Wake up cool and dry. The Cool-jams Men's NightCool Pants are men's 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 men.

More about the Pajama Pants

The Cool-jams NightCool Pants are cooling pajama pants for men who run hot at night and still want full-length coverage. The Kottinu knit wicks sweat off the skin and dries fast, so covered legs do not mean an overheated night, and an odor-control finish helps the fabric stay fresher between washes. The waistband is soft and elastic, and the leg is cut straight with room to move. It is designed to be worn with the NightCool Crew Neck T-Shirt or Tank Top, both cut from the same fabric. In Black and Navy, in sizes M to 2X.

Are full-length pants too warm if I sleep hot?

Not in a performance knit. Kottinu moves moisture and keeps air flowing, so the length adds coverage without the heat you get from cotton or flannel.

What is the men's size range?

The men's NightCool range runs M through 2X.

What tops match them?

The NightCool Crew Neck T-Shirt and the NightCool Tank Top in the men's range.

  • Kottinu moisture-wicking fabric that wicks perspiration and dries quickly, engineered for hot sleepers and night sweats
  • Soft, cotton-like feel that resists pilling and holds its shape
  • Bact-Out finish helps the fabric stay fresher between washes
  • Mix-and-match with any NightCool top

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
