Say goodbye to night sweats with these cooling (and stylish) PJs. Knee Length Shorts For Girls
If you’re a hot sleeper or are prone to night sweats, you know how uncomfortable it can be to wake up feeling like a hot, sticky mess. Cooling pajamas, made from breathable fabrics (like silk, bamboo, and linen) can help regulate your body temperature and wick away moisture to increase your comfort and sleep quality. Cooling pajamas come in a variety of cuts and types, too, whether you like to sleep in a tank top, night gown, or matching set.
To help you find sleepwear that will actually keep you cool all throughout the night, we put together a list of top picks in different materials, styles, and sizes. For further guidance, we consulted triple board-certified sleep neurologist Meredith Broderick, MD, of SoundSleepGuru for advice on how to shop for cooling pajamas.
The pajamas have a great size range and are made from breathable cotton.
They don’t prevent night sweats.
These pajamas meet all the criteria we look for in a standout cooling PJ set: They’re stylish, breathable, and available in a size range that includes sizes XS through 3X. Made from ultra-soft pima cotton, slipping on this sleep short and shirt duo envelopes you with cloud-like comfort as you drift to sleep. Cotton is a breathable material, so these PJs will help you stay cool at night by regulating your body temperature. However, if you’re a sweaty sleeper, cotton is not moisture wicking, so you may prefer a more drying fabric like bamboo viscose.
When it comes to style, these pajamas stand out for their contrast piping and functional chest pocket. It's available in 10 different colors, too. We also like that the boxer shorts have an elastic waistband for additional comfort and hit at the middle of the thigh, so they don’t feel too revealing. These pajamas are washable, so they’re easy to care for (though Cosabella recommends you hang them to dry). If you’re looking for a simple and airy set of pajamas for summer snoozes, this makes a great option.
Material: Cotton | Size Range: XS–3X | Care: Machine wash, hang dry
It has a fuss-free design that keeps you cool and dry all night long.
The V-neck cut may not suit everyone’s tastes.
There’s no denying that a nightgown is one of the most convenient sleepwear options, especially if you can never keep track of matching tops and bottoms. This pick features fabric made from bamboo, which is well known for its cooling properties. Bamboo is a breathable and moisture-wicking material, so it’s even great for preventing night sweats. Plus, it has a silky-smooth feel and stays cool to the touch, all while being budget friendly.
We love that this pajama set comes in an inclusive size range that ranges from XXS to 4X. As a bonus, it’s also available in a lot of different color options. In terms of style, this nightgown keeps things simple with a straight cut and a V-neck at both the front and the back. While some people may prefer a higher neckline, we love this option for hot sleepers on a budget.
Material: Bamboo viscose | Size Range: XXS–4X | Care: Machine wash, hang or tumble dry
These luxe pajamas are made with top-notch silk and can be machine washed.
They could have a better size range.
If you’re going to splurge on silk pajamas, this Eberjey set is the way to go. Made from 6A grade silk—the highest-quality silk you can get—it has a lustrous finish and glossy touch that makes bedtime a luxurious event. Plus, you don't have to sacrifice convenience for quality: The set is totally machine washable.
Silk is a thermoregulating material, so it keeps you cool in warm weather and cozy when it gets chilly—aka you can wear these year-round and always be comfortable. Plus, Eberjey uses 16 momme silk, which has a lighter density to allow for more breathability. However, it’s not moisture wicking, so it may not be the best choice if you tend to sweat a lot during the night.
From the cut of these pajamas to their perfectly relaxed fit, you can tell a lot of care was put into their craftsmanship, which makes them a worthy splurge. We wish they had a more inclusive size range, otherwise we think they're among the best pajamas around.
Material: Grade 6A 16 momme silk | Size Range: XS–XL | Care: Machine wash, lay flat to dry
The fabric is quick drying, which makes it a good choice to prevent night sweats.
It’s not ideal for those who prefer silk-like fabric.
If you’re into nightgowns, this pick from Cool Jams has a simple and stylish design that keeps night sweats at bay. Contrast piping around the neckline and front pleating add flattering details while keeping you dry with Cool Jams’ signature moisture-wicking fabric. It’s available in sizes S to XXXL and fun color options to boot.
Cool Jams uses a special polymicrofiber smart fabric in its pajamas, which has the soft and cozy feel your favorite cotton sleep dress has but with the added benefit of being quick drying and thermoregulating. These properties make it an excellent pick for those who deal with night sweats as it actually wicks away moisture instead of absorbing it like traditional cotton.
This nightgown is machine washable and can be tumble dried, though Cool Jams recommends hang drying to avoid static. Since it’s light material, it’s convenient to toss into a carry-on suitcase or duffel bag so you can sleep comfortably while traveling. The wrinkle-resistant fabric will be just as crisp when you take it out again at your final destination.
Material: Polymicrofiber | Size Range: S–XXXL | Care: Machine wash, hang or tumble dry
The cut of this tank is fitted around the shoulders, which prevents it from sliding off.
It's a little sheer.
This tank has an effortless quality that doubles as a casual top for running errands. Made from eucalyptus Tencel, a fabric made from pulverized eucalyptus trees, it offers amazing moisture-wicking and cooling abilities to prevent sticky night sweats from ruining your snooze. This tank is lightweight and breathable—a hero in the summer heat—and it’s hypoallergenic.
We’re fans of how this tank is constructed: While it has a looser cut that’s ideal for lounging, it’s fitted around the shoulders so you don’t have to deal with your top sliding around as you toss and turn. It can be machine washed and tumble dried for easy care, and since Tencel is so durable, you don’t have to worry about it ripping. That said, it does wrinkle quickly, so be sure to remove it from the dryer as soon as you can.
This tank is available in four different color options, but because the fabric is lightweight, the lighter hues may be a little see through. We don’t mind this much when it comes to pajamas, though. Overall, if you’re looking for a moisture-wicking and breathable sleep tank that doesn’t compromise on softness, this is a solid choice.
Material: Eucalyptus Tencel | Size Range: XS–XXL | Care: Machine wash, tumble dry
These casual boxers can be worn out of the house and have pockets.
There are limited color options available.
With their comfy elastic waistband and soft cotton fabric, you’ll look forward to slipping on these casual boxer shorts after a long day. The 3-inch inseams works well on taller and shorter, and the inclusive size range runs from XXS to 3X. If you're a fan of personalization, you can even add a monogram. However, we wish they came in more color options.
We think the best part about these boxers (other than their super-soft fabric) is the pockets, because who doesn't love pockets? Plus, the cotton fabric is substantial but still breathable, so they’ll keep you cool but aren't see through. Even though they're made with warm weather sleeping, their versatile design makes them well suited to act as a swimsuit cover up and to wear running a quick errand or on a sunny walk around the neighborhood. Since they’re well made and machine washable, all you need to do is pop these in the washer to have them clean for bedtime again.
Material: Cotton | Size Range: XXS–3X | Care: Machine wash
This stylish romper is made from washable silk and has a unique yolked waistband.
The inseam may be too short for some.
For those who prefer the convenience of one-piece sleepwear, this sleep jumpsuit by Cuyana is chic. It’s made from charmeuse silk, a fabric beloved for its lustrous sheen. This romper is remarkably soft to the touch and gentle on the skin with thermo-regulating properties to keep you from overheating at night. This jumpsuit is machine washable, making it a low-maintenance option to keep clean.
In addition to its high-quality fabric, this jumpsuit stands out for its comfy, elastic waistband and adjustable straps, which prevent it from sliding off your shoulders. We love the flattering yolk at the waistband, too. Our only qualms with this option are the less-inclusive size range (XS to XL) and the 2.25-inch inseam, which might be too short for taller folks. There's a 30-day return policy, though, which gives you plenty of time to try it on and send it back if you need to.
Material: Silk | Size Range: XS–XL | Care: Machine wash, hang dry
These lounge pants have a thick elastic waistband that prevents them from digging into your sides.
The wide-cut pant legs may be too long for shorter folks.
The whole point of loungewear is to be comfortable—why settle for pants that make you sweaty or overheated? This comfy pair of lounge pants are made from GOTS-certified organic cotton, which is processed without any irritating chemicals that can damage the environment (or your skin). They’re buttery soft and breathable for relaxing in warm and cool temperatures alike.
These pants are made with a thick elastic waistband and drawstring for the perfect fit without digging into your sides. While they have a good size range that runs between XS to 3X, we think they would benefit from tall and petite options since some may find the pant legs to run a little long, especially because they have a wider cut. When in doubt, be sure to check the size guide to make sure they’ll fit before ordering.
If you’d prefer a matching set, Pact offers a cropped lounge tee in the same silky and airy fabric as its lounge pants. Both garments come in a few color options to choose from so you can mix and match to your taste, and they’re both machine washable.
Material: Cotton | Size Range: XS–3X | Care: Machine wash
The lounge pants have a flattering tapered fit for wearing to sleep or out on the go.
The size range is a bit limited.
These breathable sweatpants will help you stay cool, calm, and collected in transit, even if you have to sprint through the airport. The luxuriously soft pima cotton is incredibly cozy for sleeping in your bed or on a plane, and it's breathable, so you won't overheat no matter what the climate is like when you step out of the aircraft.
As far as style goes, these lounge pants have a slim fit and tapered leg—this gives them a neater look compared to traditional baggy sweatpants. They also have a drawstring waistband, so you can adjust their fit as needed throughout the day to stay comfortable, though we still recommend you check their size guide first before ordering to ensure a proper fit.
Outside of travel, these comfy cotton pants are a top-notch pick for your sleepwear needs. They’re machine washable, they won’t make you sweaty, and the cozy cotton fabric gets softer the more you use them—what else could you want in a pair of PJ pants?
Material: Cotton | Size Range: XS–XL | Care: Machine wash, dry on low
These size-inclusive pajamas are made with moisture-wicking bamboo viscose to keep night sweats at bay.
They aren’t ideal for people who prefer fitted sleepwear.
This pajama set is made from bamboo viscose that’s as soft as can be, and it’s available in an inclusive size range that runs from small to 4X. Its relaxed fit feels weightless to wear, and the bamboo material works wonders at wicking sweat and keeping your body temperature regulated. It comes in a range of color options, including both neutral and vibrant hues.
Because bamboo viscose is a durable material, you don’t have to worry about these pajamas pilling, even after a few cycles in the washing machine. The set stays cool to the touch during hot weather, so you’ll never wake up feeling hot or clammy, and it’s hypoallergenic, which is ideal for those with skin sensitivities.
The pajama pants have an elastic waist to stretch as needed, and while they aren’t ideal for those who prefer a fitted look, the loose fit promotes airflow. The trimmed V-neck and matching cuffs add some subtle style to your sleepwear, too.
Material: Bamboo viscose | Size Range: S–4X | Care: Machine wash
This pajama set is made with a relaxed bamboo viscose knit.
The pants may be too big on shorter people.
Cozy Earth’s bamboo PJ set stands out for its stylish details and flattering fit. It’s made from a bamboo viscose stretch knit, which offers a smooth touch and drapy fit that promotes air flow and prevents irritating bunching. The material feels ridiculously soft against the skin, and the contrast piping adds a luxe touch.
In addition to being stylish, these pajamas are also functional. The pants come with pockets, perfect for storing tissues, hair ties, or other bedtime essentials, and the drawstring waist ensures they won’t be too tight or loose. However, they have an oversized fit, which petite people may find too baggy.
These pajamas come in a nice array of color options and can be machine washed and dried—no hang drying needed here. Just be mindful that bamboo viscose can wrinkle easily, so be sure to remove it promptly from the dryer to prevent creasing.
Material: Bamboo viscose | Size Range: XS–XXXL | Care: Machine wash, tumble dry
Made from ultra-soft pima cotton, these pajamas come in elegant patterns.
They shrink slightly in the wash.
Cotton is often recommended for cooling pajamas for a reason: It’s lightweight without being flimsy and offers exceptional breathability. However, some cotton varieties are better than others. This pajama set from Lake uses high-quality pima cotton that’s durable and silky-smooth due to longer fabric fibers. Pima cotton doesn’t pill as easily as short-staple cotton, and it feels buttery soft against the skin. However, it does shrink slightly when you first wash it.
The material of this pajama set isn’t the only thing that sets it apart. Both the pajama shirt and shorts are well crafted to ensure a relaxed fit without being too baggy. Thoughtful details like a scoop neck and contrast piping throughout add extra style so you can feel comfy and cute while heading to bed. We’re also a fan of the elegant pattern options this PJ set comes in, so you don’t have to settle for neutral pajamas.
Material: Pima cotton | Size Range: XXS–XXL | Care: Machine wash, lay flat to dry
These pajamas are made from washable silk and feature luxe tulip details.
You can’t mix and match sizes.
Elegant, well made, and easy to care for, this PJ set from Lunya has everything we look for in a good pair of silk pajamas. Lunya uses temperature-regulating mulberry silk for a flattering drape and subtle sheen. It's machine washable, so you don’t have to go out of your way to keep your stylish sleepwear clean.
Both the PJ top and shorts have tulip detailing, which add an elegant touch and extra airflow for additional cooling. The tank has a racerback cut, so you don’t have to worry about the straps falling off as you sleep. We appreciate that the set comes in darker and lighter hues to match your color preferences, too.
The one area we think these PJs could be improved is in their fit flexibility. While the shorts have a soft elastic waistband, they don’t have a drawstring, so they can’t be adjusted, and you can’t mix and match the top and bottom sizes. Still, for the high-quality fabric and washable convenience these pajamas offer, we think they’re a good pick for those looking for a chic silk set.
Material: Mulberry silk | Size Range: XS–XL | Care: Machine wash, lay flat to dry
These linen pajamas come pre-washed for extra softness.
They’re not budget friendly.
If you want to stay cool during hot nights, this linen pajama set from Serena & Lily has you covered. Linen is one of the best fabrics for hot sleepers because it’s breathable and wicks away moisture. Plus, it’s temperature regulating, so you'll stay cozy in the winter months, as well.
Serena & Lily use Oeko-Tex-certified linen, which means it’s processed without chemicals that can cause irritation or unpleasant odors . The brand also pre-washes its fabric to ensure your pajamas arrive buttery soft. Due to the nature of linen, they’ll continue to get softer and cuddlier as you wash them. These durable pajamas can be machine washed and tumble dried—just keep in mind that linen wrinkles easily.
Even though linen has a relaxed look, these pajamas still exude luxury, thanks to their craftsmanship. Stylish details like mother-of-pearl buttons, piping, and finished edges help justify the splurge. They’re also quite comfortable due to their baggy fit and adjustable waistband, but you can always size down for a more tailored look if you need to.
Material: Linen | Size Range: XS–L | Care: Machine wash, tumble dry
We choose the Cosabella Bella Short Sleeve Top & Boxer Pajama Set as our best cooling pajama pick because of its size inclusivity and soft, breathable cotton fabric. For a budget pick, we like the WiWi Bamboo Nightgown because it has a simple design and is made from moisture-wicking bamboo fabric.
Cooling pajamas come in all the same styles that regular pajamas do—nightgowns, boxer shorts, button-down sets, you name it. According to Dr. Broderick, there’s no one best style: “It depends a little bit on other factors like the climate where the patient resides. For instance, is it hot there or cold and is there air conditioning? Is it humid? Other factors like what kind of bedding is being used and if the person has any special circumstances like night sweats that might play a role in choosing the best pajamas."
Make sure to take a look at your current sleepwear preferences. While some people may prefer the airy feeling that a silky sleep set like the Lunya Washable Silk Tulip Back Set provides, others will feel more comfortable in a cozier cotton fabric like the Petite Plume Women's Pima Lounge Pants, especially if you live in a climate that gets cold weather.
Dr. Broderick’s advice is to look for fabrics that are durable and practical when shopping for cooling pajamas, and there are a lot of lasting materials out there that may be better suited for your needs than others. Here’s a quick breakdown of the most common fabric types you’ll find in cooling pajamas:
Silk: Silk is made from the fibers spun by silkworms. It’s renowned for its thermoregulating properties and shiny, luxe appearance. Silk is a breathable material, but it can stain if you get sweaty. High-quality silk is often pricey and typically requires hand washing or dry cleaning, but the good news is that there are plenty of washable silk PJ options there, like the Eberjey Inez Washable Silk Short PJ Set, the Cuyana Washable Charmeuse Sleep Jumpsuit, and the Lunya Washable Silk Tulip Back Set.
Bamboo viscose: This fabric is made by pulverizing and processing bamboo plants, which are spun into long fibers that yield a smooth, silky, and sturdy material. Bamboo viscose effectively wicks away moisture and provides good airflow, making it an ideal choice for those who live in warm climates or get night sweats. It’s hypoallergenic, too, so it helps prevent skin irritation.
Eucalyptus lyocell: Eucalyptus lyocell—sold under the brand name Tencel—is made from crushed eucalyptus tree pulp and shares the same moisture-wicking and temperature-regulating abilities as bamboo viscose. Some people find that bamboo has a softer touch while eucalyptus is more crisp. Overall, these two materials are very similar, and you can’t go wrong with either when it comes to cooling sleepwear.
Linen: Linen is a natural fiber made from the flax plant that excels in moisture wicking and temperature regulation, which prevents your PJs from trapping your body heat. It also has a more relaxed fit and rougher feel than silk. As you wear and wash your linen pajamas, the fabric fibers will break down and become softer over time.
Cotton: Cotton is a very breathable material with temperature-regulating abilities that can help you sleep comfortably in warmer weather. On the other hand, it absorbs moisture as opposed to wicking it, so it’s not ideal for preventing night sweats. When shopping for cotton pajamas, look for options made from long-staple cotton varieties like the Lake Pajamas Pima Shorts Set, which are smoother and more durable than short-staple cotton.
Most cooling pajamas can be tossed in the washing machine, though some options made from more delicate materials like silk may need to be hand washed or dry cleaned. It’s a good idea to check the manufacturer’s instructions before purchasing pajamas to make sure you’ll be able to care for them properly.
While you can’t go wrong with silk, bamboo, linen, or cotton, linen is more breathable and moisture wicking than the rest. It will likely help you stay the coolest.
Silk pajamas have cooling effects due to their smooth fabric and breathability. Silk is also a temperature-regulating material with insulating properties, so it can also help keep you warm during colder weather.
If cooling pajamas aren’t enough for you, you can upgrade the rest of your bed with cooling sheets, blankets, pillows, and comforters to regulate your body temperature and prevent night sweats. Like these PJ picks, many cooling bedspread options are made from fabrics like cotton, bamboo viscose, and linen.
