To use these tank tops, simply put them on and enjoy the comfortable fit. For men and those choosing the unisex style, pick your size from XS to 2XL. Women can choose from sizes XS to 4XL. When it's time to clean, remember to machine wash in cold water. Turn the tops inside out and wash with similar colors. Only use non - chlorine bleach if needed. After washing, hanging them to dry is the best option, but you can also tumble dry on cool or low heat. Don't use fabric softener as it might make the colors fade. And please don't iron or dry clean these tank tops to keep them in good condition.
