Night sweats waking you up? This soft v-neck sleep shirt pulls sweat off your skin and dries quickly. Ideal for hot flashes, menopause nights, travel, humid summer nights, or lazy mornings at home. 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.

One piece, nothing to coordinate, and a neckline that does not sit up against your throat when you are already warm.

Wear it for

  • Night sweats and hot flash nights. The knit moves sweat off your skin and dries fast, so you are not lying in a damp shirt at 3 a.m.
  • Warm bedrooms. Knee length and cut loose, so air keeps moving from the neckline down.
  • Travel and guest rooms. One piece to pack, and it is dry by morning if you rinse it out.
  • Recovery weeks and hospital bags, when pulling on pants is the last thing you want.
  • Pairing. Add NightCool capris or shorts underneath if you like a layer.

Why it feels good

  • The V opens the neckline, which is the first place most women feel heat.
  • Soft and smooth with a cotton-like feel. Nothing about it reads as gym kit.
  • The body falls away from you instead of clinging, so turning over does not drag the fabric with you.
  • A Bact-Out finish helps it stay fresher between washes.
  • It holds its shape and resists pilling wash after wash.

Good to know

  • Four colours: Black, Navy, Merlot and Violet. Sizes S to 3XL.
  • Short sleeves, knee length, cut for coverage rather than shape.
  • 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.

Wake up cool and dry. The Cool-jams Women's NightCool V-Neck Nightshirt is a cooling nightshirt built for hot sleepers and for nights when you run warm. This moisture-wicking nightshirt 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 V-Neck Nightshirt

The Cool-jams NightCool V-Neck Nightshirt is a knee-skimming cooling nightshirt with an open V neckline that leaves the throat and upper chest uncovered, which is what many women want on hot flash nights. The body is cut from temperature-regulating Kottinu fabric that wicks sweat off the skin and dries fast, and an odor-control finish helps the fabric stay fresher between washes. It is relaxed through the body with short sleeves, so nothing pulls when you turn over. In Black, Navy and Merlot, in sizes S to 3X.

Is a V-neck better for hot flashes?

An open V neckline leaves more of the throat and chest uncovered than a high or closed neck, which is why many women who sleep hot choose this style.

Is this a nightshirt or a sleep shirt?

Both names describe the same garment: a knee-length shirt worn on its own to sleep in. You will see it listed as a women's sleep shirt and as a nightshirt.

How does the fabric handle sweat?

Kottinu is a performance sleep knit. It pulls perspiration off the skin as it forms and dries fast, instead of holding it against you the way cotton does.

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

    Drying time impt to me

    Wanted these for a trip so we could hand wash our things. I soaked a shirt sleeve and it dried up pretty rapidly. Tested it. Unfortunately, I didn't time that process as I wasn't intending a review. I have learned in the past that it depends upon the air circulation in the hotel bathroom. One place we had to put our things out on a narrow balcony to get them to dry. Another place we had socks drying in sunlight on the back dash of the rental car. So, I cant tell you specifically about drying time, but I bought them to dry quickly for a trip. But, I do occasionally get sweaty at night and was in need of new nightshirts as well. So, I sized up because I prefer a looser fit, and it was a good decision.

    Thank you for such a thoughtful review, Beth! You're absolutely right that drying time depends a lot on air circulation. Your balcony and back-dash stories are a great reminder of how real travel washing actually works. We're so glad the sleeve test impressed you, and that sizing up gave you the looser fit you wanted. Wishing you a safe and wonderful trip always, and thank you for choosing Cool-jams!
