Why we're different.

Traditional bedding and moisture wicking technologies react to changes in your body temperature while you sleep. Slumber Cloud is doing something different. Slumber Cloud Bedding utilizes Outlast technology for an unmatched approach to temperature regulation. Outlast technology is proactive, not reactive. As your body temperature increases during sleep, Outlast technology stores that heat to keep you cool, and then releases it as you cool down keeping you feeling "just right".

The thoughtfulness is in the details 

It doesn't stop at thread count. It's the little things, the thoughtful details, that make our products the best available.

Outlast technology, originally developed for NASA, utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort. Outlast technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for longer. Outlast phase change materials work in the same way, but are microencapsulated to be permanently enclosed and protected in a polymer shell. We call microencapsulated phase change materials Thermocules.

This encapsulation process makes the Thermocules exceptionally durable for many applications. These Thermocules can be incorporated into fabrics and fibers and have the capacity to absorb, store and release excess heat. This gives any product containing Outlast technology the ability to continually regulate skin's microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.

Outlast technology is not wicking technology, which manages moisture by reacting to your sweat and pulling it away from the skin. Outlast technology will proactively manage heat while controlling the production of moisture before it begins. That's the Outlast difference.
