Exceptionally high quality down for a soft, airy & warm duvet A stunningly soft, airy duvet with unbelievable insulation properties. You only get a duvet this good when it's filled with 100% premium goose down, which is why we've sourced the down for this duvet from a Hutterite community in Canada providing us with this incredibly high quality down. We've added to its airy feeling with a super fine & light 400 thread count cotton casing. For a product of this quality, authenticity is essential; Soak & Sleep is (since 2013) an associate member of the Down Association of Canada. This Supreme Canadian duvet carries the Downmark to let you know it's the real thing.
