I love this fabric and you will too. It is a very soft, four-way stretch material. It feels like your favorite cotton t-shirt with the benefits of technology. It does not crease, fade or shrink easily like cotton tends to. Don't worry - it does not retain those unpleasant odors that hang around in some synthetic athletic fabrics.
Machine wash cold or hand wash in lukewarm water.
Use mild powered detergents.
Tumble dry at low temperatures.
Do not use bleach or fabric softener.
Do not spot clean with solvents.
Do not dry clean (yay!).
