Slumber Cloud Outlast Performance Pillow Covers - King (Pack of 2)
Turn all your pillows into cool pillows. Extremely lightweight and airy, these covers stay cool without changing the feel of your pillow underneath. Ultralight and breathable construction combined with NASA-approved temperature regulating technology and moisture wicking fabric add up to a cooler night's rest.
Technology: Outlast technology is a unique material capable of maintaining and regulating your temperature. As your skin temperature increases, the technology absorbs heat, then releases it when your skin temperature drops, so you sleep "just right."
Our premium lining fabric takes a proactive approach by employing active temperature control properties, versus other "cooling" bedding that is moisture-wicking and simply reactive.
Tencel fibers offer a silky smooth feel and moisture wicking properties for the most comfortable night's sleep.
Outlast materials improve comfort for:
Anyone looking for a more comfortable night's sleep - they'll sleep cooler!
Women experiencing menopause - hot flashes and resulting night sweats are reduced so they sleep cooler and drier.
Thermally incompatible couples - individuals sleep at their own ideal temperature
Research: We pass on everything we learn to our customers. From sleep studies to new technologies, we want to help you make informed decisions about your sleep.

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.
