1. Pay Attention To The Down Ratio
The proportion of down in the duvets / eco comforters is directly related to its hygroscopicity and thermal insulation. The proportion of goose down as high as 90% is of high quality, with high elasticity and fluffy feeling, and has very good warmth retention; up to 95% or more of goose feather down is regarded as the highest quality and the most comfortable and warmest type of duvet / eco comforter.
