These Arinesart Waker Classic hoodies are super easy to use. Just put them on and enjoy the comfort. When it comes to washing, make sure to use cold water and turn the hoodie inside out. Wash it with clothes of similar colors. Only use non - chlorine bleach if really needed. After washing, hanging them to dry is the best option, but you can also use the tumble dryer on a cool or low - heat setting. Don't use fabric softener as it can fade the colors. And remember, don't iron or dry clean these hoodies to keep them in good shape.
