Cool with Caveats
First, these feel cool when you take them out of the packaging. They're soft, and comfortable, but there's some method to enjoying them. They seem to be at their coolest in a cloth-on-cloth scenario. If you're someone who sleeps only in your boxers, they feel cool, but humid. If you put even a tank-top on that changes., and you feel cooler than if you'd slept without a shirt. I'm giving it five stars because after I discovered that hack, they've provided the best sheets I've had for summers.

Cold, Silky, & Smooth
These sheets are such a unique material! They are super silky, stretchy, and cool to the touch. The "Cool Meadow" color is perfect. As soon as I put them on my bed, I "snow angeI'd" on them for a solid 10 min because they felt so glorious on my skin hahah. I legitimately ordered a 2nd set immediately after I laid on them.
The oversized sheet is perfect for my extra deep bed - they are the first ones I've ever had not come off on the corners between me, my bf, and my 55lb dog. You will definitely need to tuck the top sheet in because it does slide around a lot.
While I still found myself sweating at times during the night (it's my medication's fault, not the sheets!), and they obviously get warm where you are laying from your body heat, I just move an inch to either side to get to a new cold spot (there is no better feeling). They have also held up to my dog's nails, and don't collect hair either!!
I haven't washed them yet, but I am confident they will remain in great condition if I follow the proper washing instructions.
