As you repeatedly reverse and scrutinize this silk comforter, you'll see that the luxurious silk comforter is soft, luxurious, free of loose threads, and folds up very easily. When you toss the comforter into the air by grabbing one of the sides, the comforter seems to fall slowly as if it could fly through the air. This comforter has a premium cotton shell and is filled with the highest grade of 7A mulberry silk. The natural breathability of silk wicks away moisture and keeps the comforter at a comfortable temperature for a restful night's sleep.
