"I had bought this product along with the cover for it. After the first night, Cover already started slipping out of place. Considering that this is a $600 bundle, it should not feel broken after just one night. In the description for the duvet, it says that it shouldn’t bunch and stay fluffy. That is an absolute lie. I’m very disappointed and will not be buying another one again."
"The size is off. We have the king size comforter and it is not properly sized if you use it with a duvet cover (even the Casper ones don't work). After reaching out to Casper, there's nothing they can do. Now we have a comforter we cannot use because it bunches up in the cover, even with corner ties. Waste of money"
"Does not work as advertised. Nightmare return process"
"Absolutely hate it. I opened the packaging, the material is hard and crunchy and feels like paper so I never used it, put it straight back in the box. Attempted to return this unused product within the 30 days as stipulated on the website and they’re saying because the box was opened it’s not eligible for return, even though there is no mention of that in the return policy on the website. How are people supposed to know if the product is right for them if they can’t see or touch it? Stay away from this duvet, it’s terrible quality, thin, noisy, and scratchy."
"Living in Hawaii, the Humidity Fighting Duvet is great! There's no SMELL."
"Got it in the store and it's really warm and lightweight! It should be enough for a Washington state winter with heating :)"
"You won’t be able to find a duvet cover to fit it, not even the Casper one."
"I own the previous version of the Humidity Fighting Duvet, which I can only assume is equivalent to the mid-weight revision, and it's very warm. It's currently winter, and I leave my window partially open at night so my room temperature typically ranges from 10 to 15 Celsius. Unless it is at the lower end of that range, I wake up very hot, sweating, and often need to uncover to cool down, fortunately my room is cold so it doesn't take long. I do use a linen duvet cover."
"Great product, its very warm but also helps with night sweats. I am a fan!"
"Came just in time for the cold weather and it really keeps you warm and cozy all night. Definitely doesn’t overheat."
