Stay Instantly Cool All Night
Crafted with Arc-Chill 3.0 fabric (Q-Max > 0.5), this cooling pillowcase absorbs body heat and lowers skin temperature by up to 9°F, keeping you in the ideal 77°F sleep zone—perfect for hot summer nights or air-conditioned rooms.

Freshness That Lasts
Infused with silver ions, it resists odors and stays crisp night after night. Skin-safe and OEKO-TEX certified, it’s ideal for sensitive skin, including babies.

Featherlight & Ultra-Breathable
With a seamless, single-layer design, this pillowcase is thinner, softer, and cooler than traditional covers. Dual-sided cooling fabric offers all-night comfort at home or on the go.

Thoughtfully Designed
The hidden zipper prevents irritation and protects your face from hardware. Its stretch fabric and wide opening make it easy to fit most pillow sizes and swap out covers.

Easy Care
Machine washable and stays cool after every wash. Simply air dry or tumble dry on low (below 86°F) for lasting freshness.

Perfect Gift for Hot Sleepers
Cool, clean, and skin-friendly—an ideal gift for summer comfort.
