UltraCool 枕頭套

The zip is actually smooth and tucks away neatly, so you don’t feel a thing under your head. The cooling nylon/spandex fabric stays silky all night, and I’ve stopped flipping my pillow to the “cold side” entirely.

I was skeptical about the zip-over design, but it stays put all night and the spandex gives just enough stretch to feel custom-fit. My pillow actually feels cool to the touch when I lay down, which is a game-changer for summer.

The nylon fabric is noticeably cooler to the touch than my old cotton case, and the spandex gives it a nice stretch that stays put all night. I've been sleeping through the night without flipping the pillow over once.
