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.

Cool-jams pjs

Bought for my son he loves them.. doesn't want to take them off.

Good-looking and comfy

The pj shorts arrived quickly and are great fitting. Being somewhat between sizes in pajama pants I wondered whether to get an XL or XXL and happily these run true to size, maybe a little towards the larger and the XL fits fine. The slightly longer pajama shorts look good on. They are light, stay smooth and unwrinkled. They are the most comfortable sleep shorts I've worn and are perfect for traveling because they wash out and dry so fast.

Cool jams

I like the feel of material. How they keep you warm or cool. They wash up really nice too. Just wished they weren't so expensive
