We’ve Got You Covered

Pushing and pulling at the covers is typically a result of humidity developing in your beds microclimate, a.k.a the space between your mattress and your top cover. To stabilize humidity and reduce sleep disruptions, the Stratus Duvet Cover employees the moisture regulating power of Outlast® technology infused in a soft and breathable 300 thread count 40% Outlast® viscose, 60% sateen cotton cover. The end result is the softness and durability of cotton, plus the breathability and temperature regulation you find in the most luxurious duvet covers.

Engineered to prevent overheating and sweating while you sleep, this layer of the Slumber Cloud sleep system elevates the look and feel of your entire bed while protecting your duvet or comforter from the elements.

Humidity

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.

WHY WE USE OUTLAST® TECHNOLOGY

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.
