These Olipop Infinity Tour tank tops are easy to use. Just put them on and enjoy their comfort throughout the day. For men and unisex sizes, you'll have a great fit from XS to 2XL. Women can choose from sizes XS to 4XL for a feminine look. When it's time to clean, machine wash them cold and turn them inside out. Wash with clothes of similar colors. Only use non - chlorine bleach if necessary. Hanging them to dry gives the best results, but you can also use a tumble dryer on cool or low heat. Remember, don't use fabric softener as it might make the colors fade. And never iron or dry clean these tank tops to keep them in good condition.
