Waking up too warm in the middle of the night? This soft cooling nightshirt lets air through and wicks sweat away. Great for hot flashes, night sweats, travel, beach days, or as a swimsuit cover-up. Sleep cooler, and rest easy with our 30-Night Trial.
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.
A nightshirt that does not look like one the moment you walk outside.
Wear it for
- Warm nights. Short sleeves, scoop neck, and a cut that lets air move.
- Night sweats and hot flashes. The fabric wicks and dries fast.
- The pool and the beach. It works as a swimsuit cover-up and dries quickly after.
- Holidays. One piece that covers the night and the morning after.
- Guest rooms, where you would rather not answer the door in a gown.
Why it feels good
- The scoop neck keeps your throat and chest open to the air.
- Relaxed through the body, so nothing clings when it is humid.
- Soft, cotton-like and smooth, wet or dry.
- Bact-Out keeps it fresher between washes.
- Holds its shape and resists pilling.
Good to know
- Three colours: Black, Navy and Merlot. Sizes S to 3XL.
- Machine wash cold or warm on a gentle cycle, tumble dry low or hang to dry. No bleach, and skip fabric softener and dryer sheets: they coat the microfibres and can reduce wicking.
- Made in Thailand by the same factory partner Cool-jams has worked with since the beginning.
- Sleep in it for 30 nights. Not right? Send it back for store credit or a refund.

More about the Scoop Neck Nightshirt/Cover-Up
The Cool-jams NightCool Scoop Neck Nightshirt/Cover-Up does two jobs. It is a knee-skimming cooling nightshirt for anyone who overheats at night, and it works as a beach or pool cover-up during the day. The Kottinu knit wicks moisture and dries fast, which is also why it travels well: rinse it, hang it, wear it again. An odor-control finish helps the fabric stay fresher between washes, which matters more on the road than at home. The scoop neckline and relaxed body keep it easy to wear either way. In Black, Navy and Merlot, in sizes S to 3X.
Can I wear this as a cover-up?
Yes. The knee-skimming length and the scoop neckline read as a beach cover-up in daylight, and the fabric dries quickly if it gets wet.
Is it good for hot hotel rooms?
It is one of our most popular travel pieces for that reason. The fabric breathes and dries fast, so an unfamiliar room that runs warm is easier to sleep through.
What sizes and colors does it come in?
Black, Navy and Merlot, in sizes S through 3X.
