While many believe Icelandic eiderdown to be the best due to Iceland being the primary source of global eiderdown, this notion needs to be more accurate. The Common Eider Duck, which produces eiderdown, remains consistent whether nesting in Iceland or Canada. Some might think that because Iceland is colder, its eiderdown must be superior. However, this is different. The St. Lawrence Estuary in Canada, where we harvest our eiderdown, generally experiences colder winter temperatures than Iceland. So, if freezing temperatures were an indicator of eiderdown quality, Canadian eiderdown could arguably be seen as superior. That said, cold temperatures haven't directly impacted eiderdown quality. The Eider Duck simply has a preference for colder nesting climates globally. Considering everything, the Canadian Eider Duck offers some of the world's finest eiderdown. Our warm regards to our Icelandic counterparts.
