Using these Ben Swolo's Gym hoodies is as easy as just putting them on. You can choose between the zip - up style for easy on - and - off or the pullover style for a more classic look. When it's time to clean them, remember to machine wash in cold water and turn them inside out. Wash them with similar colors to prevent color bleeding. Only use non - chlorine bleach if you really need to whiten them. After washing, it's best to hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. Stay away from fabric softener because it can make the colors fade. And don't try to iron or dry clean these hoodies as it might damage the material. Keep these tips in mind, and your hoodies will last you a long time.
