This is a perfect lightweight summer duvet. The silky modal fabric shell is cooler than cotton, and the filling of 56% silk and 44% viscose makes it a bit lighter and cooler than my 100% silk-filled duvet, too. I use it inside a bamboo viscose duvet cover, and it keeps me warm enough at night not to be cold, and cool enough to sleep in in the morning for awhile without overheating. I have two small complaints - the king size is small for a king and does not completely fill out my king-size duvet cover, but the measurements are listed, and the little embroidered flowers that are stitched on here and there to hold the fill in place can be felt through my duvet cover and are a little annoying. I am going to see if I can carefully remove them without damaging the stitching. But I still give this five stars for the quality of the product and the reasonable price! I'm considering buying it in the queen size too!
