How to use this sweatshirt? Just put it on and enjoy its comfort. When it gets dirty, machine wash it cold, turn it inside out and wash with clothes of similar colors. Only use non - chlorine bleach if there are stains. After washing, it's best to hang it to dry. You can also use the tumble dryer on cool or low heat. Be careful not to use fabric softener because it might make the colors fade. And don't iron or dry clean it to keep it in good condition.
