To use these Frey University tank tops, simply put them on and enjoy their comfort. For men and those who prefer unisex styles, pick the size from XS to 2XL. Women can choose from sizes XS to 4XL. When it's time to clean them, just toss 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 necessary. After washing, hanging them to dry is the best way to keep them in good shape, but you can also tumble dry on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these tank tops to avoid damaging them.
