This product features cooling pillowcases made with upgraded double-sided cool fibers (Q-MAX 0.5) that absorb and release body heat for long-lasting comfort in heat. Infused with Nanotex technology, they wick moisture, dry quickly, and include 10% spandex for a silky, cool touch while resisting static to keep hair smooth and skin healthy. The double-sided jersey knit fabric adds a cloud-like, ultra-soft feel. Comes as a 2-pack with 3 sizes/colors; trusted by SLEEP ZONE (40+ years in bedding). Designed with a zipper and wide opening for easy wear, they’re machine-washable (cold, gentle cycle) and quick-drying (tumble low or air-dry).
