Magic!
Color: Grey, Size: King (102" X 90")
This comforter is super soft. Almost silky feeling. Very easy to wash and dry. It does as advertised. It keeps me super cool. I love it so much that I bought a second one for my camp. It is so cool to the touch. The fit is true to size. It's not thick but not too thin either.

Best Sleep
Color: Light Blue, Size: King (102" X 90")
This comforter is perfect for summer sleeping! The material is soft and has a cooling feel to it all night long. It is just the right thickness for enough warmth. The blue color is lovely and looks great ! Highly recommended this comforter.

Bought this for my son and just ordered me one
Color: Grey, Size: Queen (88" X 88")
My son's college apartment runs warm (that is probably because college students trying to save money) so we decided to order him this cooling comforter. I have been wanting one since entering menopause but never bought one for myself (the things we will do for our kids but not ourselves) so when his came in I told him I was going to use it to see if I liked it and if it helped with the night sweats until we met up to give it to him...those three nights of me using it were enough for me to want one. This is a game changer! It is thin like a blanket so we removed the flat sheet and put this under our regular comforter. My husband needs the thickness of our regular comforter because he says I freeze him out at night. This 'comforter' is so soft, fits the bed great (as a blanket or comforter), and is truly cooling. Now, that's not to say I haven't woken up a little on the warm side but all I need to do is readjust to a cool spot under the blanket and I fall right back to sleep. The grey is very light but it is washable as needed.

Perfffff
Color: White, Size: Oversized King, Color: White, Size: Oversized King
So very comfy! I did not expect to love this as much as I do. I was worried about it being too hot. It’s not. I was used to sleeping with a quilt but this is so comforting, the weight of it is so cozy & perfect. I sized up with oversized king for my king size duvet cover. Its so fluffy and perfect for the aesthetic I wanted
