Down Comforters

In our discussion about fill power and loft over the past several days we would be remiss if we did not say that calculations are only approximate. A more accurate way to compare goose down comforters is to use European Norm temperature ratings, which are based on realistic independent lab tests.

 These tests are the lowest comfortable temperature, and go above a safe but not comfortable temperature. In the United States, sleeping bags have temperature ratings, but manufacturers do not use standardized methods in establishing temperature comfort ratings.
