How to use these tank tops is quite simple. Just put them on and enjoy the comfort! For men and those who prefer unisex styles, pick the size from XS to 2XL. Women can choose from XS to 4XL. When it comes to maintenance, make sure to machine wash them cold, turning them inside out and washing with similar colors. Only use non - chlorine bleach if needed. Hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Be careful not to use fabric softener as it might make the colors fade. And remember, don't iron or dry clean these tank tops to keep them in good condition.
