Down is the naturally grown plumage forming the undercoating of waterfowl (goose or duck); A single down cluster consists of many light fluffy filaments growing from a central quill point that is naturally occurring and three dimensional in structure.

Nestling Down

Underdeveloped down made up of soft fluffy barbs radiating from a sheath, is called Nestling down. Nestling down does not have quills.


Plumage consisting of soft quills and barbs.

A group of components including down, nestling down and plumules.

Species Identification

Feathers and down are tested to determine what species of bird they come from.

Fill Power

Fill power is a measure of loft, or the insulation ability of down products in cubic inches per ounce. The higher the number, the more fill power there is.

Oxygen Number

Oxygen number indicates product cleanliness. Down and feathers are soaked and agitated in a solution of pure water, which is then measured for organic material. The lower the number the better, the cleanest samples measure 1.6-3.2, the highest number allowed is 10.


Turbidity helps determine if dust or dirt (organic and inorganic) is present in the down and feather. A sample of down or feathers is soaked and agitated in pure water, the water is then measured for clarity. U.S. and European standards require a result of at least 300 mm. Very clean samples register at 550 mm or higher.

Thread Count

The thread count is the number of threads per square inch of fabric, measured at least five times and then the results are averaged together. Two-ply yarns are counted as one thread and may not be used to double thread count. Generally, the higher the thread count is, the more down-proof the fabric.

Cleaning & Care Guide

Given the wide range of down and feather products offered in the marketplace today, consumers should always follow the manufacturer’s care instructions provided with the product.

If you plan on cleaning your down and feather products at home, make sure that you use a washing machine that does not have a center agitator, as this can damage the down pockets in your bedding, clothing, or outdoor gear.

To re-fluff your product, place it in the dryer on low heat with a few new tennis balls. The tennis balls will fluff the product as they tumble dry. This keeps the down and feather filling from clumping while it dries.

Please note, tennis balls have the ability to break zippers and buttons on garments, be sure to monitor closely.
