These tank tops are easy to wear right out of the package. For men and unisex, pick a size from XS to 2XL. Women can choose from XS to 4XL. When it's time to clean them, just throw them in the washing machine on a cold cycle. Make sure to turn them inside out and wash with similar colors. If they get dirty, use non - chlorine bleach only when needed. After washing, hanging them to dry is the best way. But if you're in a hurry, you can tumble dry on cool or low heat. Remember, using fabric softener can make the colors fade. And don't try to iron or dry clean them, as it might damage the fabric.
