Review on Elegear Cooling Pillow Cases For Hot Sleepers, Japanese Q-Max 0.45 Cooling Pillowcases, Both Sides[Cooling/Cotton], Breathable Soft Pillowcase For Hair And Skin, Set Of 2-Gray (Queen (20'' X 30'')) by Amy Ruiz

These pillow cases aren't bad at all.

The material for the cooling side is very comfortable, and seems to perform about as expected for the price.I do sorely wish the cooling material was on both sides though, so flipping the pillow for a fresh side was easier. The non-cooling side just doesn't have much value to me - it's the exact opposite of what I want, the material is warmer than regular cotton/bamboo thread sheets, which isn't particularly helpful for me.I'd still recommend these, just know what you're getting - if the warm side would also be useful to you, these are a high-quality buy for the price for sure.
