Wake up cool and dry. The Cool-jams Women's NightCool Elastic Waist Tulip Shorts are cooling sleep shorts built for hot sleepers and for nights when you run warm. These moisture-wicking sleep shorts are 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 Elastic Waist Tulip Shorts

The Cool-jams NightCool Elastic Waist Tulip Shorts use an overlapping tulip hem, where the panels cross at the outer thigh so the leg opening is wider and moves more freely than a closed straight hem. They are a good pick for anyone who overheats at night and finds a straight-cut sleep short restrictive. The waist is elastic, and the Kottinu knit wicks sweat and dries fast, with an odor-control finish that helps the fabric stay fresher between washes. In Violet, Navy and Island, in sizes S to 3X.

What is a tulip hem?

The hem overlaps at the outer thigh like the petals of a tulip, so the leg opening is wider and moves more freely than a closed straight hem.

What top goes with these?

The NightCool Tulip Tank Top is the matching piece, and any NightCool top works since the range is designed to mix.

What sizes do they come in?

Sizes S through 3X, in Violet, Navy and Island.

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

    images misleading

    The images on the site for the tulip shorts are misleading: they have hemmed the sides for these photos. In reality, the sides are not hemmed together. The sides are open up to the waist (a full tulip hem, for sure!). So, these shorts are maximum cooling because if you are sleeping on your side, the shorts fall away exposing, well, you know what. If you are sitting, there's only a small overlap at the waistband that's together on the sides of the shorts. If that's okay, these are shorts for you.

    Thank you for taking the time to write this, Jen, and for describing the fit so clearly.

    You are right. The tulip hem is built to overlap rather than close, for airflow on hot nights, but our photos and our copy do not show how far it opens when you move or sleep on your side. Shoppers should be able to see that before they buy, so we are updating the photos and rewriting the description.

    If these are not right for you, contact our Care team and we will arrange an exchange or a return. [email protected]

    Tulip hem = maximum airflow because sides not stitched together (only overlap)

    Material is fine. Waist size is fine. It's close to a high-waisted fit. Ordered Medium. I'm hourglass body shape and wear 28" waist in jeans (5'7", 130 lb). The tulip hem creates an decent overlap of the side panels but they are not sewn together at all. The sides are sewn only at the waistband. This means rolling over or a slight gust of wind, causes the side panel to fall away and exposing the entire side leg and butt check up to the waistband. Similar effect on the front. So that's why I gave two stars: it's just not practical for me to be frequently pulling the side panel in place to cover myself. I'll try to hem it to keep the side panels together farther down the leg. It's loose fit so should work. Bottom line: if you want maximum coolness because there's no sides hemmed together, this is perfect for you. Not for me though.

    Thank you for this, Monica. Measurements and all, this is a genuinely useful review, and we would rather have it than not.

    You are right that the tulip panels overlap rather than close, which is where the airflow comes from. What our page does not make clear is how far they open when you roll over or catch a breeze. That is on us. We are rewriting the copy and updating the photos so the cut is obvious before anyone buys, not after.

    If you would rather not alter something you paid for, our Care team will take them back, no fuss.
