ABOUT THE DOWN 01
A concern for quality
NANGA down is carefully selected at sites where it is produced, and aims at the highest quality. Washed and refined domestically, NANGA guarantees the utmost in quality.
NANGA uses the down from mature waterfowl. Because it is washed and refined domestically, it has the high functionality for temperature and humidity control that belongs essentially to down, and is sturdy without the smell that is peculiar to down.
ABOUT THE DOWN 02
Hungarian Silver Goose
Only Hungarian Silver Goose down is used, which is washed domestically. 90-7% down with a fill power of 930 FP, a very high degree of thermal insulation.
Only Polish White Goose down of the highest quality is used, which is washed domestically. 93-7% down with a fill power of 860 FP, a very high degree of thermal insulation.
Ultrahydrophobic (super water-resistant) processing is added to DX down, yielding a high quality, high performance down with a fill power of 770 FP. Down and a water-repellant resin are joined at the molecular level, blocking the permeation of water by making a wall of fine particles. It is the highest grade of down, which "lets moisture pass through, but does not absorb water."
Only European White Duck down is used, which is washed domestically. 90-10% down with a fill power of 760 FP. It is a high-quality down, excelling in cost and performance.
Fill power index (FP)
expresses the "down strength" and "resistance to pressure" according to standards for measuring down. A fill power of 760 means that if 30g of down is pressed down on with normal pressure in an experiment, it shows a resistance of 760 cubic inches. The higher the FP rating, the better the down is.
Bulkiness (Fill Power)
The quality of down is examined by the IDFL (International Down and Feather Testing Laboratory) of the United States, and only down that has met each fill power is used.
