T4960 - Meet the long, sleeveless Cool-jams™ racerback nightgown for women—your ultimate ally against hot, sticky nights. Engineered from exclusive poly-microfiber smart fabric, it mimics the touch of cotton while pulling sweat away four times faster than traditional sleepwear. The result? A cool, dry feeling that sets this cooling dress apart from ordinary women’s nightgowns.
An integrated shelf bra provides light, no-clasp support, perfect for lounging or sleeping without bulky undergarments. The scoop neckline flows into a sporty racerback, keeping straps secure as you stretch, read, or flip pillows searching for the cool side.

Because the fabric resists wrinkles and dries quickly, this nightgown rolls into any carry-on and emerges fresh at your destination. Odor-control fibers mean you’ll wake up feeling as clean as you did at lights-out, whether you’re navigating humid summers, hormonal hot flashes, or beach-resort evenings.

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 (remove before completely dry). 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.

Why are Cool-jams PJs great for travel?
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.
What kind of fabric do we use for our sleepwear?
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 more comfortable temperature regulated sleep. Learn more about the science behind our Cool-jams Sleep Technology.
Why is Cool-jams sleepwear fabric better than other fabrics?
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 more temperature regulated 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. Also never use fabric softener since it diminishes the effectiveness of our fabric.
How long is the dry time for Cool-jams?
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.
Why is our sleepwear fabric so soft?
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.
