How to use these tank tops is simple. Just put them on and enjoy the comfort. For men and those choosing the unisex style, pick the size from XS to 2XL. Women can select from sizes XS to 4XL. When it comes to cleaning, remember to machine wash them cold and turn them inside out. Wash with clothes of similar colors. Only use non - chlorine bleach if needed. After washing, it's best to hang them dry, but you can also tumble dry on cool or low heat. Be careful not to use fabric softener because it might make the colors fade. And don't try to iron or dry clean these tank tops.
