Best Cooling Pajamas for 2025, Tested by Hot Sleepers

I recommend Cozy Earth to everyone in my life, especially the bamboo pajama set. The stretch-knit bamboo material is buttery soft and feels rich and creamy against the skin. It never makes me feel overly warm, as bamboo is naturally breathable, temperature-regulating and moisture-wicking. 

This set is available in short and long sleeves and 15 different colors. I love how it fits -- each piece is flowy, stretchy and non-restricting. The buttons, pockets, piping and collar design resemble a pajama set you would expect from a high-end hotel and spa. Everything about these Cozy Earth pajamas screams comfort and luxury.

Material: 95% Bamboo viscose, 5% spandex

Pros

• Softest silky feel 
• Size inclusive (XS-3XL)
• Drawstring and pockets
• Available in 15 colors and patterns

Cons

• More expensive than traditional cotton pajamas

Before my boyfriend tested some cooling pajamas for this roundup, he was a bit skeptical, but he is now a true Cozy Earth fan. Thanks to its simple, stylish design, this bamboo stretch-knit pajama shirt can easily transition into loungewear. My boyfriend says it has the softness and comfort of his favorite old tee. 

You can tell (and feel) that Cozy Earth’s bamboo pajamas are made with premium materials. Bamboo helps you sleep cooler thanks to its adsorbent, quick-drying qualities. My boyfriend loves how well it fits his frame and isn’t too tight around the shoulders. The loose, flowy fit helped him to stay temperature-neutral and comfortable all night. 

Each piece is sold separately. The matching shorts cost $90.

Material: 95% Bamboo viscose, 5% spandex

Pros

• True to size
• Luxurious feel
• Pockets

Cons

• More expensive than traditional cotton pajamas

The lightest pajamas I tested also won the best silk pair. Lilysilk takes the crown for its unmatched luxury, soft and smooth touch and beautiful design. Its cooling abilities, combined with the lightweight and airy fabric, make this set perfect for hot sleepers.

Silk is one of the most expensive cooling pajama materials, yet, compared to other high-end silk brands I researched, this set isn’t as expensive as silk can get. Yes, it is more expensive than traditional cotton pajamas, but Lilysilk’s feel and lush details, such as its pockets, pipping, and draping, can be justified. The set comes in four colors, and the care instructions are hand wash cold, line dry, cool iron, or dry clean.

Material: 100% Mulberry silk

Pros

• Truly luxurious look and feel
• Machine washable silk
• Under $200 for a set

Cons

• They wrinkle easily
• The V-neck plunges low; would love one more button
  

Quince is known for its affordability, even when it comes to silk. Quince’s washable pajamas are 100% Mulberry silk, making them very lightweight. I've tried other Mulberry silk pajamas, but these feel a little different. The outer shell of the tee feels similar to lightweight suede material that's matte, soft and drapey. Be aware that this set will not look or feel exactly the same as the Lilysilk pajamas above.  

There isn't any stretch, as you'd expect from silk, but they are nice and flowy. I found they helped me feel dry and temperature-neutral during the night. If you're larger in the chest area or between sizes, I would size up since there is little give with the material. Quince’s washable silk pajamas are also available in men’s sizes.   

Material: 100% Mulberry silk

Pros

• Machine washable silk 
• Affordable, lightweight and comfortable

Cons

• Not as soft as other silk or bamboo options on this list
• Feels similar to artificial silk or suede
• Chesty, broad-shouldered individuals should size up

I like to wear oversized T-shirts to bed, and this chemise or nightdress from Lilysilk recreates that feeling in a much more luxurious, feminine way. The smooth 100% Mulberry silk feels light and gentle against the skin, and it doesn't cling in weird areas. It fits similarly to other slip dresses that I have in my closet. 

The spaghetti straps are adjustable, and they aren’t so delicate that they fall off my shoulders. While it doesn’t have the same pockets or pipping details as the brand’s silk set, it still has a light, smooth and cooling feel. It is also available in three more vibrant, beautiful colors. The brand recommends hand washing cold, line drying, cool ironing or dry cleaning.

Material: 100% Mulberry silk

Pros

• Beautiful vibrant colors
• Light and soft on the skin 
• Adjustable straps
• Could be worn as a normal dress

Cons

• Wrinkles easily 
• On the shorter side

If you're searching for the best and softest sleep shorts for night sweats, Luxome has you covered. They are made of modal, a light and dreamy fabric that is softer than cotton and similar to bamboo or silk.  The material wicks moisture away from the body while you sleep. The pajamas look and feel similar to Cozy Earth but are a bit heavier. Not to mention that the design is chic with draping, side pockets and side seam slits at the leg openings. My favorite is the stretchy waistband that lets you move comfortably through the night.

I didn't experience any severe night sweats with the Luxome modal sleep shorts. I didn't notice any active cooling while wearing the pajamas, but it's great for keeping sweat and moisture at bay. To care for these pajamas you should machine wash on cold and tumble dry with delicate, low heat. 

Material:  95% Modal, 5% spandex

Pros

• Extremely stretchy, soft and smooth  
• Chic design and available colors
• Wide elastic waistband, pockets and drawstring 

Cons

• Not everyone may like the high waistband
• I lost the drawstring after a few washes
  

The Tasc bamboo silk sleep shorts are the softest, most lightweight pair of pajama shorts my boyfriend owns. They are made from a thin, soft, stretchy material that creates a creamy, drapey feeling against the skin. The bamboo viscose and modal material is ultra-absorbent and quick drying at the same time. He sleeps through the night without sweating or overheating while wearing these shorts.

The shorts are flowy, roomy and breathable and have a thick waistband that doesn't annoyingly roll or bunch. One thing to note: You may want to size up if you're in between sizes, as they run a little small. The shorts are also plenty long, so you won't have to worry about it being too short if you go down a size.  

Material: 48% Bamboo viscose, 47% modal, 5% Lycra(R) spandex

Pros

• Ultra-thin, stretchy and silky-smooth 
• Lightweight and breathable 
• Pockets and drawstring

Cons

• Size up if you're in between sizes
• Unfit for everyday wear outside home

Some of the fun behind cooling pajamas is choosing from cute patterns and colors and mixing and matching. Z Supply is my favorite brand that does this well. You can easily match a piece from one collection with a piece from another. Not only does it offer some of the best stylish designs, but the fabric of all its products is soft and cloud-like. It is made of silky pointelle, a lightweight, breathable knit with eyelets that make a lacy pattern. 

One of my favorite pajamas pieces is the Tia Ditsy tank bra. It is extremely soft and light, with a beautiful flower pattern. It goes well with even some solid color shorts I already have in my closet. It's a comfortable, lightweight fabric that fits over the body well enough to offer support without uncomfortable clinging. They passed my breathability test with flying colors.

Material: Silky Pointelle: 95% polyester, 5% spandex  

Pros

• The material is silky soft and light 
• Lots of stylish patterns to choose from
• Tops and bottoms can be bought separately

Cons

• No larger sizes than an L
• Some lighter-color sets are transparent

The pajama sets from Tasc are great for guys who want quality, soft materials in basic colors and designs. My boyfriend likes simple clothing without extra frills, so he really enjoys the options from Tasc. There are only two materials and five colors to choose from. 

The Tasco Microluxe Rib sleep shirt is one of his favorites. It feels similar to the Cozy Earth set, but they're more soft than silky smooth. It's a comfortable, breathable fabric that drapes and flows over the body without uncomfortable clinging. My boyfriend says that it is cozy and, despite the long sleeves, not too hot. It is nice to sleep in because it is loose and comfortable. 

Material: 48% Modal, 47% polyester, 5% elastane

Pros

• Relaxed fit
• High-quality stretchy and silk-soft material 
• Doubles as casual loungewear 

Cons

• Material is a bit heavier than Cozy Earth
