This comforter has to be able to keep us toasty during the extra cold winters here in Colorado. When I took it out of the bag, I was concerned, as the comforter was quite thin! We are used to down comforters that are usually quite thick, fluffly and heavy. The first night with the new comforter, we reserved several blankets at the foot of the bed. We were pleasenly surprised that no other blankets were necessary. We stayed toasty all night! It says on the package that it can be used in warm weather, as well. We will await spring with anticipation!
