Meet Simone — the nightgown that finally works.

If you've already tried bamboo, cotton, or "cooling" fabrics and woken up drenched anyway, you're not alone — and you're not out of options.

Simone is made from our signature hemp-cotton blend, specifically chosen because hemp naturally pulls heat and moisture away from your body all night long. No synthetics. No chemical coatings. No waking up at 3 a.m. to change your pajamas.

Women who've tried everything tell us the same thing: "I finally slept through the night."

What's included with every Simone:

✓ The Simone Nightgown Breathable, moisture-wicking, and naturally anti-bacterial — designed specifically for women with night sweats.

✓ Night Sweats Tracking e-Journal — free with every order A printable tool to help you identify your personal triggers and sleep better, faster.

✓ Our 60-Night Guarantee Wear it, wash it, sleep in it for two full months. If it doesn't work for you, we'll refund every penny. No awkward questions.

By day, Simone doubles as a wrinkle-resistant travel dress, beach cover-up, or weekend outfit. She doesn't cling, never smells, and gets softer with every wash.

Hundreds sold. Fewer than 10 returns. The nightgown that finally works.

Night Sweats Tracking e-Journal

Included with every purchase.

It may seem a little strange to keep track of everything you do, eat, and drink (or don't drink) during your waking hours, but it can help you identify the things that are making your night sweats worse.

Our printable tracking journal can help prompt your memory, or look back on a week's worth of data to help you identify the things that are triggering your night sweats. While caffeine, alcohol, and warm tea right before bed, are common triggers, everyone is different and different things will trigger your body into reacting.

Once you have a handle on what is making your night sweats worse, you can start eliminating or shifting them (ie., drink your tea an hour and a half before bed, exercise before dinner...) to improve your sleep.

It will help you track:

  • Exercise 
  • Food and beverages 
  • Overall sleep hygiene
  • Sleep environment

Simone's FAQs

I've tried other cooling sleepwear and it didn't work — why would the Simone be different?

Most cooling sleepwear fails for one reason: it absorbs moisture but doesn't release it quickly enough. Bamboo and cotton feel great at bedtime, but once they're wet, they hold on — leaving you damp, then cold, then wide awake.

Hemp behaves differently. Its hollow fibre structure pulls moisture away from your skin and lets it evaporate quickly — so the fabric doesn't stay wet against you. It also stores a small amount of heat and releases it back during the chill phase, which is what most sleepwear completely ignores.

That's the difference. Not a coating, not a marketing claim — the physical structure of the fibre.If you're not convinced, you shouldn't have to take our word for it.

That's why we offer a 60-night guarantee — wear it, wash it, sleep in it, and decide for yourself.

Does the Simone Nightgown really help with night sweats and hot flashes?

Yes — that’s exactly what it was made for. The Simone’s temperature-regulating, moisture-wicking fabric quickly absorbs and releases moisture, helping prevent that clammy, wake-you-up feeling caused by night sweats and hot flashes. It helps your body maintain a comfortable balance so you can actually rest through the night.

Can I wear the Simone Nightgown as both sleepwear and a day dress?

Yes! The Simone is as versatile as it is functional. It transitions easily from cooling sleepwear at night to a wrinkle-resistant day dress or bathing suit cover-up during the day. It’s soft, breathable, and stylish enough to wear from bed to brunch and everywhere in between.

Will Simone work if my night sweats are severe?

For most women, yes — including women with significant night sweats. The hemp-cotton fabric works harder than most sleepwear at moving moisture away from your skin and managing the temperature swing that follows a hot flash.

That said, we'll be honest with you: if your night sweats are severe, the Simone works best as part of a full sleep system. If your sheets, blanket, or mattress cover are trapping heat and moisture, even the right sleepwear has to work against them.

Switching one layer helps. Getting the layers to work together helps more.

We include a Night Sweats Tracking Journal with every order to help you identify what's making your symptoms worse — because fabric is one piece of the puzzle, not the whole answer.

And if you try it and it's not enough? Our 60-night guarantee means you can return it for a full refund, no awkward questions. Fewer than 10 women have ever taken us up on it.

CoolYourSweats' Promise

The CoolYourSweats Difference

Here's the reality: the majority of apparel manufacturers use fabric that is inadequate to handle the unique needs of women with hot flashes or night sweats.

That's why we set out to disrupt the apparel market by using a natural, hemp/organic cotton blend that was selected specifically to manage hot flashes and night sweats.

Our fabric was tested and selected based on our founder's personal experience with night sweats. She used her professional expertise with natural materials to find the right fabric to manage heat and moisture.

The result is that we are the ONLY hot flash clothing providers using hemp blends to help women stay comfortable through a hot flash.
