Women who are menstruating have options. Period panties, like these created by Thinx, are absorbent and moisture-wicking. They're reusable and replace panty liners or tampons for some women on some days of their cycle.
Disposable pads with an adhesive back are a popular option for women who are menstruating.
Reusable cloth pads are typically held in place by a snap and can be washed between uses.
About 70% of all American women use tampons, which are typically made of cotton, rayon and other fibers and are inserted into the vagina. Many can be worn for up to eight hours.
