Then let’s get down to basics! The most important part of a down comforter is the quality of its fill which should be 700 or 800 fill weight for the lightest, fluffiest, and best insulating down. The next important feature is the quality of manufacture and we recommend box baffling to make sure the down has enough room to remain lofted but does not shift around. For allergy sufferers, the cleanliness and hypoallergenic properties of the down is paramount, and the Hypodown Collection does it better than most because it introduces a tiny amount of Syriaca into the down, which in turn enhances its hypoallergenic properties. You do not need the most expensive covering; this comforter will last more than a lifetime if given proper care and that means putting it into a duvet cover so it is protected. For most people the Monarch covering is the most effective choice since it is soft and supple.
