Actually feels cool at night
Color: Light Gray, Size: Standard
I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.

Soft and smooth cover
Color: Grey, Size: Body（20"X 54"）
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body（20"X 54"）
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.

Very nice pillowcases
Color: Haze Blue, Size: 2 Pack Standard（20"X 26"）
Very pretty pillowcases. I washed them in cold water and dried them on low before using. They came out a little wrinkly but smoothed out on the pillow. The fabric is shiny and rich looking. It's not hot yet, here in Texas, but I am anticipating the coolness of these pillowcases to feel very nice. I appreciate the envelope closure. It gives it a finished look. There was no odd odor. They feel good like they'll last for a long time. I am a satisfied customer.
