Style #T2158 For warm evenings, this Women's Cooling Tank Top is the perfect addition to your sleepwear set. This sleeveless tank top is made using our proprietary smart fabric technology that is designed especially to wick away the moisture produced during night sweats, as well as eliminate the bacteria that causes body odor. Best of all, this technology is woven into the fabric and will never wash out no matter how many times you wear it.

While this shirt is scientifically designed to wick away moisture, it also has a soft, lightweight feel that is just as comfortable as traditional cotton. Its sleeveless design is ideal for warm weather, or match it with our pj topper and long pant bottoms to create a versatile 3-piece set. Because the Cool-jams™ fabric is also incredibly wrinkle-resistant, this is a great sleepwear piece to take with you while traveling.

  • Cool-jams™ wicking technology - absorbs moisture, keeps skin cool and comfortable all night long and eliminates body odor-causing bacteria
  • Sleeveless tank top
  • Scoop neck
  • Smooth, silky cotton-like feel
  • Dries 4X faster than cotton
  • Lightweight, wrinkle-resistant, quick-drying material
  • Attractive color options
  • Sizes S-XXL available 
  • Garment weight approximately 3 oz.

    Care instructions


    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.

    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.

    Comfortable and well-made

    This tank is very well made, not some mass market one-season-and-done item. Helps keep me cool & dry while I sleep, and is very comfy for lounging around the house. Will definitely buy again!

    Love on first night

    I’ve been looking for this type of sleeping tank and I finally found it with Cool-Jams.

    Does keep me cooler than my other pajamas!

    I wore the cool jams tank to bed and then wore my other tanks. I definitely was more comfortable and cooler in the Cool Jams tank!

    The opposite of cooling for me

    These did not work for me at all. They fit fine and seemed reasonably well made. But the fabric made me more sweaty and overheated than ever! Admittedly I am menopausal and suffering from hot flashes (hence my reason for buying these). But I found these worse than cotton as far as making me hot and sticky.


    Thanks for your comments. We suspect you might have used fabric softener which can diminish the wicking feature of the fabric. If so, please rewash in clear water to bring back the wicking ability. Cool-jams will keep you a few degrees cooler but the primary benefit is the moisture wicking and quick drying which helps to diminish the temperature regulation issues associated with night sweats. We also advise using minimal covers and increasing air flow in your room which also helps the fabric to work it's magic.
