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.

Body pillow covers
Color: White, Size: Body(20"X 54")
I ordered the body pillow covers. They fit my pillow perfectly and the fabric is smooth and silky, but I did not find them cooling.

Cooling King-Size Pillows (used on a Queen pillows to tuck the extra in)
Color: Navy Blue, Size: 2 Pack King(20"X 36"), Color: Navy Blue, Size: 2 Pack King(20"X 36")
🛏️ Product Review: Cooling King-Size Pillows (used on a Queen bed) ⭐ The Good • These are king-size pillows, which I actually love on a queen bed because I can tuck the ends into the fabric. • The fabric feels slick and cool, but you don’t slip off of it. • They feel cold to the touch right out of the package (which is wild). • I sleep extremely hot and even run fevers at night due to a medical condition (literally 101–102° sometimes), and these pillows still stay cool where I lay my head. • I’ve honestly never slept this well in my life. • For the price, you cannot beat them, and they go on sale often. • These beat any high-end version I’ve tried. • If you sleep normal-temp and not lava-hot like me, you’re going to be VERY comfortable with these. ⚠️ The Bad • The fabric does show crease lines. • If wrinkles bother you, this might annoy you (doesn’t bother me personally). 🔧 What I’d Change / Tips for Care • Don’t use fabric softener — it clogs the cooling fabric and ruins how it works. • Wash with unscented detergent + a little vinegar. • Dry on low heat only (do NOT dry on high if you want the fabric to keep working long-term). ✅ Final Thoughts I will literally never not own these again. If you sleep hot, night-sweat, or just want a pillow that actually stays cool — these are it. 10/10 recommend.

Love it but it stains
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
I love these but had to knock some stars down for a single reason. They are soft, the material is somehow both substantial and airy at the same time, and a smooth, silky (not satin), cozy texture. The color was exactly as pictured. The envelope style works great to keep my pillows covered. The fabric lays perfectly. I love sleeping on this pillow case. Took two stars off because every single atom of oil on my face stained it immediately and won't come out in the wash. Its not subtle. You can see anywhere my face has been, forever. I don't have some incredibly oily face or hair, I've never had this happen to another pillow case in my life.
