Goose down is the soft, light, fluffy undercoating of the goose. It is a superior fill to duck down or feathers because it offers large clusters that fluff up or “loft” to product better insulation. There is no difference in quality between white and gray goose down; however, white is usually preferred since it does not show through the duvet shell. When shopping around, unless a duvet is specifically labeled “goose down”, it is probably duck down.
There is a wide variety of down and feather blends for various purposes and budgets. Generally, the more down, the softer and fluffier the duvet. The more feathers a duvet has, the firmer and springier it will be.
Synthetic fibers are ideal for people allergic to down. These innovative synthetics are more like down than ever before; they simulate the softness, fluidity, and loft of down because the fiber is formed in small individual clusters.
What a great idea. Thank you for this insight.
Glad you liked it.
