FAQs

Although both pillowcase options are designed to help you sleep cooler and more comfortable, it's important to choose the version that best suits your sleeping needs. Below is a quick overview of each option to help you in this decision making:

Essential Pillowcase:
The blend of cotton and Outlast® temperature-regulation viscose fibers offers a traditional super soft cotton feel. Ideal for those who prefer a more classic sheet but want temperature-regulation performance.

Performance Pillowcase:
The blend of premium Tencel® and Outlast® temperature-regulation viscose fibers offers a buttery, silky performance feel. Ideal for those who prefer silky smooth softness with the most temperature-regulation performance.

Slumber Cloud products are designed to help manage heat and humidity build up. It is not an air conditioner with a set temperature degree, but it will react to your temperature all night long to reduce heat build up and manage temperature swings.

The premium fabric has a super soft cotton hand-feel, with a slight cool touch.

The Essential Pillowcase Set comes with two separate pillowcases in a set.
