 "I live in Arizona and run super hot at night. I was literally flipping my pillow every 20-30 mins to find the cool side. This pillow ACTUALLY stays cool the entire night, not just when you first lay down."

 "I'm a side sleeper and have always struggled with pillows being either too flat or too thick. This pillow is literaly perfect. The height is just right so my spine stays aligned and I dont wake up with shoulder pain anymore."

 "As someone who trains 6 days a week, recovery is everything. I track my sleep on my Whoop and my sleep quality scores went from averaging 68% to 89% after switching to this pillow. Never thought a pillow would impact my performance but here we are."

Stop sleeping on wrinkled, baggy cotton. We engineered the AeroFlex Pillow Case with a proprietary 4-fiber blend that combines the softness of luxury bedding with the fit of high-performance activewear.

Why it feels different:

☁️ The Perfect "Snap" Fit: Thanks to 6% Spandex, this case stretches to custom-mold around the unique curves of your Onyx pillow. No bunching, no wrinkles, just a smooth surface every time.

❄️ Zero-Heat Retention: We blended 24.3% Beechwood Modal with premium Cotton. This combination is 50% more absorbent than cotton alone, pulling sweat away from your skin instantly so the "cool side" of the pillow is every side.

✨ Hotel-Grade Smoothness: The Modal fiber provides a silky, high-end glide that reduces friction on your hair and skin, preventing sleep lines and morning frizz.

The Fabric Specs:

Feel: Silky-smooth, cool-to-the-touch, slight stretch.
Fit: Taut, wrinkle-free, contour-hugging.

Product Details:

Certifications: OEKO-TEX® Standard 100 (Safe from harmful substances)
Care: Machine wash cold, tumble dry low.
Compatibility: Designed exclusively for the Onyx Aeromatrix™ Pillow.
