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.”

Technology

More than thread count, NASA-approved Outlast® fibers adapt to fluctuations in your temperature for an innovative approach to maximum sleeping comfort.

Tencel® fibers offer a silky smooth feel and moisture wicking properties for the most comfortable night's sleep.

Materials

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.

How does the technology in the bedding work?

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.”

How many degrees cooler will this keep me?

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.

What's the difference between Slumber Cloud bedding and other "cooling" bedding I might have tried?

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.

Does this come with one or two pillowcases?

The Performance Pillowcase Set comes with two pillowcases.

Is this machine washable?

Yes! Just like traditional bedding, Slumber Cloud products are designed to be washed and dried in your home washer and dryer. Please carefully follow the care instructions on the tag of your products.

Can I use an iron on my bedding?

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.

How do I sanitize my bedding?

Although we recommend against using high heat when washing your bedding there are products that can help with sanitizing your bedding. Here are a few of our favorites: Dropps & Tide

How should I remove stains?

Please refrain from using harsh chemicals such as bleach and oxiclean on your bedding. Instead opt for more natural alternatives such as a small amount of dish soap, a warm water & vinegar solution, or specialty formulated laundry detergent such as Dropps

How do I wash my Performance Pillowcase Set?

To wash your pillowcases, please follow the washing instructions on the tag. If you have cut your tags after purchase, then it is recommended to wash with Slumber Cloud Free & Clear Laundry Detergent or a mild detergent in cold water on a delicate spin cycle.

When it’s time to dry your pillowcases, please dry it on low heat or air dry. Do not iron your sheets. To reduce wrinkling, take your pillowcases out of the dryer and immediately place on your bed or use a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.

Is there a trial period?

Yes! We want you to love your new bedding. Sleep on it, wash it, and really put it to the test for 60 days! If you don’t love your new bedding, just return it free of charge for a full refund. No questions asked!

Can I still return an item even if it's been washed?

We accept returns in any condition within 60 days of purchase! We want you to absolutely love your new bedding, so if you wash an item, try it out, and decide it's just not for you, we can definitely still initiate a return.

Please note we do our very best to donate all returns to local charities instead of a landfill. We appreciate your help in this process by washing any used items before returning them to us.

Are your products covered by a warranty?

Yes! All of our products are covered not only by the 60 night trial period but also a 180 day warranty which covers manufacturers defects (i.e. stitching, sizing).

Please note in addition to damage caused by disregard of care instructions, temperature performance is not considered a manufacturers defect or covered by the product warranty.
