What lands in the first drop

Two sets, $84

One to wear, one in the wash, because a bad night shouldn't cost you a clean set. Add a second Cool Set and $12 comes off automatically.

It isn't falling asleep. It's staying asleep.

  1. You go down fine. Your body starts dropping the degree or so it needs to keep you under.

  2. Heat has nowhere to go. Polyester is holding it against you, cotton has soaked up the damp and is still wet. You're awake, and now you're doing the duvet maths.

  3. You never properly went back down. Tomorrow you'll be told to try magnesium.

The layer closest to your skin decides it

Nothing to swallow, nothing to plug in, nothing that takes eight weeks to maybe work. Just the fabric touching you while you sleep, which is the one variable most pajamas get wrong.

So that's all we make.

What each fabric does once you're warm and damp at 3 a.m.
FabricWhat happens
Polyester and fleece Holds heat and sweat against your skin and won't let either leave. Most pajamas sold as cosy are this.
Heavy cotton Breathes, but soaks the damp up and then stays wet for hours. Fine at 11 pm, cold and clammy by 3 am.
Viscose made from bamboo Light enough to let air through, and it moves moisture off your skin to the surface where it can dry. This is what we use: 95% viscose made from bamboo, 5% spandex.

New colours, restocks and the next drop go to the list first, before they're on the site. You also get the Cool Night Checklist: nine free ways to make a bedroom colder.

One or two emails a month. Unsubscribe any time. We don't sell or share your email.

  1. Set the bedroom to 65 to 68 degrees.
  2. Swap the duvet for two light layers you can kick off one at a time.
  3. Get polyester and fleece out of the bed entirely.
  4. Keep a glass of cold water within reach.
  5. Put a fan where it moves air across you, not at you.
  6. Finish wine and spicy food three hours before bed.
  7. Take a warm shower, not a cold one. Your body cools itself afterwards.
  8. Keep a dry top by the bed, so a bad night costs you two minutes instead of forty.
  9. Wear something that breathes. That part is our job.

Answers, including the unhelpful ones

What is the Founding 100 offer?

The first 100 orders get 15% off with code FOUNDING15, on top of free US shipping. One use per customer. When the 100 are gone we'll say so on the site rather than quietly keep running it.

Will this stop night sweats?

No. Clothing can't do that and we're not going to pretend otherwise. It is lighter, more breathable and quicker to dry than what you're probably wearing, so you're more comfortable when you run hot. That's the whole claim.

How does it fit?

Cut roomy on purpose, because air needs to move. If you're between sizes, size down. Full measurements are on each product page.

Where does it ship from, and how fast?

A warehouse in the United States. Orders leave in 1 to 2 business days and arrive 2 to 5 business days after that. Shipping is free on every US order.

What if the size is wrong?

You have 30 days from delivery to return it unworn with the tags on. Email hello@stillcoolsleep.com or reply to your order confirmation to start a return.

Still you. Still cool.

We started Still Cool because the women we know are running companies, raising teenagers and looking after their parents, and doing all of it on four hours of broken sleep.

Nobody needs a lecture, a supplement subscription or a word like "journey." You need better pajamas, and someone to be straight with you about what they will and won't fix.
