To use these hoodies, simply put them on and enjoy their comfort. For zip-up hoodies, use the YKK zipper to open and close. When it's time to clean, machine wash them cold inside out with similar colors. Only use non - chlorine bleach if needed. Hang them to dry for the best look, or you can tumble dry on cool/low heat. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry clean these hoodies to keep them in good shape.
