Specification before color
Grey down can be considered where shell opacity makes color less critical. Color does not establish fill power, cleanliness or warmth. Compare tested lots under the same method and review appearance in the finished construction.
Application fit
Dark-shell jackets, sleeping bags and opaque-shell bedding.
Agree the specification before ordering
Confirm composition definitions and tolerances, species, permitted color variation, and loft with its units, method and conditioning. A product name or blend ratio is not a fixed stock specification.
Select the relevant standard and edition for the destination market: EN · JIS · USA-2000 · KS · GB/T · QB/T · CNS. Ask for lot-linked composition, loft and cleanliness results against your acceptance criteria; approve the sample in your actual construction.

Questions, answered.
Does grey down have lower insulation performance?
Color alone does not establish insulation performance. Compare measured fill power, composition, fill weight and the finished product design.
