Why You'll Love It:

A cooling comforter that can be used all year long.

NASA-Engineered Comfort

The patented ClimaDry™ by Outlast fiberfill proactively regulates heat and moisture by absorbing, storing, and releasing heat.

Lab Proven Results

One of the highest Qmax values on the market (higher Qmax values = higher coolness feeling) - better than cotton, bamboo, silk, and lyocell.

Silky Soft Comfort

Featuring an 89% cooling nylon and 11% spandex outer cover, the UltraCool Comforter mimics the feeling of silk.

Why It's Different

Most companies that claim to have cooling, sweat-wicking bedding only attempt to manage temperature once you've already become uncomfortable. Slumber Cloud is doing something different.

Slumber Cloud Bedding utilizes Outlast® technology for a proactive, not reactive, approach to temperature regulation. Outlast® technology regulates heat to stop moisture from developing in the first place, instead of attempting to wick away sweat that has already developed.

Not too hot…not too cool…just right.

FAQ

The UltraCool Comforter uses a premium outer cover fabric meaning pairing the UltraCool Comforter with a duvet cover is not necessary for temperature-regulation performance.

If you would prefer to use a duvet cover with the UltraCool Comforter it will regulate your temperature even when placed inside a duvet cover.

Definitely! When you sleep hot but your partner sleeps cold we refer to this as being “thermally incompatible”. Our bedding is designed to automatically adjust to each sleeper’s ideal sleep temperature. With the unique ability to react to each sleeper's temperature independently, our bedding ensures that both you and your partner will sleep comfortably all night long.

Although all three comforter options are designed to help you sleep cooler and more comfortable, it's important to choose the version that best suits your sleeping needs. Below is a quick overview of each option to help you in this decision making:

UltraCool Comforter: A more traditional weight, the UltraCool Comforter pairs Outlast® temperature-regulation fiberfill with silky smooth outer fabric that is made of cooling nylon and spandex. The UltraCool Comforter is designed with 300 gsm fill weight – that of a traditional 3-season comforter but without the traditional heat build up. This comforter is the ideal choice for year-round use.

Lightweight Comforter: Our most popular comforter, the Lightweight Comforter uses Outlast® temperature-regulation fiberfill to regulate heat and humidity build up. Our thinnest option, this is best suited for "hot" sleepers who still want a little bit of weight on top of them.

Comforter: A twist on a classic comforter, this 3-season Comforter uses Outlast® temperature-regulation fiberfill to regulate heat and humidity build up. With a higher fillweight than the Lightweight Comforter the Comforter is ideal for those who need more of a 3-season weight or who prefer a bit more loft.

Yes, the UltraCool Comforter comes with cover loops.
