These Olipop hoodies are super easy to use. Just put them on and you're ready to show off the cool 'Hit Me' design. When it comes to washing, remember to turn them inside out and wash them in cold water with similar colors. Only use non - chlorine bleach if needed. After washing, it's best to hang them to dry. But if you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Don't use fabric softener as it can make the colors fade. And please don't iron or dry clean these hoodies to keep them in good condition.
