850 / 800 Fill Power Goose Down
From the best sources in Eastern Europe we have cornered the market on some really old birds, the Mother Goose. These geese are used for the farmers’ personal food supply and are much older than the geese normally raised for market. Avg. age is 1-3 yrs. And these big honkers make mean old’ watch geese too.
Older geese produce mature down with larger, stronger and longer lasting down clusters. Many high fill power downs are mostly highly processed Chinese down with high cluster % but from younger Chinese birds that will not maintain loft over time. The difference in 850 fill is the selection of only the best of the best and the careful processing to assure the finest down available.
