I have a stay cool pillow and it works so well with these cases, I stay so comfortable all night long and I absolutely love it, I love that it has the extra pice on the inside that keeps my pillow in the case, that makes such a world of difference, with my old case I was always putting my pillow back in, now I just get to lay down and go to sleep and they look great with the colors of my room. I love the silky feel of them, it makes me feel like a queen.
