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.

The best Pillow ever!
Size: Queen (Mid Loft), Number of Items: 1
I am a life long latex pillow user! The one i typically use is 150+. This pillow is better and less expensive . It has just enough firmness but still soft . I am a side sleeper and it supports my neck perfectly . I am going to buy three more!
