Style #T4395 Create your own set of moisture-wicking sleepwear with these Men's Cooling Boxers from Cool-jams™. With side seam pockets, a shorter hemline and relaxed elastic waistband, these sweat wicking boxers are just as comfortable as they are functional. To wick away moisture caused by night sweats, our unique Cool-jams™ technology is woven throughout their soft, silky fabric. This innovative technology will never wash out, no matter how often you wear them, and it even helps to eliminate the bacteria that causes odor on the skin. Because it helps to regulate your body temperature from cool to warm and back again, you can wear these men's wicking boxers all year round.

Choose a pair of cooling boxers from a variety of stylish colors, and even pair them with one of our other wicking separates on top. Because of the men's wicking boxers' lightweight feel and wrinkle-resistant properties, these boxers are also a great option for travel. Inseam length 5.5".

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.

Perfectly cool night

I live in Arizona and it's the hot summer. These PJs are perfect - fit as advertised, moisture wicking, and look good, too. Thanks so much. My wife wears them and she's the one who convinced me to give 'em a try. She loves hers.

My husband loves them!

I decided to “replace” my husband’s old sleeping shorts. He LOVES them & wants me to order another pair!

Possible change in material???

good put did not seem to be the same material as the 1st pair I purchased a year ago.


We definitely have not changed our fabric formula; however our sleepwear does get softer and softer with repeated washing. I'm guessing that is the perceived difference. The older items might appear to be softer, but rest assured, the new items will feel the same soon:)!!
