These Teesgeex Mischief Gym hoodies are super easy to use. Just put them on and enjoy their comfort. When it comes to washing, machine wash them in cold water, turning them inside out and washing with similar colors. Only use non - chlorine bleach if really needed. After washing, you can hang them to dry for the best look, or use the cool/low heat setting in the dryer. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these hoodies, as it might damage them. Also, the zip up hoodies have a great YKK zipper, and the twill - taped neck and locker patch on both styles help keep the shape, so wear them with confidence.
