Bought 6 of these because I believed the reviews and the product description.. I don’t think these are bamboo because they don’t stay cool. The appearance of them are great.. but that’s the only good quality and I can’t return them because I got rid of the boxes they came in. Won’t be buying anything else from this company

Finally sleeping through the night without waking up drenched

I was dealing with night sweats almost every night. Waking up overheated, flipping my pillow over constantly, just uncomfortable and restless. It was starting to mess with my sleep in a real way. Since switching to this cooling pillowcase (and pairing it with a cooling blanket), it’s been a completely different experience. I’m actually staying cool through the night and not waking up soaked or irritated. The fabric feels cool to the touch right away and doesn’t trap heat like a regular pillowcase. It’s smooth, comfortable, and still feels good after washing. Not stiff or weird like some “cooling” materials can be. Is it magic? No. But does it noticeably reduce overheating and help you sleep better? Absolutely. If you run hot at night or deal with night sweats, this is one of those small upgrades that makes a big difference. I wish I had bought it sooner.

so far so good

I was surprised at this pair of pillow cases only because the material seemed impossible to be cooling - it's that weird polyester blend. So far I have not awoken feeling sweaty around my face and scalp. I don't recall what I originally paid but I think it is great value for money! If you are sensitive to out of the box smell, I washed mine first and it didn't impede on the efficacy of the cooling!
