Innovative Cooling Technology

Woven in a slick, silky jacquard weave, our exclusive Lulltra™ Cool fabric is 1.5 times denser than our standard fabric. At 400 gsm, this heavyweight fabric maintains a cool and comfy feeling while wicking heat away from your body throughout the night.

No Additional Case Required

Because of our fabric’s specific qualities, we suggest you sleep directly on your Cool Side Pillowcase. Plus, the modern jacquard pattern, neutral grey piping, and hidden zip closure make it perfect-looking on its own.

A Cost-Effective Solution

Cranking the A/C isn’t great for your bills—or the environment. By instantly cooling your head and neck, you’ll be able to fall asleep faster and dream of Christmas in July. Plus, the Cool Side Pillowcase enables you to get the comforting and supportive benefits of memory foam without all that heat.

Surprised

I didn’t think it would work but it has allowed me to use my old pillow more comfortably. You have to keep shifting it because where your head is will heat up.
