FAQs

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.

Our comforters are designed to regulate your temperature even when placed inside a duvet cover. Feel free to use a duvet cover to get the finished look you are after as it will not have a drastic impact on the overall performance. However, we do recommend the Essential Duvet Cover for an added layer of Outlast® temperature-regulation and breathability.

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.

The difference between the two comforter weights is the amount of filling. The Lightweight option is significantly lighter & thinner at about 1/4th'' thick, and is the best option for hot sleepers.

The All Season Comforter is more of a three season weight, and for those who prefer a bit more loft & thickness at about 2''. Both of the comforters are filled with Outlast technology to assist with keeping you cool with proactive heat management.
