How to use: Just put on these tank tops and you're ready for your running activities. They are suitable for both men and women depending on the style you choose. For men and unisex, pick the size from XS to 2XL. Women can select from XS to 4XL. Care tips: When it's time to clean, throw them in the washing machine on a cold cycle. Make sure to turn them inside out and wash with similar colors. Only use non - chlorine bleach if needed. To keep them in the best shape, hang them to dry after washing. If you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Things to avoid: Don't use fabric softener because it might make the colors fade. Also, don't iron or dry clean these tank tops.
