Using these Space Marine hoodies is easy. Just put them on and enjoy their style and comfort. When it's time to clean, machine wash them cold inside out with clothes of the same color. Only use non - chlorine bleach if needed. After washing, you can hang them to dry for the best look or use a tumble dryer on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean these hoodies to keep them in good condition.
