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.

Bust	30.5–33.5	34–36.5	37–39.5	40–42.5	43–45.5	46–48.5

Body measurements, in inches. Dress and international sizes are size labels, so they do not change with the unit switch.

Garment laid flat and measured across. Not body measurements. Compare these with a garment you already own that fits you well.

Wake up cool and dry. The Cool-jams Women's NightCool Long Sleeve T-Shirt 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 and dries fast, so you stay comfortable all night.

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

More about the Long Sleeve T-Shirt

The Cool-jams NightCool Long Sleeve T-Shirt covers the arms without the heat that usually follows, which is the whole point when you run hot at night but the room is cold. The Kottinu knit is temperature-regulating: it wicks sweat off the skin, dries fast and keeps air moving through the sleeve. An odor-control finish helps the fabric stay fresher between washes. It is a lightweight knit cut relaxed through the body, so it layers under a robe or over a tank without bulk. In Black, Navy and Merlot, in sizes S to 3X.

Why wear long sleeves if I sleep hot?

Rooms and bodies do not always agree. A long sleeve in a fast-drying knit gives you coverage when the room is cold and keeps working if you warm up during the night.

Is this a top or a nightshirt?

It is a t-shirt style top, cut to be worn with a separate bottom. If you want a one-piece knee-length shirt, see the NightCool nightshirts.

Is it thin enough to layer?

Yes. It is a lightweight knit that layers under a robe or over a tank without bulk.

Why you'll love it

Long sleeves for full coverage without giving up cooling performance
Kottinu moisture-wicking fabric that wicks perspiration and dries quickly, engineered for night sweats and hot flashes
Soft, cotton-like feel that resists pilling and holds its shape
Bact-Out finish helps the fabric stay fresher between washes
Mix and match with any NightCool bottom for a complete long-sleeve sleep set

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

Where it is made

Every NightCool piece is made in Thailand by the same factory partner Cool-jams has trusted since day one.

size medium black jogger sets
i have been trying to get size medium black joggers for months, and they have been out of stock. i wear cool jams exclusively as a person who is disabled, but still enjoys fashionable loungewear. When can i expect to order them?
i love your cool jams.
thank you.

Love the softness of these pjs. This was my 5th set. They come in pretty colors. My only complaint is that this set is a bit smaller than the others. I like the roomier fit better.

Great fit and feel

Women's DayBasics Long Sleeve Drawstring Pant Pajama Set
I recommend this product
Rated 4 out of 5 stars

Love the fabric. Wish you'd ditch the drawstring at the waist.
Drawstring at waist is much too bulky. Please make the bottoms with the option of requesting with an elastic waist, like some I have that were purchased a long time ago. The drawstring is simply too bulky.
