Size guide

Measure your body and find the band you fall into. Between two sizes, we suggest sizing up, because sleepwear is more comfortable a little looser.

Wake up cool and dry. The Cool-jams Women's NightCool Scoop Neck T-Shirt with 3/4 Sleeves is a cooling sleep shirt built for hot sleepers and for nights when you run warm. This moisture-wicking sleep shirt is made from our proprietary Kottinu fabric, which pulls perspiration off your skin as it forms and dries fast, so you stay comfortable all night.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.

More about the Scoop Neck T-Shirt - 3/4 Sleeves

The Cool-jams NightCool Scoop Neck T-Shirt with 3/4 Sleeves is made for warm sleepers and warm nights that do not stay one temperature. The three-quarter sleeve covers the upper arm and stops clear of the wrist, so you are not pushing fabric up all night, and the scoop neck keeps the chest open. Kottinu fabric wicks sweat and dries fast, and an odor-control finish helps the fabric stay fresher between washes. Designed to mix with any NightCool bottom, in Black, Navy and Merlot, in sizes S to 3X.

What is a 3/4 sleeve?

It ends between the elbow and the wrist, covering the upper arm while leaving the forearm free.

Is this warmer than the short sleeve version?

Slightly, because of the extra sleeve, but the fabric is identical and still wicks and dries fast.

Does it match the NightCool bottoms?

Yes, the solid colors are shared across the NightCool range so tops and bottoms can be mixed.

Why you'll love it

Flattering scoop neckline with a relaxed, non-cling fit
3/4 sleeves for comfortable coverage without overheating
Kottinu moisture-wicking fabric that wicks perspiration and dries quickly, engineered for night sweats and hot flashes
Soft, cotton-like texture that resists pilling and holds its shape
Bact-Out finish helps the fabric stay fresher between washes

What is Kottinu?

Kottinu, a technical synthetic (engineered polyester microfiber) made for firefighter base layers and medical scrubs, now crafted for hot sleepers and night sweats needing moisture-wicking and cooling pajamas. Soft and smooth with a cotton-like feel, it pulls sweat off your skin, dries fast, carrying body heat away with it.

A Bact-Out finish helps the fabric resist odor, so it stays fresher between washes. Kottinu resists pilling, holds its shape, and machine washes easily.

How to care for Kottinu

Machine wash cold or warm with like colors, gentle cycle
Skip fabric softener and dryer sheets, they coat the microfibers and can reduce wicking
Tumble dry low or hang to dry, Kottinu dries fast
No bleach
Holds its shape and resists pilling wash after wash

The 3 AM test: cotton or NightCool?

Same sweat. Different night.

	NightCool	Cotton
Sweat on your skin	Pulled off you. Dry fast.	Soaks in and stays.
Odor	Bact-Out finish, so the fabric stays fresher	Nothing in it to help
After the wash	Holds its shape, no pilling	Pills with wear
By 3 AM	Dry	Damp

Try it for 30 nights. Not cooler? Send it back. How the trial works

Women's DayBasics Scoop Neck Pajama Set - 3/4 Sleeves
Rated 5 out of 5 stars
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.

They aren't the same material as we prior purchased 2 pair. They feel too heavy for cool jams. I won't be purchasing again.

Marilyn, thank you for telling us, and we are sorry. If it is the cooling performance fabric you are after, that is our NightCool line, made with our Kottinu fabric that pulls moisture off the skin and dries in minutes. This set is from DayBasics, our softer everyday line, which is a different fabric. We are pulling up your past orders now, and someone from our team will contact you very soon to work out exactly what you had before and get you back into the right one. We would hate to lose you after all these years.
