As much as I'd like to tell you my nights are as chill as Sleeping Beauty's peaceful (if cursed) sleep, in reality, they're more like that old couple in Titanic. You know, the one that lays down together to face the cold embrace of the ocean? Replace the ocean with overwhelming heat and night sweats, and you've got a pretty good picture of what my REM cycle looks like. There are many ways to combat those hot, sweaty nights—you can make your bed with cooling sheets and a cooling blanket or aim a cooling fan right at yourself for a steady breeze while you sleep. But nothing will do a better job of keeping you from burning up at night than cooling pajamas.

From personal experience, a general rule of thumb when it comes to cooling pajamas is that no matter the fabric, the less on your body, the cooler you will be. That said, not everyone is comfortable sleeping nude, or in a tank top, or in a nightgown, etc. So as someone who prioritizes comfort above all else, I've rounded up the best lightweight pajamas of all different styles to suit whatever sleepwear preferences you may have because everyone deserves to have a sweat-free night.

Read on to see shop all our picks for hot summer nights and beyond. May your sleeps be dry from here on out!

Cloud Sleep Dress

I can't stop buying this Cloud Sleep Dress from Parade. Part of their Supersoft collection, it's made of 95% Tencel, so it's super lightweight and thin, aka great for those sweaty nights.

MY REVIEW: "I truly love this nightgown, which I could definitely also wear as a dress if I had the right undergarments. It's comfortable and sexy, and though it's not moisture wicking, it's so thin, it doesn't really matter."

Soft & Breathable V-Neck Pajama Set

This affordable pajama set is made of a lightweight rayon blend designed to be moisture-wicking and keep you cool at night. It comes in a bunch of different colors and can be mixed and matched with any other sleepwear.

THE REVIEW: "Great PJs! They are so soft and comfortable," writes one tester. "They are lightweight and breathable, but the fabric is still pretty durable and not see through."

Sleeveless Racerback Nightgown

This midi-length racerback nightgown is made with bamboo viscose, known for its soft, breathable properties. It can also double as a dress in a pinch, which makes it a hot girl summer must.

THE REVIEW: "I love these nightgowns. They are so soft and keep you cool at night too," one reviewer writes. "Now when I get hot I can sleep with comfort and not have to rip off my night clothes to get cooled off."

Rib Xssentials Romper

Full disclosure: this rib knit romper isn't advertised as being specifically cooling, but thanks to its relaxed fit and, ahem, minimal fabric, it's a nice sexy option for hotties looking for some relief.

THE REVIEW: "The romper is so comfortable and the material feels so soft," a tester writes. "It fits true to size and very flattering."

Short Sleepwear Set

Not only is this pajama set 100% flax linen—a super lightweight fabric that dries faster than you sweat—it also comes in over a dozen cute colors. The shorts and short-sleeved button down combo looks so sophisticated, it could totally double as a summer look.

THE REVIEW: "I absolutely love this set. I can use the pieces as separates and actually wear them out during the day as they're cool and comfy," writes one tester. "It definitely plan on getting another color!"

SleepWell with TempTech Pajama Sleep Pant

These HUE pajama pants feature the brand's TempTech, which is supposed to help regulate your body's temperature, cooling you down when you're hot and warming you up when you're cold. They're also made from moisture-wicking fabric to keep you fresh, even if you do still get the occasion night sweat.

THE REVIEW: "They really do keep you cool on hot nights and warm on cold ones," one reviewer notes. "There can be a 20 degree difference from one night to the next! These pants don't care. They keep me comfortable all the time."

Nattcool Sleep Tech Shorts

Made with eucalyptus fibers, these sleep shorts from Dagsmejan don't hold onto moisture. In other words, any sweat will be dried—fast—so you won't have to worry about waking up with a sudden sticky feeling.

THE REVIEW: "The fabric is very soft and comfortable," one reviewer notes. "I have not had a night where I wake up feeling overheated."

Rib-Knit Bamboo V-Neck Tank Lounge Dress

Cozy Earth's rib-knit dress is made of 97% viscose from bamboo, so it's light and breathable. The nightgown has a loose cut, but isn't too triangular that it loses all shape.

THE REVIEW: "This gown feels just lovely and sumptuous on. It has a nice weight to it, but is breathable," writes one tester. "As a person who suffers from hot flashes, I have found this to be the least restrictive material."

In Your Dreams 2-Piece Set

The last thing you want to do when it's really hot out is put on layers of constricting, body-hugging lace lingerie. This two-piece satin pajama set from YITTY gives you the glam and flirty vibes of lingerie while also being loose enough for you to breathe.

THE REVIEW: "I am in love," one reviewer writes. "I love to put the set on after a nice relaxing bath. It's the perfect way to pamper yourself every evening."

Kaitlyn Wide Leg Sleep Jumpsuit

This wide-leg jumpsuit is made of 100% cotton, which provides lightweight coverage—perfect for those who tend to sleep hot.

THE REVIEW: "This fit perfectly," one reviewer writes. "I would def buy more colors."
