Why choose a comforter?
A comforter is different from a duvet.
A duvet is a plain insert filled with down or synthetic fibers and used inside a duvet cover. This means that people can change the duvet and duvet covers when they want to, such as according to the season. There are varying duvet thicknesses to suit the changing temperatures throughout the year.
A comforter, on the other hand, is made out of more durable fabric than a duvet, as it is not used inside a cover. Comforters contain down or synthetic fibers. They offer an advantage over duvets in that they do not move around inside a duvet cover since a cover is not necessary.
However, comforters can be harder to wash and will likely become less soft over time.
What to look for
Here are some features to look for when choosing a comforter for hot sleepers.
Outlast is a brand of phase change material (PCM) that experts originally developed for NASA. It absorbs, stores, and releases heat to regulate temperature. It is common in fabrics that continually regulate a person’s temperature.
Outlast
Outlast technology does not wick moisture away from the skin as a person sweats. Instead, it works to prevent sweating by controlling a person’s temperature before they become too hot and begin to sweat.

Choosing a comforter made from sustainable fabrics or made through responsible production methods means that it will have little negative impact on the environment.
Tencel fabric is one sustainable fabric option that manufacturers often use in comforters.
A range of certifications indicates that a company sustainably makes products with safe materials.
These certifications include OEKO-TEX, which ensures that companies make products without harmful substances or unethical work practices or conditions and that the manufacturers have produced them in an environmentally sustainable way.
