To use these tank tops, simply put them on and enjoy their comfort. For men and those looking for a unisex fit, pick the size from XS to 2XL. Women can choose from sizes XS to 4XL. When it comes to cleaning, always machine wash them cold and turn them inside out. Wash with clothes of similar colors. Only use non - chlorine bleach if really needed. After washing, hanging them to dry is the best option, but you can also use a tumble dryer on cool or low heat. Be careful not to use fabric softener as it can make the colors fade. And don't try to iron or dry clean these tank tops to keep them in good condition.
