This Olipop sweatshirt is easy to use. Just put it on and enjoy its comfort. When it's time to clean, remember to machine wash it cold, turning it inside out and washing with similar colors. Only use non - chlorine bleach if really needed. For the best look, hang it to dry after washing. You can also use the tumble dryer on a cool or low - heat setting. Don't use fabric softener because it can make the colors fade. And please don't iron or dry clean this sweatshirt to keep it in good condition.
