To use these XENOS DJ Groot tank tops, simply put them on and enjoy their comfort. For men and those who prefer unisex styles, choose from sizes XS to 2XL. Women can pick from sizes XS to 4XL. When it comes to washing, always use cold water and turn the tank tops inside out. Wash them with similar colors. Only use non - chlorine bleach if needed. After washing, hanging them to dry is the best option. You can also use a tumble dryer on cool or low heat. Just remember, fabric softener might make the colors fade, so avoid it. And never iron or dry clean these tank tops to keep them in good condition.
