compared to REST pillow cases this is a fantastic way cheaper comparable item.
Color: 02 - Blue, Size: King(20x36)
I always run hot and especially when I'm sleeping. I'm also a snob when it comes to my sheets, I normally but REST which is amazing and cooling but so freaking expensive. I had bought a few REST sheets but unfortunately after my maid would leave I had lost quite a few of my sheets. I do not want to pay 65 dollars for just pillow cases so I bought these to match my blue REST not really expecting much. THEY ARE AMAZING FOR 20 BUCKS!! So soft, cooling and they have a zipper. the quality is pretty close to REST's pillow cases! I will buy again!

It’s you’re a hot sleeper - hurry and buy this pillow case !
Color: 03 - White, Size: Queen(20x30)
If you’re a hot sleeper ! This is the pillow cover you want!!!! Don’t hesitate to buy. I love how it has the zipper to it so the pillow doesn’t come out. Appearance is beautiful. Softness is rate 11 out of 1-10z. May wrinkle after wash a bit but once place on the pillow wrinkles go away. Great for your hair because of the material great value for your money.
