Commitment to Quality

NANGAの機能
NANGA's down is guaranteed of its excellence, achieved through the careful selection of its origins, pursuit of quality, and the domestic processes of washing and refinery.

NANGA utilizes down from mature waterfowl. Washed and refined in Japan, the material boasts excellent temperature and moisture control properties inherent in down. Moreover, the processing technology removes much of the odor unique to down.

FILLING MATERIALS

Hungarian Silver Goose

This down is made from only Hungarian silver goose down that has been washed in Japan. It is 95/5 down with a fill power of 930 FP, which possesses excellent thermal insulation capabilities.

930FP Down
SPDX

This finest quality down is made from only Polish White Geese that has been washed in Japan. It is 93/7 down with a fill power of 860, which possesses great thermal insulation capabilities.

860FP Down
UDD

The down from European White Ducks (DX) has been processed with ultra water-repellent treatment, resulting in a high-quality, high-performance material with a fill power of 770. The resin of the water repelling agent binds with the down feathers at the molecular level, and the fine particles create a barrier to prevent the intrusion of water. It is the perfect down that allows the transmission of moisture vapor but does not absorb water.

770FP Down
DX

This down is made from only European white duck down that has been washed in Japan. It is 90/10 down with a fill power of 760, which is highly cost-effective and of excellent quality.

760FP Down
Fill Power Rating Value (FP)

The value is a standard of measurement to determine the loft of the down or the resilience to compression. For example, a fill power of 760 means that when 30 grams of the down is tested by compressing the down cluster under normal pressure, its loft will measure 760 square inches. The higher the FP value, the better quality of down.

Loftiness (Fill Power)

Our down is tested for quality by the US-based IDFL (International Down & Feather Testing Laboratory), and we only use materials that meet the fill power standards.
