Why we're different.
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

Most frequently asked questions.
Outlast® technology is made of a unique material that can absorb, store and release excess heat. As an individual’s skin temperature increases, the technology will absorb that excess heat to help reduce overheating. The material will store the excess heat until the skin temperature begins to drop. When this occurs, the stored heat is released back to the individual to prevent chill.
By managing the build-up of heat and moisture under the covers, Outlast® technology helps keep you at a comfortable temperature so you sleep “just right.”
Slumber Cloud products are designed to help manage heat and humidity build up. It is not an air conditioner with a set temperature degree, but it will react to your temperature all night long to reduce heat build up and manage temperature swings.
Slumber Cloud takes a proactive approach to temperature control by absorbing and storing excess heat when temperatures are too warm and releasing heat when temperatures are too cold. This approach is different than most other "cooling" bedding technologies/products on the market that are moisture-wicking (ex. Bamboo & Eucalyptus).
Moisture-wicking is a reactive approach because it doesn't start to cool you down until you build up sweat and moisture and then wicks it off of you. Our products are designed to prevent you from ever getting to the point of sweating and building up moisture.
The technology in our bedding is sensitive to high heats - instead of ironing we recommend using a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.
Although we recommend against washing your Silk Pillowcase there is a product that can help with sanitizing your bedding: Tide
To wash your Silk Pillowcases please take follow the washing instructions on the tag. If you have cut your tags after purchase, it is recommended to hand wash with cold water using a pH neutral liquid detergent and/or fabric softener. Line dry. Do not tumble dry or iron.
