To use these tank tops, simply put them on and enjoy the comfort. For men and unisex ones, pick your size from XS to 2XL, and for women, choose from XS to 4XL. When it comes to washing, set your machine to cold and turn the tops inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if stains appear. After washing, it's best to hang them to dry. If you're in a hurry, you can use the cool or low - heat setting on your dryer. Remember, fabric softener can make the colors fade, so skip it. Also, don't try to iron or dry - clean these tops as it may damage the material.
