Light and cooling
"I really like the new comforter as it does keep me cooler at night and yet is lightweight. It’s a little slippery so it can slide around a lot on the bed. Overall a good product. I’d buy more if it went in sale"

These sheets and duvet cover are so comfy and cozy! They really do keep me cooler at nights too; which I've been fighting with my entire life - I'm an overheater! I already recommended them to my best friend.

Perfect for California Summer! I love the lightweight and how well it regulates heat, so that we are not hot nor cold. It is perfection. I was hesitant because of the cost but glad that I decided to purchase it

I have bought countless pillows, new bed, different positions, tried couch, bought new couch. Got this ultra cool pillow, so soft, literally feels like sleeping on a nice cool cloud. Slept the full night, first full night in over a year.

Reviews
Excellent quality but expensive
"This comforter is super soft and well made. It does keep me cooler than my previous comforter, but I still wake up hot at night. I was hoping for better results. The material is cool to the touch. It doesn't wrinkle that much which I really like. It looks great even without a duvet cover. I got lightweight option in white. Its a true white."
Comfortable but no effect on temp
"This comforter is very soft and cool to the touch. However, I haven’t noticed any difference in temperature throughout the night and no change in my nightsweats. It’s a premium price tag for a blanket that performs the same as cheap blankets"
Works perfect!
"I bought the slumber cloud comforter because in the summer the upstairs of my townhouse gets about 10 degrees hotter than the downstairs. Even with air conditioning. It's cool to the touch, easy to wash and dry. I highly recommend for anyone in my situation, or that sleeps hot etc."
Wonderful product
"Cool to the touch, drapes beautifully. No clumps whatsoever. Paired with a percale duvet and sheets and I'm sleeping much more comfortably. Highly recommend!"
Definitely not cooling. I think
"Definitely not cooling. I think I get hot during the night and throw duvet off more often now. I do like the thin clean look of it."
Best soft cooling comforter
"I have tried several cooling comforters. I love this one! Comfortable all night"
Don't think about it, buy it!
"Ordered this after reading all the reviews and honestly, I’m impressed. My partner is a really hot sleeper, so finding a blanket that works for both of us has been tough. We sized up and got a king for our queen bed, and it’s been the best decision. It's comfortable and breathable."
Comforter
"We love this cooling comforter! It works great!"
"MOST AMAZINGLY SOFT AND COOL comforter of my life!! HIGHLY RECOMMEND! Life changing!"
