Our Laurentian duvet is filled with top quality white down taken from geese and ducks that live in northern Canada, in the open air where temperatures often go from -50°C in winter to 35°C in summer. Because of this temperature range, the birds have had to adapt themselves to the changing climate, and thus produce some of the world's finest down. With its 600 cu.in/oz fill power, this down gives our duvet amazing volume. Coupled with our down-proof casing, this duvet is a quality addition to your bedroom. The 100% cotton casing,  with a 233 thread count, will bring you softness and comfort throughout the night, all year long. Made with several compartments, our Laurentian duvet design guarantees an even distribution of down within the duvet and the uniform warmth expected from a Canadian down duvet. Our duvet is thermo regulated, meaning it will reach and maintain your body temperature no matter what the ambient temperature is. This hand sewn duvet is filled with luxurious white down, carefully selected and fluffed in our facilities for your comfort! Our Laurentian duvet is hypoallergenic and has received our Ultra Fresh treatment, which inhibits the growth of bacteria, mould and mildew. We recommend the use of a duvet cover which will ensure the protection and longevity of your down duvet.
