Waking up too warm in the middle of the night? This soft pleated pajama top pulls sweat off your skin and dries quickly. Designed for hot flashes, night sweats, travel, warm summer nights, or as a lightweight lounge top. 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.

You know the feeling. You're tucked in, and somehow you're still too warm. This is the tee we made for that.

Wear it for

  • Hot flash nights and 3 a.m. wake-ups. The knit pulls sweat off your skin and dries fast, so you settle back down instead of lying there damp.
  • Warm bedrooms and summer heat, the nights when a fan alone is not enough.
  • Travel. It packs flat and dries fast, which is handy when you are living out of a suitcase.
  • Mornings at home. It reads as a regular tee, so coffee on the porch does not need a change of clothes.
  • Building a set. Pair it with NightCool capris, shorts or pants in the same fabric.

Why it feels good

  • The soft pleat gives the fabric somewhere to fall, so it skims your stomach instead of sitting against it.
  • Soft and smooth with a cotton-like feel. People expect gym-shirt texture from a performance fabric and are surprised by this one.
  • The shoulder and sleeve sit close while the body falls away, so nothing clings when you turn over.
  • An odor-control finish helps the fabric stay fresher between washes.
  • It holds its shape and resists pilling wash after wash, which is why so many women own it in more than one colour.

Good to know

  • Five colours: Black, Navy, Merlot, Dusk Blue and Violet. Sizes S to 3XL.
  • Machine wash cold or warm on a gentle cycle, tumble dry low or hang to dry. Skip fabric softener and dryer sheets, they coat the fibres and can reduce wicking.
  • Made in Thailand by the same factory partner Cool-jams has trusted since day one.
  • 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 Pleated 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 Pleated T-Shirt

The Cool-jams NightCool Pleated T-Shirt is a short sleeve cooling pajama top made for night sweats and hot flashes, with a soft pleat at the front that gives the fabric somewhere to fall so it skims the stomach rather than sitting against it. The Kottinu knit wicks sweat off the skin and dries fast, and an odor-control finish helps the fabric stay fresher between washes. The shoulder and sleeve sit close while the body falls away from the pleat. Five colors, in sizes S to 3X.

What does the pleat do?

It releases fabric across the front so the top drapes away from the body. People who dislike a close-fitting tee usually prefer this cut.

Is this top loose or fitted?

Relaxed. The shoulder and sleeve sit close, and the body falls away from the pleat.

Is it good for night sweats?

Yes, it is cut from the same Kottinu fabric as the whole NightCool line, which wicks moisture and dries fast.

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
