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 Soft

I purchased Cool-jams pajamas (long sleeve top and long pant bottom) for my husband's birthday last month. He loves them! He said that they are great for traveling and feel better than silk.

The best men's PJs

These are the most comfortable pajamas for my husband, who has lots of problems with sensitive skin and comfort sleeping. They hold up well with frequent washing.
