Best pillowcase ever
Color: Stormy Grey, Size: Standard
I bought these awhile ago and they have been by far my favorite pillowcases. They are worth the money. They have been through countless washes and you can’t even tell. They are cool to the touch and while they warm up a little during use they never get uncomfortably warm. They are so soft and feel great on my face. They don’t slip off the pillow as easily as my other pillow cases. I definitely recommend!

nice feel, but sleeps warmer
Color: Deep Purple, Size: King
The stretchy material does conform with the pillow more nicely than other pillowcases, but unlike other bamboo linens, I found it a much hotter material. I'd reserve this for fall/winter sleeping.

Soft and Comfortable
Color: Deep Purple, Size: Standard
My husband absolutely loves the purple pillowcases. He likes the extra length, the good quality and the softness. It could definitely fit a larger than normal pillow and has good stretch to it.

Perfect pillow case
Color: Stormy Grey, Size: Standard
Amazing stretch fabric. Nice color. Covers my purple pillow which is a queen size but, does not fit regular queen size case. I could have used a king size case but thought I would give these a try and it works. If you are on the fence, give these cases a try. I love my pillow even more now.

Soft, moisture wicking
Color: Stormy Grey, Size: Standard
Super soft pillow cases, very nice against face. They are also moisture wicking and dont seem to hold heat. My new favorite brand of sheets/pillows/pillowcases and maybe one day a bed.
