Silky comfort
Color: Light Gray, Size: Full / Queen (90"x90")
I love this comforter. I’ve been using a blanket I ordered on another site for the last year that I loved but needed a new one because my son got bubble gum on it. I ordered this one after searching for a a couple of days. I was initially disappointed because it didn’t feel like it had the same cooling factor as my prior blanket. However, after sleeping with this blanket for the past 2 nights, I can say I’m in love. It’s still “cool”, just in a different way. I’m so excited to go lay down. Lol. It feels like a silk sandwich with light, soft comforter material on the inside. Silky and cool. Definitely recommend.

Excellent purchase
I love everything about it. The color, the soft cool texture and it drapes nicely over the sides of my mattress. It’s very beautiful. Perfect for the warmer season. I washed and dried it when I received it and it came out well. I love sleeping with it and so do my cats. A very excellent buy for little money

Perfect in every way!
We love this king size comforter. It is so soft and NO NOISE when touching or moving it around. It has just enough fill to keep us both warm. Just like we like it. We replaced this with one that was way to thick and way to heavy. This one is very high quality with good distributed fill in each pocket. We wanted to buy one for our grandsons twin bed, but unfortunately they only had Queen up to Cali King. He fell in love with how soft and warm it was, without being too hot also. It took about 6 hours to fill out from unpacking and it’s again perfect. Not paper thin and not aggravatingly thick either. Just right! Now I can watch TV while laying down in bed without having to move the comforter every 5 minutes.
We have had many all season comforters over the years from bargain priced to $400.00 ones and this is the best one ever. This price point beats the high end ones in every way. Get this I promise you won’t be disappointed. Excellent quality and comfort for the price. A true hidden treasure!

Snuggled up writing this review!
I love the weight, and puff to this lovely comforter! It does keep me warm, and I have NOT noticed any noise.. I'm not sure what others were talking about about. I love how soft but well made this is made! I recommend this if you're looking to dip your toes into a down comforter ...or just want to feel luxurious!
