I bought the silk comforter with silk cover a while back. It’s so good that I have to purchase another one and this time I tried the one with cotton cover. They are my winter must haves. Because it’s extremely light weight, I was skeptical at first whether it will keep me warm at night. In less than a minute after wrapping it around me, I feel my own body temperature cocooned inside the comforter. It keeps me warm all night and I can’t sleep without it. I strongly recommend both comforters, especially for people who get cold easily and do not want to wear too many layers to sleep.
