These 'Crest of Sincerity' hoodies are easy to use. Just put them on and enjoy the comfort. When it's time to clean, remember to machine wash them cold, turning them inside out and washing with similar colors. Only use non - chlorine bleach if necessary. For the best look, hang them to dry after washing. You can also use the tumble dryer on a cool or low - heat setting. Don't use fabric softener as it can make the colors fade. And never iron or dry clean these hoodies to keep them in good condition.
