After putting this on my bed, covered by a light weight quilt, the temperature tumbled to 6 degrees. I was warm and toasty. Presently the night time temps are around 32 degrees and sleeping under this down blanket are just as comfortable. I love the fact that this down blanket acts just like a regular blanket. You can tuck the bottom in keeping the blanket where it should be and not slipping off on the floor. I would recommend this to anyone looking for an inexpensive down blanket
