Rib-Knit Muscle Tank Top - Black

Wash them individually or together with others if you have more than one (like I do). I bought one black and one grey, initially, and preferred to wear the black all the time. It got washed whenever a load was going into the washer and dried with whatever it was washed with. In short time it pilled up with white lint that is almost impossible to remove. So, I bought 4 more black ones and only wash them together without any other clothing. Problem solved. LOVE these shirts, BTW!!
