What it is: Small, soft inner feathers from the breast of the female eider duck, a large seabird that inhabits the northern coasts of Europe, North America and eastern Siberia
Value: About $330 a kilogram. It takes about one kilogram of eiderdown to make a cold-weather parka.
Why it's so expensive: Rarity. Entire world production is between four tonnes and five tonnes a year. Considered the warmest and lightest insulation anywhere. Doesn't retain moisture and maintains shape and even distribution when used in duvets and clothes.
How it's collected: By hand, from nests with eggs in them. Harvesters must leave at least half the down in the nest.
Economic impact: Feasibility study predicts the Sanikiluaq factory could generate a $200,000 profit by third year. Ten to 15 full-time jobs. Supplementary income source for hunters on the land.
