The Best Pajamas for Sleep: What to Look For

Posted by Cli Westbrook on July 06, 2026

There is something sacred about the moment you slip into bed — the weight of the day lifting, the sheets cool against your skin, the room quiet. What you're wearing in that moment matters more than most people realize. The best pajamas for sleep are made from breathable fabrics, such as TENCEL™ Modal or natural cotton, in a relaxed fit. What you wear to bed shapes how comfortable you feel as you drift off, through the night, and when morning light finally arrives. When the fabric is right, the question of whether to go to bed stops being a negotiation.

What Your Pajamas Are Actually Doing While You Sleep

Your body doesn't simply switch off at night. According to the Sleep Foundation, core body temperature starts to drop about two hours before you go to sleep. A review in Frontiers in Neuroscience notes that people try to keep the microclimate next to their skin between 31 and 35°C, and that straying from that range affects sleep.

Feeling neither too warm nor too cool is a big part of sleeping well, and the Sleep Foundation puts the best bedroom temperature at about 65 degrees Fahrenheit. A breathable fabric is a simple place to start.

Which Fabrics Are Best for Sleep?

TENCEL™ Modal: The Everyday Favorite

TENCEL™ Modal — a fiber made by Lenzing from wood sourced from responsibly managed forests — has become one of the most considered fabrics in sleepwear, and for good reason. Eberjey's TENCEL™ Modal knit is breathable and temperature-regulating, helping you stay comfortable through the night. It is also buttery soft and gentle on skin, and the Gisele TENCEL™ Modal Long PJ Set is verified by OEKO-TEX® Standard 100.

Its smooth, silky hand is a big part of its appeal.

Eberjey's Gisele TENCEL™ Modal Long PJ Set has more than 1,400 five-star reviews. It is relaxed, breathable, and hard to change out of come morning.

Cotton: Breathable, But Not All Cotton Is Equal

Pima is an extra-long-staple cotton grown in places including Peru and the American Southwest, and Supima, the American Pima brand, describes it as softer and stronger than regular cotton. For those who prefer cotton, long-staple or certified organic varieties are worth seeking out.

Silk and Washable Silk: Luxurious and Thermoregulating

Silk is a natural protein fiber. Eberjey's Washable Silk is made from 100% mulberry silk, and the Inez Washable Silk Long PJ Set is described as hypoallergenic and thermoregulating, offering comfort year-round. Eberjey's washable silk sleepwear can be hand washed or machine washed cold on a delicate cycle — a genuinely wearable choice for every night, not just special occasions.

What to Avoid

Heavy fabrics that trap heat can leave you too warm. If you sleep hot, choose something breathable.

How Should Pajamas Fit for Sleep?

Fit is mostly about comfort. Pajamas that feel tight can be hard to settle in, and very loose pajamas can bunch, twist and ride up.

The ideal fit for sleep is relaxed without being shapeless: enough room to move freely through every sleeping position without excess fabric gathering. Long-sleeve tops should not pull across the shoulders when you raise your arms. Pants should have a soft, adjustable waistband that settles comfortably when you're lying down.

Eberjey designs its sleepwear to be roomy enough for ease and considered enough to feel intentional. The Gisele set's relaxed button-front top with a notch collar and its straight-leg pant are made for sleeping in, not just for how they look on a hanger.

Should You Wear Pajamas at All? Does Sleeping Naked Help?

This question comes up often, and the science is more nuanced than the popular claim that sleeping naked is always the answer. Staying cool does matter: the body's core temperature naturally drops in the evening as it prepares for sleep.

But what matters is the mechanism: temperature regulation, not the absence of fabric. A breathable fabric lets you stay comfortable while offering things bare skin cannot, like warmth on cooler nights and ease for people who prefer not to sleep unclothed.

The pragmatic answer: wear what allows you to fall asleep and stay asleep most consistently. For many people, that means lightweight, breathable pajamas.

What About Temperature Regulation for People Who Sleep Hot?

Around menopause, the U.S. Office on Women's Health notes that hot flashes can make you sweat while you sleep, and suggests dressing in layers and keeping the bedroom cool.

For hot sleepers, the priorities are clear:

Fabric first: TENCEL™ Modal or Washable Silk. Eberjey describes both as temperature-regulating.

Loose fit: Allows air to circulate between fabric and skin.

Lighter layers: A short-sleeve top or sleeveless set with the option to layer a robe if the room turns cool.

OEKO-TEX certification: Confirms the textile has been tested for harmful substances.

Eberjey's Gisele TENCEL™ Modal Short Sleeve Cropped PJ Set checks two of those boxes: a temperature-regulating fabric, verified by OEKO-TEX® Standard 100.

How Often Should You Wash Your Pajamas?

Wash them regularly and follow the care label.

TENCEL™ Modal is machine-washable on a gentle cycle and its fibers are made to withstand repeated washing and drying.

What Are the Best Pajamas for Different Seasons?

Warm Months and Warm Climates

Lightweight TENCEL™ Modal short sets or sleeveless options with wide-leg pants. Look for minimal construction — fewer seams, lighter fabric weight, open necklines. The goal is maximum airflow with enough coverage to feel effortlessly at ease.

Cool Months and Cooler Climates

Long-sleeve Modal sets or brushed cotton options add warmth without bulk. Layering a lightweight robe over Modal pajamas provides adjustable warmth you can shed during the night if your temperature rises.

Year-Round Versatility

A TENCEL™ Modal long set like the Gisele, which Eberjey calls an all-season staple, is an easy choice year-round.

What to Look for in Pajamas for Sleep

The criteria are simpler than the options make them seem. Begin with fabric: TENCEL™ Modal, high-quality cotton, or natural silk — breathable and smooth against skin. Look for OEKO-TEX Standard 100 certification, which confirms the fabric has been tested for harmful substances. Choose a relaxed fit, free of tight waistbands and constricting seams. Reach for fabrics that hold their softness through frequent washing — because pajamas that feel supremely soft on day one and day three hundred are the ones that become genuine wearable heirlooms. And choose weight and coverage based on how you actually sleep, not how the fabric looks folded on a shelf.

Sleepwear is one of the most direct investments you can make in how you feel — not just at night, but in the morning light that follows.

Frequently asked questions

What are the best pajamas for sleep?

Look for breathable fabrics like TENCEL™ Modal, high-quality cotton or silk, in a relaxed fit with no tight waistbands. These help you stay comfortable as your body naturally cools in the evening. Lighter weights suit warm sleepers, while long sets work for most of the year.

Does fabric really affect how well you sleep?

Fabric affects how comfortable you feel at night, and comfort matters for sleep. According to the Sleep Foundation, core body temperature starts to drop about two hours before sleep, so fabrics that trap heat can leave you feeling too warm. The Sleep Foundation puts the best bedroom temperature at about 65 degrees Fahrenheit.

Is TENCEL™ Modal good for sleep?

Many people love TENCEL™ Modal for sleep. Eberjey's Gisele TENCEL™ Modal knit is buttery soft and temperature-regulating, and the Gisele TENCEL™ Modal Short Sleeve Cropped PJ Set is verified by OEKO-TEX® Standard 100. It is also machine washable and made to hold up to repeated washing.

Is it better to sleep naked or wear pajamas?

What matters most is staying comfortably cool. A breathable, temperature-regulating pajama set can keep you comfortable while adding warmth on cooler nights. Wear whatever helps you fall asleep and stay asleep most consistently.

What pajamas are best for hot sleepers?

Hot sleepers often do best in TENCEL™ Modal or Washable Silk, in a loose fit and a lighter weight, such as a short-sleeve top or short set. Keeping a robe nearby lets you add a layer if the room cools down.
