This Silk Camel comforter lives up to the reputation! The silk type Mulberry down is very light weight, however, this keeps one cool when temperature is too warm and keeps one warm when temperature is too cool. Yet, it is so very lightweight. I was skeptical but so glad I bought it. It can never be washed nor dry-cleaned, so a good Duvet cover is a must, and I think the Duvet COVER must be cleaned once to twice daily.
