Momcozy CoolMurm BK003 Cooling Comforter (Twin/Twin XL): fabric and care

The Momcozy CoolMurm BK003 is a lightweight comforter designed for people who sleep hot. It is sold in a Twin/Twin XL size of 68 x 90 inches and weighs 5.7 lb (about 2.6 kg). Momcozy aims it at hot sleepers, including those who feel warm in pregnancy, and uses fabrics that feel cool to the touch.

How the cooling fabric works

Momcozy says the cover combines cool-feeling nylon yarn with mica cooling particles, an approach it likens to a mint-gel sensation on the skin. The brand says the surface feels cool on contact and that it can lower perceived skin temperature by 6°C (about 11°F). That is the brand's figure, and a cool-to-touch feeling is not the same as a measured change in body temperature.

Nylon moves heat away from the skin quickly and absorbs little moisture, which is why it is often used in cooling fabrics. Momcozy says the mica particles are physical, not a chemical coating, and are wrapped inside the fibre, so the cooling effect shouldn't fade with washing. It adds that when one side feels less cool after hours, you can turn the comforter over for additional cool time.

The lyocell filling

The filling is regenerated lyocell fibre, a cellulose fibre made from wood pulp. Momcozy says it resists odours, is soft and is OEKO-TEX certified, and that it is suitable for sensitive skin. Lyocell typically wicks moisture well and dries quickly, and the brand says the tight knit and breathable weave help airflow and keep temperature steady through the night.

Durability and washing

Momcozy says the comforter is tested for 50 or more washes, with triple-reinforced stitching and stretchy, snag-resistant fibres, and that this suits homes with pets. Always follow the care label for washing temperature and drying.

Size and fit

Twin/Twin XL beds are narrow, so the 68 x 90 inch size suits a single bed. On a double or larger bed, it would only cover one person. Its colour is beige yellow, according to the listing title.

Who it suits

It suits people who wake up warm, those who sleep in a room with air conditioning and want a light cover, and anyone who wants a comforter that feels cool to the touch in warm weather. In winter, a hot sleeper might still add layers.

What to check before you buy

• Room temperature: cooling fabrics work together with the room; check what you need.
