What exactly goes into our bedding? Have you hear of Outlast Technology? We use Outlast Technology to create a microclimate, helping you stay warm and cool.

We get a lot of calls about  how our products cool and what the majority of our customers are suprised to hear is that the technology we selected to help keep you cooler at night also helps keep those cold sleepers warmer. So in the winter months, you can rest assure that your heat will be managed to keep you at an optimal sleeping temperature. Not too hot, not too cold, but just right.

So what is Outlast technology?

Outlast® was originally developed for NASA to help with the temperature fluctuations in space. It  utilizes phase change materials (PCM)  that absorb, store and release heat for optimal thermal comfort.  A phase change materials you probably see or use every day is ice. Think of  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 so it won’t leak onto you as you sleep.  It  is protected in a polymer shell that is micro in size (there are approximately 10,000 can fit on the head of a pin).   Outlast calls these microencapsulated phase change materials Thermocules™.  

Don’t you feel smarter already?   You learn something new every day!

The Process

This encapsulation process makes the Thermocules™ exceptionally durable and gives the Slumber Cloud products containing Outlast® technology the ability to continually regulate the skin’s microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.   So it works for both hot and cold sleepers and can be used in all 4 seasons. How cool is that?… or should I say: warm?…  (Ok, pun was intended and it wasn’t very funny…)

Need a cool science project for your kids/grandkids?  Have them do a project on phase change materials.  They can display different phase change materials such as ice, candles, chapstick, butter, and we can send you a vial of Outlast to show how they all absorb excess heat (Melt) and release excess heat (solidify) when temperatures change.  It’s FUN, and I’m sure they would get an A!
