Why people switch

Loved by hot sleepers, covered by the press

Real reviews from people who sleep hot, and fifteen years of coverage in the national press.

★★★★★5 out of 5 stars

Very cozy shirt

I am enjoying the sweat staying away from my body. Sleeping in my new cozy shirt with long sleeves lets me have my upper body out of the covers and still warm.

★★★★★5 out of 5 stars

Finally - the men's models are back. My old shirt was getting thin.

I had been wondering what happened to the men's models of cool-jams. Only just discovered that they were back from a female relative who also enjoys your pajamas. Took over a week to get here (Ottawa, Canada) but they are the same excellent quality as my original.

So Far So Good

I’ve worn the nightgown for about a week and have not had to get up to change in the middle of the night because of sweating. Recommend.

The return of the great long tank gowns!

The material is just like it used to be, sleek and cooling. The scoop neck is actually a scoop again with nice roomy armholes. Thank you, Cool-jams for returning to your roots.

★★★★★5 out of 5 stars My mom loved them she said they’re cute and keep her cool. She likes it cause she can even wear them and they don’t look like pajamas

Much Improved Over Last Season

The new material that you are using is far superior to what you were using just one year ago. This nightgown is very comfortable, soft and lightweight and a perfect length for me. Thank you!

Love my cool Jams

I bought a pair of cool jams a few years ago and have loved them since. I wanted/needed another pair of PJ's and cool jams is exactly what I wanted. I love the soft colors and the feel of the fabric...and they wick moisture away perfectly when needed. If UI get another pair, they definitely will be Cool Jams.

Cooling sleepwear, answered

Quick answers about our cooling pajamas, nightgowns and sleep shirts for women and men. For sizing, shipping and returns, see the full FAQ.

Read the full FAQ

What makes Cool-jams cooling sleepwear different?

NightCool is our best fabric for cooling sleepwear. Behind it is Kottinu, a performance microfiber made for firefighter base layers and medical scrubs, now breathable cooling pajamas for hot sleepers and night sweats. The fibre is spun from filaments finer than a human hair. It pulls sweat off your skin, spreads it out, and dries fast, so heat leaves with the moisture. Read the science behind Cool-jams sleepwear.

What is a technical synthetic, and how does it cool you down?

A technical synthetic is a fibre engineered for a job rather than chosen for cost. Kottinu was developed for firefighter base layers worn under turnout gear and for medical scrubs, where staying dry through a long shift is the entire point. That is the fibre NightCool is made from.

Three things do the work, and none of them is the fibre’s name. The filaments are spun finer than a human hair, which gives moisture far more surface to travel along. Several are twisted together, so moisture moves out along the thread instead of pooling where it landed. And the knit is built open enough for air to reach that moisture and carry it away.

The result is a three step process: sweat is pulled off your skin, spread across the outer surface, then evaporated into the air, and body heat leaves with it. That is what keeps it working through the night rather than only feeling cool the moment you touch it. [Read the science behind Cool-jams sleepwear](/content/pages/the-science-behind-cool-jams-sleepwear ""/index.html).

Isn’t polyester the wrong fabric if you sleep hot?

It depends entirely on how it is built. Heavy, tightly woven polyester does trap heat, which is where that advice comes from. NightCool is the opposite construction: an ultrafine filament knitted open enough to move air, so moisture is carried to the surface where it can evaporate instead of sitting against your skin. Breathability comes from the knit, not from the fibre’s name.

If you are comparing fabrics, look at construction rather than the fibre name: a loose cut so air can move, a knit that carries moisture outward rather than holding it, and a fabric that dries quickly so you are not lying in damp cloth once a sweat passes.

What cooling sleepwear for women do you make?

Most of the line. Cooling pajama sets, cooling nightgowns and nightshirts, plus tops and bottoms you can mix yourself, all in NightCool. Start with women’s cooling sleepwear, or go straight to cooling pajama sets or cooling nightgowns for women.

Do you have cooling sleepwear for men?

Yes. Men’s sleep shirts, pajama tops and pajama bottoms, all in the same NightCool fabric. Shop men’s cooling sleepwear.

Is this menopause sleepwear? Will it help with night sweats?

Menopause is why most of our customers find us, and NightCool is what we point them to. It cannot stop a hot flash, but it moves the sweat off your skin and dries fast, so a rough moment is less likely to end in a soaked shirt and a sheet change. Shop menopause sleepwear for night sweats.

Why does it feel like cotton if it is synthetic?

Because the fibre is a microfiber, spun far finer than standard polyester yarn and knitted for a soft hand rather than a slick one. Cotton-level softness without the sticky feel of many synthetic wicking fabrics. That cotton feel was the whole design brief.

Will the cooling wash out over time?

No. The wicking comes from the fibre and the knit structure, not from a coating, so there is nothing to rinse away. Just skip fabric softener and dryer sheets. They leave a film that blocks moisture transport, and a re-wash in clear water brings the wicking back.

Can I sleep in it first?

Yes. That is the 30-Night Cool Sleep Trial. Sleep in your NightCool items, wash them, and if they are still not right, start a return within 30 days of delivery. Worn and washed is fine. See how the trial works.

Why can't sweat stay in this fabric?

Cotton drinks. Cotton is cellulose, and cellulose is studded with hydroxyl groups: molecular docking points that hydrogen-bond with water. A lovely hand when dry. But once you sweat, the water is bonded inside the fibre itself, and it stays.

Our polymer refuses. The Kottinu filament is a polyester polymer with no docking points to offer. Water cannot soak into the fibre and nothing about it invites water to stay. So moisture is left with one option: it has to move.

The channels decide where. Bundle filaments finer than a human hair and the gaps between them become capillary channels. The narrower the channel, the stronger the pull, so sweat is drawn off your skin, along the thread, and handed to the air.

No coating, no finish, nothing to wash out. The mechanism is the geometry of the yarn and the chemistry of the polymer itself.
