, and the reason they have different prices, is the weight of each and the packaging size.
