To use these tank tops, simply put them on and enjoy their comfort. For men and unisex sizes, choose from XS to 2XL, and for women, there are sizes from XS to 4XL. When it's time to clean them, machine wash them cold inside out with clothes of similar colors. If they get dirty, use non - chlorine bleach only when really needed. After washing, hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Remember, using fabric softener might make the colors fade, so it's better to skip it. Also, don't iron or dry clean these tank tops to keep them in good shape.
