Yves delorme-Continental collection-The best down comes from geese that are allowed to grow to full size. We use only hand-selected mature white European goose down from free-range geese raised just for this purpose. Down is gathered in the molting season, when it has reached its full size and full potential to hold air. Why? Because large, mature clusters allow more air to be retained between the fibers, keeping you warmer. Small down clusters have poor filling power and tend to collapse after a few years because the filaments are more fragile.
