We started you on the Scoop T-Shirt and the Capri Pants, our two best sellers.
Cool-jams NightCool is made from Kottinu, our proprietary performance polyester microfiber. Like our everyday DayBasics microfabric, it is soft, lightweight, and breathable with a cotton-like feel. The difference is what happens when you sweat: Kottinu is engineered as a performance sleep fabric for people who sleep hot.
Kottinu uses our Moisture Transference System (MST), a three-step process built into the fabric. Ultra-fine microfibers pull sweat off your skin as it forms, spread it across the surface of the fabric, and let it evaporate quickly. As moisture evaporates it carries body heat with it, helping you stay dry and comfortable.
NightCool fabric is finished with Bact-Out, a treatment that helps the fabric itself resist odor so your sleepwear stays fresher between washes.
Kottinu keeps the soft, cotton-like feel you want from sleepwear without holding onto moisture the way cotton does. It resists pilling, holds its shape, machine washes easily, and dries quickly.
Every NightCool piece is made by our original manufacturer, who we have trusted from day one to make the technical fabric that keeps you dry and cool.

The Cool-jams NightCool Scoop T-Shirt is a short sleeve cooling sleep tee for women who sleep hot. The scoop neckline leaves the throat open and the Kottinu knit wicks perspiration off the skin and dries fast, with an odor-control finish that helps the fabric stay fresher between washes. It is cut relaxed through the body so it does not cling, and it is finished like a normal tee, which is why customers wear it for travel as well as sleep. Five colors, in sizes S to 3X.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.
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.
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.
Relaxed. The shoulder and sleeve sit close, and the body falls away from the pleat.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.
The Cool-jams NightCool V-Neck Top is a short sleeve cooling pajama top built around an open V neckline that leaves the throat and upper chest uncovered, which is what many women want on hot flash nights. The Kottinu knit wicks perspiration as it forms and dries fast, and an odor-control finish helps the fabric stay fresher between washes. The body is cut relaxed so it keeps fabric off the skin. Designed to mix with any NightCool bottom, in Black, Navy and Merlot, in sizes S to 3X.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.
The Cool-jams NightCool Long Sleeve T-Shirt covers the arms without the heat that usually follows, which is the whole point when you run hot at night but the room is cold. The Kottinu knit is temperature-regulating: it wicks sweat off the skin, dries fast and keeps air moving through the sleeve. An odor-control finish helps the fabric stay fresher between washes. It is a lightweight knit cut relaxed through the body, so it layers under a robe or over a tank without bulk. In Black, Navy and Merlot, in sizes S to 3X.
Rooms and bodies do not always agree. A long sleeve in a fast-drying knit gives you coverage when the room is cold and keeps working if you warm up during the night.
It is a t-shirt style top, cut to be worn with a separate bottom. If you want a one-piece knee-length shirt, see the NightCool nightshirts.
Yes. It is a lightweight knit that layers under a robe or over a tank without bulk.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.
The Cool-jams NightCool Scoop Neck T-Shirt with 3/4 Sleeves is made for warm sleepers and warm nights that do not stay one temperature. The three-quarter sleeve covers the upper arm and stops clear of the wrist, so you are not pushing fabric up all night, and the scoop neck keeps the chest open. Kottinu fabric wicks sweat and dries fast, and an odor-control finish helps the fabric stay fresher between washes. Designed to mix with any NightCool bottom, in Black, Navy and Merlot, in sizes S to 3X.
It ends between the elbow and the wrist, covering the upper arm while leaving the forearm free.
Slightly, because of the extra sleeve, but the fabric is identical and still wicks and dries fast.
Yes, the solid colors are shared across the NightCool range so tops and bottoms can be mixed.
Wake up cool and dry. The Cool-jams Women's NightCool Tulip Tank Top is a cooling tank top built for hot sleepers and for nights when you run warm. This moisture-wicking tank top 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.
The Cool-jams NightCool Tulip Tank Top is a cooling tank top for women who sleep hot, finished with an overlapping tulip hem that falls softly over the hip rather than cutting straight across it. It is sleeveless with a scoop neckline, so there is very little fabric holding heat, and the Kottinu knit wicks sweat and dries fast. An odor-control finish helps the fabric stay fresher between washes. Wear it to sleep or to lounge, in Violet, Navy and Island, in sizes S to 3X.
For most hot sleepers it is the coolest top we make, because it leaves the arms and shoulders bare and uses the least fabric.
The tulip hem falls over the top of the hip and covers the waistband of matching NightCool bottoms.
Yes, the tulip hem and scoop neck read as a regular tank, so it works for lounging as well as sleep.

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.
The Cool-jams NightCool Capri Pants are cropped cooling pajama pants made for night sweats and hot flashes. The mid-calf length leaves the lower leg free, which is where a lot of heat escapes, while still covering more than shorts. You choose the waist when you order, elastic or drawstring, so the fit suits you rather than the pattern. The moisture wicking Kottinu fabric pulls sweat off the skin and dries fast, and an odor-control finish helps the fabric stay fresher between washes. Five colors, in sizes S to 3X.
Yes. This style is sold with a choice of elastic or drawstring waist, selected when you order.
Leaving the lower leg uncovered vents heat, so capris suit people who want more than shorts but find full-length pants too warm.
Yes. The NightCool bottoms and tops are sold separately and made to be mixed, so you can size each piece independently.

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.
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.
Yes. This style is sold with a choice of elastic or drawstring waist, selected when you order.
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.
Any NightCool top. The range is sold as separates, so you can size the top and the bottom differently.
Wake up cool and dry. The Cool-jams Women's NightCool 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.
The Cool-jams NightCool Shorts are cooling pajama shorts made for night sweats, and one of the lightest bottoms in the NightCool range, which makes them a usual choice for the warmest nights. You choose the waist when you order, elastic or drawstring. The Kottinu knit wicks sweat off the skin and dries fast, and an odor-control finish helps the fabric stay fresher between washes. Pair them with a NightCool tank or tee for the lightest full set. In Black, Navy and Merlot, in sizes S to 3X.
Yes. This style is sold with a choice of elastic or drawstring waist, selected when you order.
They put very little fabric on your legs. Pair them with a NightCool tank for one of the lightest full sets we make.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.
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.
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.
The NightCool Tulip Tank Top is the matching piece, and any NightCool top works since the range is designed to mix.
Sizes S through 3X, in Violet, Navy and Island.
Wake up cool and dry. The Cool-jams Women's NightCool Elastic Waist Cuff Jogger Pants are cooling pajama pants built for hot sleepers and for nights when you run warm.

Part of the Cool-jams NightCool collection of cooling sleepwear for women.
The Cool-jams NightCool Elastic Waist Cuff Jogger Pants take the jogger shape into sleepwear: a covered elastic waist, a relaxed leg and a cuffed ankle so the hem stays where you put it. That cuff is what people like when they run hot at night, because the leg can be pushed up and stays up. The Kottinu knit wicks sweat and dries fast, and an odor-control finish helps the fabric stay fresher between washes. Five colors, in sizes S to 3X.
Not usually, and many people find them cooler in practice because you can push the cuff up your calf and it stays there instead of falling back down.
It is a soft cuff with give. It holds the hem without gripping.
Yes, the jogger shape is the most street-ready cut in the NightCool range and works for lounging at home.
Wake up cool and dry. The Cool-jams Women's NightCool Drawstring Waist Wide Leg 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.
The Cool-jams NightCool Drawstring Waist Wide Leg Pants are cut generously through the leg, which is the point: a wide leg moves air with you instead of sitting against the skin, so they suit women who sleep hot. The drawstring waist lets you set the fit exactly. The Kottinu knit wicks sweat and dries fast, and an odor-control finish helps the fabric stay fresher between washes. This style comes in combined sizes, S-M, L-XL and 2X-3X, in Violet and Black.
This style comes in S-M, L-XL and 2X-3X rather than single sizes. The drawstring waist and the wide leg give the range within each size, so you adjust rather than sizing exactly.
Air moves through a wide leg as you move, which helps if you overheat. It also means nothing grips the calf or thigh when you turn over.
Many customers wear them as lounge pants. The drawstring waist and clean drape read as loungewear rather than obvious pajamas.
Wake up cool and dry. The Cool-jams Men's NightCool Crew Neck T-Shirt is a men's cooling sleep shirt built for hot sleepers and for nights when you run warm. This men's 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 men.
The Cool-jams NightCool Crew Neck T-Shirt is a cooling sleep t-shirt for men with night sweats. The Kottinu knit pulls perspiration off the skin as it forms and dries fast, so the shirt does not stay wet against your back, and an odor-control finish helps the fabric stay fresher between washes. It is cut as a standard crew neck tee, relaxed through the body and shoulder, which is why customers wear it for travel and the gym as well as for sleep. In Navy and Black, in sizes M to 2X.
Yes. It is cut like a normal crew neck tee, and the fabric performs the same way in a gym or on a plane as it does in bed.
That is what it was built for. Kottinu wicks moisture off the skin and dries fast, which is the property that matters when you sweat in your sleep.
The NightCool Pants and the NightCool Boxer Shorts in the men's range.

The Cool-jams NightCool Tank Top is a sleeveless cooling sleep tank for men who run hot at night. It is the lightest top in the men's NightCool range, leaving the arms and shoulders bare, and the Kottinu knit wicks sweat off the skin and dries fast. An odor-control finish helps the fabric stay fresher between washes. It is cut relaxed through the body with a standard tank armhole, so it is easy to sleep in and easy to layer. In Navy and Black, in sizes M to 2X.
It is the lightest top we make for men, because it removes the sleeves entirely. Pair it with NightCool Boxer Shorts for the coolest combination.
It is a standard tank armhole, not a dropped or cut-away athletic armhole.
The NightCool Pants and the NightCool Boxer Shorts in the men's range.
Wake up cool and dry. The Cool-jams Men's NightCool Boxer Shorts are men's cooling boxer shorts built for hot sleepers and for nights when you run warm.

Part of the Cool-jams NightCool collection of cooling sleepwear for men.
The Cool-jams NightCool Boxer Shorts are cooling sleep boxers for men with night sweats. The Kottinu knit wicks perspiration off the skin as it forms and dries fast, which is the difference between waking up damp and waking up comfortable, and an odor-control finish helps the fabric stay fresher between washes. The waistband is soft and elastic, the leg is cut roomy, and there is no bunching at the thigh when you turn over. In Navy and Black, in sizes M to 2X.
They are cut as sleep boxers, designed to be worn on their own in bed. The roomier leg and soft waistband are built for sleeping rather than for wearing under trousers.
Yes, and it is common. These are cut from the same Kottinu performance fabric as our women's night sweat range.
The NightCool Crew Neck T-Shirt and the NightCool Tank Top are the matching pieces in the men's range.

Part of the Cool-jams NightCool collection of cooling sleepwear for men.
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.
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.
The men's NightCool range runs M through 2X.
