Outlast Technology

The Cool Side

Infused with a heavy coating of space aged Outlast® technology, the 300 thread count, 100% cotton outer shell keeps your head cool by absorbing, storing, and releasing heat as your temperature changes throughout the night.

The perfect complement to the other layers of your Slumber Cloud sleep system. Rest your head on the pillow designed for the best sleep ever by keeping your head supported and at the perfect sleeping temperature.

Out of this world comfort

Truly born from space, Slumber Cloud bedding is infused with the same temperature regulating technology NASA astronauts used in their spacesuits. This patented technology, called Outlast® technology, is made up of thousands of microscopic “beads” called Thermocules™. Each individual bead is set to a specific temperature to counter any temperature fluctuations you might experience during the night. As your temperature increases, the beads absorb and store any excess heat away from your body to keep you cool. If your temperature drops, the beads release the stored heat back to you to keep you at the perfect temperature. The end result is a better night’s sleep with bedding that helps you sleep more comfortably, sweat less, and wake up feeling refreshed.

Outlast Space certified


Cools Hot Sleepers

It’s just plain frustrating to keep waking up night after night, soaked with sweat and unable to get back to sleep. Many people of all ages and body types suffer from night sweats. Outlast® technology keeps you at the most comfortable temperature throughout the night… so you sleep cooler and more comfortably.

Helps With Hot Beds

Love your bed, but not all the heat buildup? Although they can reduce pressure points, beds with memory foam often get uncomfortably hot. Outlast® technology helps prevent the heat from your mattress from building up. You'll still enjoy the comfort of your mattress but without that hot, sweaty feeling.

Controls Humidity

When humidity develops in your bedding, your body sweats raising the humidity even higher. This causes you to wake up and push the covers off to "release" the humidity. Later you wake up again, this time too cold without the covers. Outlast® technology mitigates heat and humidity so there's no more pushing and pulling at the covers.

The Right Stuff

The backbone of the Cirrus Pillow’s construction is the inner fiberfill. Filled in the USA, the filling inside our pillows provide your head with the prefect amount of support that bounces back to life with just a quick fluff. With two fill types and 3 firmness levels to choose from, it’s easy to pick the perfect pillow for your needs. We recommend soft for stomach sleepers, medium for back sleepers, or firm for side sleepers.

American duck down

American duck down fill creates an adaptive, liquid-like feel that responds to your movements through the night. This natural fiber is resistant to clumping, meaning it can bounce back to life with just a quick fluff.

Polyester fiberfill

Polyester fill fortifies the pillow’s shape and evenly distributes the fill, creating a consistent loft. It also provides optimal neck support for better spine alignment.
