Using these Hypertwenty tank tops is easy. Just put them on and enjoy the comfort! For men and those looking for a unisex fit, pick from sizes XS to 2XL. Women can choose from sizes XS to 4XL. When it's time to clean them, remember to machine wash cold and turn them inside out. Wash with clothes of the same color to prevent color bleeding. Only use non - chlorine bleach if there are stains. After washing, hanging them to dry will keep them in great shape. But if you're in a hurry, you can tumble dry on cool or low heat. Stay away from fabric softener because it might make the colors fade. And don't iron or dry clean these tank tops to keep their quality intact.
