What Is Down Fill Power (2025): Fill Weight, Synthetics

Have you ran through the term “filling energy down” while shopping Sleep bagsSwollen jackets, or Quarrel? These numbers range from 450 to 900, and sometimes above. In general-but not always-all this number, the better the warmth to weight. But what is the mobilization force in reality?

To measure the packing power, companies are doing a laboratory test to measure fluff. The technical test is the number of cubic inch of the upper floor from one ounce from the bottom. The container is filled with one ounce of insulation down, then the weight is placed on top. After one minute of weight pressure, the size is measured below under the weight. The important thing that must be taken into consideration is that the packing force is a measure of the quality of the bottom, not the quantity. The upper packing power means larger groups down, and larger groups of smaller groups flourish. The drawing below shows the difference in the upper floor between the various packing forces.

External equipment generally ranges from 500 filling forces on the low end to more than 900 filling energy for very advanced jackets and sleeping bags for the country’s cold adventures. The era (i.e. the upper packing power) also means that a blessing or sleep bag will press much smaller, making it more powerful to travel or back.

What tells you a filling force below?

The higher the packing power, the higher the upper floor. The puffy jackets and sleep bags are warm by besieging the warmth that stems from your body, keeping them in the air pockets between the bottom. The upper packing power means that download has more upper floor, which means that there is more air pockets, which means that more heat is kept. If everything else is equal, this means that a high packing power garment will be warmer than one with a lower filling energy.

Unfortunately, everything else is never equal. Power filling alone is not enough information to see the warm thing. There is no direct correspondence between the packing energy and the warm product that you will keep you, because there are many other factors that must be taken into account, such as the amount of this packing in the product and the quality of the expansion inside the pieces or design of the jacket or the sleep bag.

To find out how warm a jacket, a sleeping bag, or a comforter, you need to know at least one number: the weight of the filling.

The weight of the filling down is a simple number. It is the amount of the bottom in the product, usually measured with an ounce or fines. It can give you the use of full weight and packing strength together to compare two elements. For example, the relative warmth of a swollen jacket can be estimated by hitting the packing force with the filling weight. This means that a 900 power jacket with 2 ounces of packing weight will be the same as the warmth as a 600 -filling power jacket with 3 ounces of filling weight. The big difference between them, and the reason for its price differently, is the weight of each and the bottom size.
