No More Flipping To The Cool Side

Even the hottest of sleepers can stay cool and comfortable all night long. With two layers of Outlast® fabric, these cooling pillow covers will help keep your head at the perfect temperature all night while complementing the other components of your Slumber Cloud sleep system.

Zippered Enclosure

It's never been easier to turn your existing pillows into "cooling" pillows. Simply zip the cover over your pillow for a NASA-engineered temperature control solution.

Protect Your Pillow

With the addition of the Core Pillow Cover you can extend the lifetime of your pillow. By adding an additional layer to your pillow this will reduce the direct wear and tear of your pillow and make laundry day a breeze.

Why It's Different

Most companies that claim to have cooling, sweat-wicking bedding only attempt to manage temperature once you've already become uncomfortable. Slumber Cloud is doing something different.

Slumber Cloud Bedding utilizes Outlast® technology for a proactive, not reactive, approach to temperature regulation. Outlast® technology regulates heat to stop moisture from developing in the first place, instead of attempting to wick away sweat that has already developed.

Not too hot…not too cool…just right.

The Single Pack option comes with one pillow cover. The Two Pack comes with two pillow covers. That means one for you and one to share with your partner (or not share, we don’t judge).
