Let's just say it: somewhere around 2 a.m. you woke up, and your pyjamas had officially given up on you. The sheets are damp. You've kicked off the duvet, but somehow you're also cold. By the time you drift back to sleep, it's almost 4.
If that made you nod a little too hard, welcome. You're in very good, very sweaty company. Night sweats and hot flashes affect the large majority of women going through perimenopause and menopause, according to Chatelaine's coverage of research from The Menopause Society. And most pyjamas aren't built for the job. Cotton gets heavy and clingy the second it's damp. Synthetic blends trap heat like a sauna you didn't sign up for.
The short answer: the best pyjamas for night sweats are loose-fitting, made from moisture-wicking fabric that pulls sweat away from your skin, and easy to wash, because you'll wash them often. For most women, that means bamboo. It won't stop a hot flash, but it can shorten the wet-then-cold cycle that keeps you awake.
What Causes Night Sweats?
For most women in their 40s and 50s, night sweats are vasomotor symptoms: the same biology behind daytime hot flashes, triggered at the worst possible time. As estrogen shifts, the hypothalamus (your body's thermostat) becomes more sensitive to tiny changes in core temperature. Your brain reads a small rise as overheating and triggers a sweat to cool you down, which often leaves you chilled minutes later.
According to the Mayo Clinic, estrogen fluctuations are the main driver of hot flashes and night sweats in menopause. Research published in the journal Menopause found about 80% of women experience vasomotor symptoms during the transition, with night sweats affecting close to 60%.
Night sweats can also be triggered by some medications, thyroid changes and a warm bedroom. Not sure which stage you're in? Here's what's actually different between perimenopause and menopause.
Why Bamboo Works: The Readable Science
Your core body temperature naturally drops as you fall asleep, and staying cool is one of the most important conditions for deep, restorative sleep. When your fabric traps heat, your body works harder to cool down, and you wake up.
Bamboo viscose, the star of our Georgia Rylan collection, has a naturally porous fibre structure. It breathes, it wicks moisture away from your skin and releases it through the fabric, and it dries faster than cotton. That's built into the fibre itself, not a chemical coating, which is why bamboo keeps its cooling properties wash after wash. It's also temperature-adaptive, keeping you warm when the room is cool and cool when you're not. If you've hit this stage of life, you know that's the whole ballgame.
Curious how it stacks up? See bamboo vs. cotton: which one actually helps with night sweats, or learn what makes bamboo fabric so soft in the first place.
Our bamboo is a 95% bamboo viscose and 5% spandex blend, OEKO-TEX® STANDARD 100 certified, so every component has been tested for harmful substances. It's also naturally gentle on sensitive skin, so if hot flashes have made you more reactive to fabric lately, that's one less thing working against you. Here's what OEKO-TEX® certified means, in plain language.
What to Look for in Cooling Pyjamas
1. Moisture-wicking fabric (the non-negotiable)
This is the most important decision in this whole guide. Cotton absorbs moisture and holds it against your body, which is why you wake up cold and damp. Bamboo moves it away so it can evaporate.
2. A relaxed, not oversized, fit
You want airflow without extra fabric bunching against damp skin. Fitted styles trap heat, and very loose styles twist and tangle at 3 a.m. The sweet spot is a relaxed silhouette with no elastic that digs in.
3. Minimal construction details
Seams and tight waistbands feel worse when you're overheated. Skip flannel, fleece, heavy cotton jersey and anything brushed or plush on the inside. They feel cozy right up until you overheat.
4. Machine washable and durable
The fabric needs to keep its softness, its wicking and its shape through lots of cold washes. With proper care, bamboo actually gets softer with every wash.

Our Favourite Georgia Rylan Pieces for Night Sweats
Every piece below is OEKO-TEX® certified bamboo, designed in Edmonton, sized XS to 3XL, true to size, and available exclusively at Cloud Nine Pajamas.
Best overall: Bamboo V-Neck Nightshirt with Pockets
One piece, no decisions. The V-neck reduces fabric at the throat, one of the most heat-sensitive areas during a hot flash. Short sleeves let your arms breathe, the relaxed shape doesn't cling or twist, and two deep pockets are a detail most nightshirts skip.
→ Shop the V-Neck Nightshirt with Pockets
Best if you run cold between sweats: Bamboo Button-Up Long Sleeve Nightshirt
Long sleeves for night sweats sounds backwards, but bamboo changes the math. It wicks the full length of the sleeve, and the button front opens all the way during a hot flash without taking it off. It also wears beautifully open as a lightweight morning layer.

Best for consistently warm sleepers: Bamboo Tank & Short PJ Set
Minimum coverage, maximum wicking. The scoop-neck tank keeps fabric off your throat, the 4" inseam shorts stay put, and the drawstring waist won't dig in.
Best nightgown: Flutter Dress Nightgown
The flutter sleeve covers your shoulders for when you get chilly, without fabric along the upper arm where heat builds up. The box-pleated front keeps fabric away from damp skin, and the above-the-knee length never tangles.
→ Shop the Flutter Dress Nightgown
Best for layering: Essential Bamboo Tank + Essential Bamboo Tee
Build your own system: the tank as a cooling base and the tee for when you need a little more warmth. Both work as daywear too.

And for him
Bamboo isn't just for the women in the house. Bob's Sleepwear Co. is made for the man who's done with scratchy waistbands and overheating by 11 p.m. Here's how bamboo helps men with night sweats and snoring.
How to Wash Bamboo So It Keeps Working
- Machine wash cold on a gentle cycle. Hot water breaks down bamboo fibres faster.
- Hang or lay flat to dry, or tumble dry on low. High heat is the quickest way to shorten its life.
- Skip the fabric softener. It coats the fibres and reduces wicking. Bamboo is already soft.
- No bleach. Cold water and a gentle detergent are all you need.
- Wash prints inside out to keep colours vibrant.
When to Talk to Your Doctor
Night sweats during perimenopause and menopause are normal, but it's worth a conversation with your doctor if they're drenching your clothes and sheets regularly, if they're new and you're outside the typical menopause age range, if they come with unexplained weight loss or fever, or if they're affecting how you function during the day. A doctor can rule out other causes and talk through options like hormone therapy. The right pyjamas help, medical support helps more, and the two work beautifully together.
Night Sweats FAQ
Are bamboo pyjamas really better than cotton for night sweats?
Yes. Cotton absorbs moisture and holds it against your skin. Bamboo wicks it away so it can evaporate, so you dry faster after a hot flash and get back to sleep sooner. Over several episodes a night, that adds up.
Is bamboo sleepwear good for sensitive skin?
Yes. Bamboo is naturally gentle and our Georgia Rylan bamboo is OEKO-TEX® STANDARD 100 certified, a good choice if hot flashes have left your skin more reactive than usual.
What size should I order?
Georgia Rylan is true to size, XS to 3XL (Canadian sizing: XS 0–2 · SM 4–6 · MD 8–10 · LG 12–14 · XL 16–18 · 2XL 20–22 · 3XL 24–26). Between sizes? Size up for nightshirts and nightgowns. See the Georgia Rylan Size Guide for full measurements.
Can I wear these as daywear?
Yes. The Essential Tank and Tee are designed for daywear, and the nightshirts are lovely around the house in the morning.
Where can I buy Georgia Rylan in Canada?
Georgia Rylan is available exclusively at Cloud Nine Pajamas, in our three Edmonton-area boutiques and online, shipping across Canada.
The Bottom Line
You deserve sleep that doesn't feel like a negotiation with your own body. The fabric is the decision: bamboo, moisture-wicking, OEKO-TEX® certified and easy to care for. Everything else is personal preference. If you're not sure where to start, the V-Neck Nightshirt with Pockets is the right first piece for most women, and our team at any of our three locations would love to help you find yours.
