Top 6 Best Cooling Pajamas in 2025

Sweaty nights? Yeah, we’ve all been there. If you’re constantly kicking off the covers, flipping your pillow, or waking up in a hot mess, it’s not just in your head. Overheating at night is more common than you think and can seriously mess with your sleep.

The good news? You don’t have to suffer through it. Cooling pajamas are designed to help regulate your body temperature so you stay dry and comfortable and get some good sleep.

In this post, I’ve rounded up the best cooling pajamas, based on fabric, comfort, real user reviews, and how they hold up in real sleep. Let’s get started.

6 Best Cooling Pajamas

1. Evercool® Cooling Pajama Pants Set

The Evercool® Cooling Pajama Pants Set is made with Rest’s signature Evercool fabric, known for its ultra-soft feel and temperature-regulating properties. The fabric pulls heat away from the skin while remaining breathable and stretchy, making it ideal for hot sleepers. The set includes a relaxed-fit tee and jogger-style pants with a wide waistband that stays put without digging in.

It can be cleaned in the machine, and despite numerous washings, it will not lose its cooling impact, which is not always the case with tech fabrics. The moisture-wicking also implies that you are less likely to wake up sticky. It is a good choice if you like full-length coverage but want to keep it comfortable.

Pros

• Soft, lightweight, and breathable

• Maintains cooling performance after washing

• Wide waistband for a comfortable fit

Cons

• Limited color options

• May feel too lightweight for cooler seasons

2. Evercool® Cooling Pajama Shorts Set 

This short version of the Evercool set offers the same cooling benefits but with a breezier silhouette. It’s perfect for warmer nights or anyone who prefers to keep their legs uncovered. Like the pants version, the shorts are made from the brand’s signature fabric that helps regulate your body temperature and wick away sweat throughout the night.

The tops are generous and very slightly flowy rather than piled on, and the shorts have a gentle elastic waistband and a bit of stretch. It is a lazy, low-maintenance alternative that looks polished, regardless of whether you are slouching on your day off.

Pros

• Ideal for hot climates or night sweats

• Comfortable, stretchy waistband

• The cooling effect feels immediate on the skin

Cons

• Runs slightly big for petite frames

• Less suitable if you prefer more coverage

3. Dagsmejan Nattcool Air Sleep Tech Slip Dress

The Dagsmejan Nattcool Slip Dress combines smart fabric tech with soft, breathable comfort. The fabric is composed of a blend of beechwood fibers and performance materials, so it can help regulate the body temperature while remaining lightweight and airy. It is chilly to the touch and has a good heat and moisture dissipation rate, so it is appropriate when the sleeper is hot or restless.

The slip-style cut allows for many movements and allows normal air circulation throughout the night. It is also resistant to odour and dries quickly, which is good for people who sweat a lot. It is quite expensive, but the quality and clever design make it a standout.

Pros

• Feels cool immediately on contact

• Odor-resistant and moisture-wicking

• Eco-friendly and sustainably made

Cons

• Higher price point

• Thin straps may not suit all preferences

4. Lake Alice Nightgown

The Lake Alice Nightgown keeps things classic in the best way. It’s made from 100% cotton poplin, which feels light, crisp, and breathable, perfect if your skin gets fussy with synthetic fabrics. The fit is relaxed with short sleeves and a modest neckline, and it manages to hold its shape without feeling stiff or uncomfortable.

Now, it’s not one of those high-tech moisture-wicking fabrics, but that’s kind of the charm. It is cool, easy, and uncomplicated, which makes it perfect to wear by a hot sleeper who likes to feel something natural and relaxed. It is adorable enough to wear when you have to get a cup of coffee or take a short walk outside.

Pros

• 100% breathable cotton

• Flattering, classic fit

• Gentle on skin

Cons

• Doesn’t wick sweat like technical fabrics

• Needs ironing to keep it crisp

5. Lunya Washable Silk Tulip Dress

The Lunya Washable Silk Tulip Dress is a breathable and weightless nightdress. Its extended side slits allow you free movement and the capability to stretch yourself when sleeping. The racerback design on the back leaves your arms and shoulders free.

This dress, made of 100% mulberry silk, is both luxurious and convenient. It can be completely machine washed, which is easier than with other silk dresses. If you like a smooth finish, wrinkles can be removed easily by light steaming after washing.

Pros

• Machine-washable silk

• Beautiful and breathable design

• Adjustable straps for a custom fit

Cons

• Pricey compared to other options

• May wrinkle more easily than synthetics

6. Cozy Earth Stretch-Knit Pajama Set

Cozy Earth’s Stretch-Knit Pajama Set is made from bamboo-derived viscose, known for its buttery softness and cooling abilities. The fabric naturally wicks away moisture, keeps you dry, and has a silky feel that’s gentle on sensitive skin. Plus, the softness of these pajamas gives a lightweight, comfortable feel suitable for all-day wear.

The range consists of a button-down long-sleeved shirt and a pair of loose-fitting trousers, ideal for cool nights or in air-conditioned environments. It also resists pilling and stretching out, and can handle washings very well, which is a major advantage with respect to long-term comfort.

Pros

• Ultra-soft bamboo viscose

• Great for sensitive skin and hot sleepers

• Retains quality after washing

Cons

• Not ideal for very hot nights

• On the pricier side

Key Features to Choose Cooling Pajamas, According to a Sleep Expert

Cooling pajamas can help you sleep tremendously, particularly if you experience night sweats, hot flashes or are simply a hot sleeper. These features, as outlined by sleep experts and reviewed below, are among the best in keeping you cool and comfortable when looking to purchase sleepwear.

1. Cooling, Breathable Fabrics

This is the most important thing to look for. Materials like bamboo viscose, cotton, TENCEL™, and certain performance blends are naturally breathable and allow heat to escape. Avoid heavy synthetics like polyester that trap heat. The goal is to help your body cool down naturally throughout the night.

Rest’s Evercool® fabric is a great example of this in action. It’s engineered to feel cool to the touch and stay that way throughout the night. Lightweight and breathable, it helps regulate your body temperature while also wicking away sweat. If you tend to overheat, this fabric works with your body, not against it.

2. Moisture-Wicking Technology

It’s not just about staying cool—it’s also about staying dry. Fabrics that wick moisture away from your skin help prevent that sticky, uncomfortable feeling from sweating at night. Moisture-wicking pajamas draw sweat to the surface so it can evaporate faster, keeping you feeling fresher.

3. Lightweight Material

You want something that feels light and airy on your skin, because heavy, thick materials can make you feel weighed down and even hotter, especially when you’re already under blankets or layered with sheets.

That’s why pairing lightweight pajamas with breathable, cooling sheets can make a real difference. Lighter fabrics not only feel more comfortable but also allow better airflow, which is key for regulating your body temperature through the night.

4. Loose, Non-Restrictive Fit

Clothing that is too tight may entrap heat and poorly circulate air near your body. Choose a loose or airy style of pajamas, such as loose-fitting bottoms, baggy shorts, or A-line night dresses. Mobility and comfort allow your body to move more easily and provide it with the ability to cool down during the night.

5. Skinny Seams and Intelligent Design

The construction of a pajama set is more important than you imagine. The fewer the seams, the fewer the places where heat can accumulate and where the fabric can press up against your skin. Extra credit items such as flat seams, easily fastened waistbands, or uncluttered adjustable straps that add to comfort but not bulk.

6. Thermoregulating Properties

Certain materials (such as silk, bamboo, or performance blends) have the ability to adjust to the temperatures of your body. This means they can help to keep you at the desired level by cooling you down when you become too hot and warming you up a bit when you are cooler. This is fantastic if your body temperature tends to waver during the night.

7. Fast Dried and Non-Stinking

Sweating at night is normal, and your pyjamas ought not to be wet or smell. Rapidly drying fabrics resprung rapidly following the absorption of moisture, and you will also wake up fresh even when your night was a sweaty one (odor-resistant fabrics).

8. Washable and Maintainable

You are going to be wearing these knickers every night (and sweating in them), so you would prefer a material that can withstand regular washing without disintegration. Consider fabrics that can be washed in the machine, do not lose their form, and remain soft after a few rounds of washing.

Final Thoughts

Sleeping hot doesn’t have to be your norm, especially with cooling pajamas designed to help your body breathe, stay dry, and actually rest. Whether you prefer soft bamboo sets, silky slip dresses, or moisture-wicking tech fabric, there’s something on this list to fit your style and your sleep needs.

At the end of the day, comfort matters. Investing in the right sleepwear might seem small, but when it helps you sleep better and wake up feeling fresh—not sweaty—it’s totally worth it.

Sweet dreams and cooler nights ahead!
