The Best Cooling Pajamas, Tested by Hot Sleepers

✔️ WHAT TO KNOW: Eberjey's Gisele set is widely popular and understandably so. It comes in classic silhouettes, from long pants to short sets and nightshirts with piped details for a chic look. The modal fabric is a tester favorite for its lightweight feel and soft drape.

✔️ LAB RESULTS: This set excelled in our laundering tests, and I've personally worn mine for close to four years. While the fabric can wick away moisture in a pinch and has a general cool-to-the-touch feel, modal generally doesn't stand out when it comes to temperature regulation. Still, the thinner fabric helps with breathability.

✔️ TESTER FEEDBACK: Testers particularly loved that the set felt lightweight and thin yet not flimsy, especially compared to similar styles. As a result, several testers have opted to wear it year-round, both during hot summer months and chilly winters. One noted, "I didn't overheat like I do with other pajamas."

✔️ WHAT TO KNOW: These classic pajamas are a comfy upgrade of a tailored button-up shirt. They're made from crisp, airy cotton fabric and have a relaxed fit for extra comfort and breathability. As a best-seller from J.Crew, the set comes in a few classic colors, plus rotating prints and patterns like the seasonal pinstriped option pictured here.

✔️ LAB RESULTS: Cotton isn't known for its moisture-wicking properties, and these are no exception. Still, we noticed that the fabric was lighter than other cotton sets without feeling flimsy. The boxy silhouette also helps promote airflow throughout, especially compared to fitted styles.

✔️ TESTER FEEDBACK: I've owned this set for a little over two years, as has GH Textiles Lab Associate Director Emma Seymour, and love how relaxed the fit is without feeling too large on my frame. The main call-outs from testers are that the fabric feels crisp and airy, though it tends to wrinkle more than popular knit styles. Still, testers (and I) love the overall look.

✔️ WHAT TO KNOW: If you want a menswear-style pinstriped set that still keeps you cool, try these woven pajamas that are lightweight yet retain the structured design of cotton poplin PJs.

✔️ LAB RESULTS: The rayon-lyocell fabric wicked away moisture better than 100% cotton but not as well as other synthetic picks. Still, the fabric washed well, without any major changes in appearance, according to our testers. This set also had a nice weight: It felt more substantial than an all-cotton set but not as hefty as drapey rayon knit pajamas.

✔️ TESTER FEEDBACK: I liked how the fabric didn't cling to my body, which is common for most Tencel lyocell styles nowadays due to their knit structure. Testers unanimously gave these pajamas perfect scores for comfort. "I’m a hot sleeper, and they don’t cause me to overheat or break out in sweat at night," shared one, although another tester didn't observe a major change in their body temperature while sleeping in these.

Note that Cozy Earth claims to offer products made with "bamboo," but we've found that most bamboo fabrics are actually rayon with no trace of bamboo in the final material.

✔️ WHAT TO KNOW: Soma's Cool Nights Collection is one of the most well-known lines in the cooling pajama market and comes in dozens of classic and trendy silhouettes. While styles come in and go, you can't go wrong with this simple and versatile tee, which pairs well with any of the matching bottoms including shorts, long pants, or cropped pants.

✔️ LAB RESULTS: Several sets earned perfect scores from users on overall comfort but received average scores for moisture-wicking during Lab tests. So if your night sweats are intense, these may not be the perfect option.

✔️ TESTER FEEDBACK: The drapey rayon fabric was a hit among our testers for its soft feel and lightweight nature. One tester who tried a different style than the one pictured said, "I was skeptical about sleeping in long sleeves and pants because I am such a warm sleeper, but I was in disbelief that these kept me from sweating!"

I've tried several different silhouettes from this collection, and you can't go wrong with any of them. If you want something soft and drapey that won't weigh you down, these Soma pajamas deliver.

✔️ WHAT TO KNOW: When it comes to cooling comfort, Cool-jams surprised our testers and analysts alike with its performance. While this set isn't the most trend-forward option in our guide, we like that the brand offers variations with long-sleeve options, shorts, and more.

✔️ LAB RESULTS: The set didn't shrink during our laundering tests, though it did pill when we assessed durability.

✔️ TESTER FEEDBACK: While our testers were skeptical that a short-sleeve top and pant set could prove cool and comfortable, Cool-jams ultimately earned full marks for comfort. They said the microfiber fabric was super soft and felt lightweight on their skin.

One textiles analyst reported that her set fit better than other pajamas she's tried and "didn't shift during the night." Another tester remarked, "[These pajamas were] so comfortable, and as someone who generally overheats at night, these were great."
