10 Best Cooling Comforters for Hot Sleepers 2024

For the fluff of down without the warmth of it, Saatva made a down alternative out of a fluffy lyocell fill. This sits inside of a cotton shell, designed with a 200-thread count. As the brand notes, higher thread counts often feel silkier, but they also trap heat. A lower thread count means there’s more room for the fabric and your body to breathe.

Eucalyptus has been a favorite material innovation lately for its lightweight, sweat-wicking properties. It has a cool, silky feeling, which is a pleasure to sleep in but also makes it susceptible to slipping off the bed if you tend to move around. To make sure the comforter stays as cool and hygienic as possible around sweaty sleepers, Sijo added a silver ion anti-microbial treatment—often used in workout clothes—to kill the bacteria that make something like a comforter start to stink.

Pottery Barn also makes use out of that cooling TENCEL lyocell, but in its own way. The front is made up of that sweat-wicking lyocell but the back is a silky cotton sateen. You really get the best of both cooling worlds, particularly useful to those sleeping one leg in and one leg out.

If you have a cozy flannel or similar for your winter bedding, swapping it in for a linen duvet cover is the way to go. This flax linen duvet cover has a super airy weave, leaving plenty of room for that AC to get in and your sweat to air out.

If you live in a warm, humid climate—or if you tend to make any climate you’re in warm and humid—Casper designed a duvet to keep you cool in it. It’s made with a light down filling, which have thin sewed chambers to keep the down from bunching up, inside of a cotton and wool shell. Merino wool is known for its natural sweat-wicking properties, a particular favorite material for socks. Choose from a lightweight or heavyweight one, both with that wool layer.
