Kicking off the covers at 2 a.m.? These soft, full-length cool pajama pants pull sweat off your skin and dry quickly. Made for hot flashes, night sweats, air-conditioned bedrooms, travel, or as lightweight lounge pants. 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.

Full-length pants that stay light, for the sleepers who want to be covered and still not too warm.

Wear it for

  • Cooler nights and cold bedrooms, without giving up the fabric that handles a hot flash later.
  • Night sweats. The knit wicks and dries fast, so the pants are not damp behind the knee.
  • Working from home. They look like lounge pants, because they are.
  • Travel and shared rooms, where a gown is not enough cover.
  • Pairing. Any NightCool top, in any of five colours.

Why it feels good

  • Choose an elastic or a drawstring waist, so nothing digs in at the middle of the night.
  • Soft and cotton-like, not slippery and not clammy.
  • Cut loose through the leg, so the fabric never sticks to you.
  • Bact-Out keeps them fresher between washes.
  • They hold their shape and resist pilling.

Good to know

  • Five colours: Black, Navy, Merlot, Dusk Blue and Violet. Sizes S to 3XL.
  • Pick elastic or drawstring at checkout.
  • 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 Pants are cooling pajama pants built for hot sleepers and for nights when you run warm. These moisture-wicking pajama pants 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 Pajama Pants

The Cool-jams NightCool Pants are full-length cooling pajama pants for hot sleepers who still want their legs covered. The Kottinu knit wicks sweat off the skin and dries fast, so full-length coverage does not turn into overheating, and an odor-control finish helps the fabric stay fresher between washes. You choose the waist when you order, elastic or drawstring. They are cut straight through the leg with enough room to move, and they pair with any NightCool top since the range is sold as separates. Five colors, in sizes S to 3X.

Can I choose the waistband?

Yes. This style is sold with a choice of elastic or drawstring waist, selected when you order.

Are full-length pajama pants too hot for night sweats?

Not when the fabric moves moisture. Kottinu is a performance sleep knit that wicks and dries fast, so these stay comfortable where cotton pants would stay damp.

What tops go with them?

Any NightCool top. The range is sold as separates, so you can size the top and the bottom differently.

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
