Description
Nyth is a bamboo nightdress built for one thing: keeping you dry through the night, even when menopause night sweats have other plans.
You know the pattern. Soaked at 3am, freezing ten minutes later, sheets damp, sleep gone. Cotton holds the wet against your skin. Silk clings. Most "bamboo" is really polyester that traps the heat. Nyth is real bamboo lyocell, cut to skim rather than cling, so moisture moves away fast and the fabric dries before the cold sets in.
There's nothing to do and nothing to learn. Slip it on, go to bed, and wake up dry. From the very first night.
Specifications
Fabric: 100% Bamboo, breathable and quick-drying, OEKO-TEX certified
Cut: relaxed slip, thin straps, knee-length, anti-cling
Colours: Black, White, Pink, Grey
Sizes: S to XL (UK 8 to 22)
Care: machine wash cool, hang to dry. Softer with every wash.
Why it works
It was never really the heat that woke you. It was being wet, then cold. The flush leaves you soaked, the sweat cools on your skin, and the chill jolts you awake. Over and over, most of the night.
Cooling nightwear only fights the heat, so it leaves you shivering in your own sweat. Nyth works on both sides of the flush. The bamboo lyocell lifts moisture off your skin fast, then dries quickly, so the cold never gets its chance. That is exactly where cheap bamboo viscose fails: it feels cool for a moment but stays damp through the chill.
We won't tell you it stops the flush, because nothing you wear can. But it can stop the part that actually wrecks your sleep: waking up soaked and freezing. Your nightdress stays dry, your sheets stay drier, and you stay asleep.
Delivery & Guarantee
Free UK delivery on every order, tracked, usually 6 to 12 working days.
Every Nyth is covered by our Sleep Dry promise. Wear it for 60 nights. If you still wake up soaked and freezing, tell us and we'll refund you, every penny. The only thing you risk is one dry night's sleep.
Important
Nyth is real bamboo lyocell, sold only on this official website. Plenty of "bamboo" nightwear is really polyester or cheap viscose that traps the heat and stays damp through the chill. Those lookalikes aren't Nyth, and they don't come with our OEKO-TEX certified fabric, free UK delivery or 60-night Sleep Dry guarantee. Order here to be sure you get the real thing.

Loved by women who finally
sleep through the night, dry
★★★★★
Dry all night, first time in years
First night I wore it, I slept straight through and woke up dry. I honestly cannot remember the last time that happened. My sheets were dry in the morning too.
★★★★★
No more stripping the bed at 3am
I was changing my pyjamas and sheets most nights. Since this arrived the wet has nowhere to sit, so I stay put and go back to sleep. My laundry pile has halved.
★★★★★
Real bamboo, not the fake stuff
Cotton stayed damp against me and silk clung everywhere. This is proper bamboo, it moves the sweat away and dries fast. You can feel the difference straight away.
★★★★★
Honest about what it does
It doesn't stop the sweats, and it never claims to. What it does is stop me waking up soaked and freezing, which is the bit that was ruining my sleep. That's exactly what I wanted.
★★★★★
One on, one in the wash
Bought the two so there's always a fresh one ready. Best decision. I no longer panic when one is drying. Comfortable, and it actually looks nice too.
★★★★★
I feel like myself again
I'd stopped buying nice nightwear years ago. This is soft, it flatters, and I no longer feel damp and horrible next to my husband. Small change, huge difference to how I feel.
Not all bamboo is bamboo
Most "bamboo" nightwear is really polyester or cheap viscose with a bamboo label. Here is what makes Nyth different, and why it matters when you are sweating at 3am.
Real bamboo fibre
Nyth is made from genuine bamboo, not polyester blended with a trace of bamboo and sold as the real thing. Bamboo fibre is naturally soft, breathable and moisture-wicking, which is why it works for night sweats. The cheap alternatives feel similar in the shop but fail when you actually need them: they trap heat, hold sweat and stay damp.
OEKO-TEX Standard 100
Every Nyth nightdress is OEKO-TEX Standard 100 certified. That means the fabric has been independently tested for over 100 harmful substances, including pesticides, heavy metals and formaldehyde. It is the most trusted textile safety certification in the world, and it means you know exactly what is touching your skin all night.
Wicks and dries, both sides
Most fabrics do one or the other. Cotton wicks but stays damp. Polyester dries but traps heat. Real bamboo does both: it pulls moisture off your skin quickly, then dries fast so the chill never sets in. That is the whole mechanism behind staying dry through a flush, not just during it, but after it too.
Why it matters at 3am
The fabric you sleep in decides whether you wake up soaked or stay asleep.
What most nightwear does
✕ Cotton holds sweat against your skin
✕ Polyester traps heat, then stays damp

What Nyth does
✓ Wicks sweat off your skin fast
✓ Dries quickly, so the cold never sets in
✓ Skims your body, never clings when damp
✓ OEKO-TEX certified, tested for 100+ substances
When the sweat comes, stay dry and sleep straight through it
Soaked at 3am, freezing ten minutes later, up stripping the bed again. Nyth lifts the sweat off your skin and dries fast, so the wet has nowhere to sit and the cold never gets its chance. You stay put, and you stay asleep. From the very first night.
No cooling gimmicks. No fake bamboo. Just dry.
Made for the women menopause turned into strangers. We won't promise to stop your flush, because nothing you wear can. What we promise is real bamboo that keeps you dry through it, in a nightdress you'll actually want to wear, not another cooling gadget that leaves you shivering in your own sweat.

It was never the heat that woke you
Every cooling brand fights the heat. But the heat is not what wakes you. What wakes you is being soaked, then freezing, over and over, most of the night. Cooling nightwear does nothing for the cold that follows the sweat. Drying does. That is the whole idea behind Nyth.
The soak-and-freeze loop
The sweat leaves you drenched. It cools on your skin, the chill jolts you awake, and then it happens again. It is the wet-then-cold loop, not the heat, that fractures your sleep.
Wicks it away fast
Real bamboo lifts the moisture off your skin quickly, so you are not left lying in the wet. That is the first half of staying dry, and it is the half cotton gets wrong: it just holds the damp against you.
Then dries fast
And it dries quickly, so the cold never gets its chance to set in. This is the half cooling nightwear misses, and where cheap fake bamboo fails: it feels cool for a moment but stays damp through the chill.
How Nyth keeps you dry, both sides of the flush
It works on the whole cycle, not just the heat.

Frequently Asked Questions
Everything you might be wondering, answered honestly.
It works because of what it does with the sweat, not by cooling you down. Real bamboo lifts the moisture off your skin fast, then dries quickly, so you are not left lying soaked and then freezing. That soaked-then-cold jolt is the thing that keeps waking you. Take it away and most women sleep straight through. If it does not do that for you, you have 60 nights to send it back for a full refund.
No, and we will never pretend it does. Nothing you wear can stop a flush. What Nyth does is stop the part that actually ruins your sleep: waking up soaked and freezing. The flush may still come, but you stay dry through it, so you stay asleep. Being honest about this is exactly why our customers trust the rest.
Cotton absorbs the sweat and then holds it against your skin, so you stay wet and cold. Silk dries faster but clings to everything. Real bamboo does both jobs: it wicks the moisture away and dries quickly, and it is cut to skim rather than cling. That is the whole difference between waking up damp and waking up dry.
Real bamboo, and OEKO-TEX certified so you know it has been tested for harmful substances. A lot of "bamboo" nightwear is really polyester or cheap viscose that traps heat and stays damp through the chill. That is the opposite of what you need. Nyth is made from genuine bamboo, which is why it feels naturally soft and breathable against your skin.
Usually the very first night. There is nothing to set up, nothing to charge and nothing to learn. You slip it on, go to bed, and wake up dry instead of soaked. Most women tell us their sheets stay drier too.
Choose by your bust measurement in cm, not by the letter or your usual dress size. Measure around the fullest part of your bust and pick the size that covers your number. We go from S (UK 6-8) to XXL (UK 14-18). If you are between two sizes, size up for extra comfort. Not sure about UK sizes? The bust measurement works the same in any country. Our 60-night guarantee covers fit too, so you can try it with nothing to lose.
Four: black, white, pink and grey. All in the same real bamboo, cut the same relaxed way. Most women go for the three-pack so there is always a fresh one ready while the others are in the wash.
Because you are likely washing nightwear far more often than usual right now. Keeping three in rotation means there is always a dry, fresh one ready while the others are in the wash, so you are never caught out in the middle of the night. It also works out at just £23 each instead of £39, which is why the three-pack is our most popular option.
Machine wash cool and hang to dry. Cared for that way, it holds its shape and its quick-drying feel, and it actually gets softer with every wash. Avoid a hot wash and fabric softener, which coat the fibres and reduce how well it moves moisture.
That is a big part of the point. When you are not lying in sweat, you do not feel clammy and self-conscious. Nyth is soft, it flatters, and plenty of women tell us it is the first nightwear in years they have felt good wearing, rather than something they just put up with.
Free UK delivery on every order, fully tracked, usually within 2 to 4 working days. You will get tracking by email as soon as your order is on its way.
Then you get your money back. Wear it for up to 60 nights. If you still wake up soaked and freezing, tell us and we will refund you in full. The only thing you risk is one dry night's sleep.
