    Great PJ’s

    Hot flashes were much more manageable with these PJ’s. It seemed like as soon as I could feel it coming on, it was gone. I never had to practically strip out of them while I sweated it out.

    Great products!

    These pajamas are very well made with soft fabric that does help keep me cool, especially in the recent heat wave in my area. It went through the first wash without any shrinkage or wrinkling.

    The fit is great, roomy but not too big. The fabric is see thru and not as soft as I expected. After the third wash they have gotten softer though.

  • What Are Cool-jams?

     Are you looking for a way to battle those night sweats or a great pair of quick drying travel pajamas? Or perhaps it's menopause or nursing pajamas that you need? Our Cool-jams fabric is a specially designed polyester Microfiber that has been engineered to feel like soft cotton but has all the attributes associated with the fastest wicking and drying material in the world. This ground-breaking Cool-jams technology, with its super soft "cotton-like" comfort and feel, offers the superior odor and bacterial control of our natural antibacterial treatment and delivers unparalleled performance in moisture management, lasts 6 times longer than cotton fabric, maintains color with minimal fading. 

    How Were Cool-jams Developed?

    Our Cool-jams fabric was developed initially for the Canadian armed forces. The military had requested development of a fabric that would look and feel like cotton but had other characteristics to include wicking ability, temperature regulation, quick drying ability, Anti Microbial longevity and effectiveness, Anti-pilling, washability, breathability and wearability. Our proprietary technology was later engineered into our super-soft Cool-jams sleepwear which makes Cool-jams the most innovative and advanced performance sleepwear collection available anywhere. Our customers tell us that once they've tried Cool-jams Wicking Performance Sleepwear, they will never sleep in anything else again.

    Now let's get down to the science behind our Cool-jams products:

    Moisture Transference System (MST)

    MST microfiber technology uses very fine fibers which are made into long strand fibers called filaments. Each filament is less than 1 decitex in measure, finer than a strand of human hair. Five to 8 filaments, each filament having slightly different performance capabilities, are twisted together to form a fine thread. Due to the unique blend of filaments, and their configuration within the thread, this creates a greater surface area for moisture to travel along the thread. These threads are then knitted together in a specific pattern which increases the speed of moisture movement through the material.

    MST is a three step process: 

    1. as the body perspires, moisture is transferred through the material from the skin to the outer layer of clothing, a process called moisture absorption or wicking; 
    2. the moisture spreads over the surface area (moisture transport or disbursement); 
    3. the disbursement process allows the outer air to evaporate the moisture (moisture drying or evaporation).

    As moisture is pulled away from the body it carries with it the body’s built up heat, helping to regulate body temperature. This is an invaluable process as it also minimizes excessive temperature swings in the body during sleep. MST technology provides body heat regulating while minimizing energy expended to keep the body cool and comfortable.

    Cool-jams fabrics disperse moisture over larger areas in record time for faster drying and optimal wearer comfort. In lab testing, there is no other sleepwear that comes close to this performance!


    Capillary action is the movement of moisture (liquid along the surface of a the fabric (solid) caused by the attraction of moisture molecules into the fabric molecules. Maximizing the capillary action of the fabric increases its ability to absorb moisture off the body to its outer surface. Cool-jams fabrics disperse moisture over larger areas in record time. Once on the surface of the fabric the vaporization of moisture molecules begins.

    MST technology can be constructed to suit the performance characteristics for the conditions of use. Fabrics can be constructed to reduce or accelerate air flow (e.g. in cooler conditions where tighter weaves and increased density allows for warmth to be captured and retained while allowing for moisture disbursement).

    Antimicrobial Technology

    Cool-jams® proprietary antimicrobial technology enables superior odor and fiber degradation resistance in our fabrics through the use of a powerful yet natural antimicrobial agent. The Cool-jams® antibacterial treatment is integrated into the fabric in a manner which allows for complete protection of the fabric and has been proven to be consistently effective with no tendency to cause discoloration. It is environmentally friendly and EPA approved.

    The superior performance of this new generation antimicrobial technology has been achieved by combining application expertise with proprietary nano-technology manufacturing processes. The ultra-fine particles adhere more effectively to the fabric for longer protection and is 100% environmentally friendly.

    Laboratory results confirm that the antimicrobial properties of our proprietary antibacterial agent remain strong after 50 or more machine washes – a powerful benefit for consumers of sports and leisurewear. In trials, using typical application processes on Cool-jams fabrics, the bacterial kill rate after 50 machine washes was 99.9%.

    With Cool-jams® technology your Cool-jams Sleepwear will always stay fresh and odor free.

  • What's Different About Cool-jams?

    At Cool-jams we believe that cool is not just a vibe or way of being hip, but rather a better way to sleep. Finding comfortable pajamas remains a major challenge for many. Fortunately, there's Cool-jams, high-performance pajamas that are lightweight, wrinkle-resistant and constructed to last. We have worked hard to create a super soft collection of products without uncomfortable seams, itchy lace or inside labels. You'll find that Cool-jams are some of the coolest, softest and most functional sleepwear that you'll find anywhere.

    Cool-jams™ was recently selected as one of the most innovative apparel companies in the US. Let us explain more about why Cool-jams received this honor and why we have sold more wicking pajamas around the world than any other wicking pajama brand.

    • Super Soft and comfortable: No itchy labels, lace or uncomfortable inner seams. Our product development team has worked hard to bring you a collection of hard-working functional, yet stylish collection of comfortable sleepwear.
    • Wicks heat and moisture and dries faster than regular cotton, terry, poly/cotton, and any other wicking brands tested: Side-by-side testing shows that Cool-jams sleepwear absorbs moisture, wicks heat and moisture and dries faster than cotton, poly/cotton or any other wicking performance fabrics tested. Cool-jams provide an incredibly effective way to deal with night sweats, hot flashes or other temperature regulation problems. Don't settle for an inferior wicking products when you can sleep in Cool-jams Sleepwear.
    • Top-performing travel pajamas: Cool-jams™ are lightweight, quick drying, compact and wrinkle-resistant, making them awesome travel pajamas for cold or warm weather. You can rinse them out in the sink and hang them up to dry in the morning, and they'll be ready to wear when you need them that evening.
    • Regulate body temperature more effectively than regular cotton: Regular cotton fabric (loop terry, velour, woven or knit) absorbs moisture but dries very slowly, thus trapping the moisture next to your skin. Our innovative moisture-wicking smart fabric absorbs both heat and moisture quicker than regular cotton, draws the moisture away from the skin and evaporates quickly, keeping your body temperature controlled all night. When you're hot, the fabric keeps you cool. And when you're cold, the fabric will keep your body temperature just right. With Cool-jams, you'll never feel too hot or too cold, always just right!
    • Quick drying: Cool-jams sleepwear dries four times faster than polyester, terry, velour or regular cotton pajamas and twice as fast as other leading wicking pajama brands.
    • Feel like cotton: Our micro-fiber moisture-wicking smart fabric is unlike any other wicking pajama in the marketplace. Cool-jams are super soft with a silky cotton-like feel, even though the fabric is 100% micro-fiber. Many wicking fabrics have a sticky polyester hand feel, but not Cool-jams™. In fact, many of our customers tell us that Cool-jams are the most comfortable pajamas they have ever worn.
    • Lightweight: Our comfortable pajamas are made of the lightest and coolest micro-fiber you will find anywhere. They never feel thick and heavy like some sleepwear fabrics. The average weight of our pajamas is only 6-14 oz. (depending on the style/size).
    • Unsurpassed quality control: Cool-jams has complete control over all aspects of our comfortable sleepwear production from weaving our fabric to stitching our pajamas. What better quality assurance could you have? Every Cool-jams garment is produced with quality in mind and passes multiple inspections and testing before it arrives at our warehouse.

    Cool-jams' award winning sleepwear is great for travel because its  lightweight, compact, wrinkle resistant and quick drying. In fact you won't find a more comfortable travel pajama anywhere. Once you try Cool-jams we know you won't leave home without them. 

    All of our Cool-jams wicking pajamas and nightgowns are manufactured using our exclusive moisture wicking  polymicrofiber smart fabric with incredible wicking and quick-dry properties. The fiber content is 100% polymicrofiber with the exception of our midnight color which contains 35% rayon to give it the melange look.  The hand-feel and amount of stretch is like a super soft cotton t-shirt material. The poly microfiber yarn we use in our fabric has advanced evaporation and thermo-regulation properties, which helps to reduce the body's temperature to ensure a great night’s sleep. In fact, testing shows that our Cool-jams fabric wicks and dries 4 times faster than cotton or poly/cotton. We've also tested every leading wicking sleepwear brand and found that there is no other brand with a more effective moisture wicking fabric than Cool-jams. Unlike other wicking fabrics, the wicking ability of Cool-jams is scientifically woven into the fabric, so the wick never washes out. This feature translates to a cool comfortable sleep regardless of how warm you get. Learn more about the science behind our Cool-jams Sleep Technology.

    Regular cotton fabrics are relatively absorbent, but keep the moisture next to the skin because cotton dries slowly keeping you wet and uncomfortable. Polyester fabrics are not absorbent, thus keeping you hot and sticky. Cool-jams Sleepwear is made of 100% poly microfiber with superior wicking properties to absorb heat and moisture faster than cotton or polyester. Additionally, the fabric draws the moisture and heat away from the skin and then dries very quickly. In fact it dries 4 times faster than regular woven or knit cotton fabrics. Customers and experts alike tell us that Cool-jams are a great solution for women suffering from menopause hot flashes, for those living in warm climates, or for anyone just trying to stay cooler at night. *Note our midnight color has 35% rayon to achieve the variegated color effect.

    To enhance the moisture wicking and quick dry features of your Cool-jams sleepwear, we recommend  having air flow in your room (fan or open window) and minimal or light bed covers. 

    The drying time for Cool-jams Sleepwear depends on several factors: room temperature, room humidity and the amount of moisture left in the fabric after washing. If you are hand washing, we recommend hand wringing first and then wringing inside a twisted towel for a faster drying time. Depending on all of the above factors, dry time can be 5 minutes (tumble dry) to 4 hours (hanging). Sorry that we cannot be more specific, but we can tell you that based on side-by-side testing, Cool-jams is the fastest drying microfiber sleepwear currently available in the marketplace. This quick drying feature is one of the many reasons so many customers purchase our sleepwear for travel and temperature regulation.

    It is not a problem to put Cool-jams in the dryer as long as you do not use fabric softener or softener sheets which diminish the fabric's wicking ability. Also some customers in dry climates notice a bit of static when Cool-jams are placed in the dryer.  The dry time in an automatic dryer is 5 minutes or less.  

    The softness comes from a very thin micro-fiber yarn with four times the filaments of other yarns. When we manufacture our fabric we use hundreds of strands of this unique, breathable yarn which gives Cool-jams its silky, soft, cotton like hand-feel.

    Care for Wicking Sleepwear:
    Wash in cool or warm water on gentle cycle. Never use fabric softener or fabric softener sheets because it will minimize the wicking properties of the fabric. If you accidentally use fabric softeners, re-wash the garment in clear water to remove softener residue, so the wicking properties will return to maximum effectiveness. Hang to dry or tumble dry on low. Tumble drying won't damage the garment, but can sometimes create static. If you live in a dry climate or have problems with static in your Cool-jams products, read our blog post regarding natural ways to get rid of static cling

    Although Cool-jams has built-in odor protection, after repeated use, wicking fabrics can sometimes develop a bit of an odor. If this should happen to your Cool-jams, we recommend soaking in Oxy Clean or baking soda and water solution for 15 minutes before washing. We also have found a few detergents that are helpful for odor elimination without damaging the fabric's wicking ability. Some of our recommendations include: Kirkland Ultra Clean with patented odor release technology, Arm and Hammer Liquid detergent with Oxyclean and Tide Pods plus Febreze.

    Care for Bedding Products:

    Laundering: Machine wash warm or cold, gentle cycle. Use a mild laundry detergent, and avoid liquid chlorine bleach (LCB), fabric softener, dryer sheets, and washer or dryer balls since these products will diminish the wicking ability of the fabric. If you use chlorine-free bleach, be careful to not pour it directly onto your bedding. You must pre-dilute it before adding to wash. Tumble Dry on low or medium heat and remove promptly from dryer to prevent excessive wrinkling. 

    Stains: for body or facial oils, you can pre-wash or soak the sheets with ¼ cup of Dawn dishwashing liquid, as Dawn is a natural degreaser, then launder as usual.  As soon as you see an oil stain, pre-treat so that the stain is not ‘set’ in the dryer.  For all other stains, you can Spray Oxy Clean, use non chlorine bleach, or Grandma’s Miracle Spot Remover directly onto the stain, then launder as usual.   Or a mix of 1-part white vinegar to 4-parts water, spray or pour directly onto the stain, then launder as usual.

    Bamboo Products:  Wash the bamboo bedding before using to allow for the shrinkage that happens during the first washing of bamboo. We’ve over-sized the linens to allow for that shrinkage, so if you don’t wash first; you’ll think they’re too big. Note: Bamboo comes out of the washer feeling stiff and canvas-like, that’s normal so don't worry that you've harmed your linens.
