Thinx are washable, reusable period underwear. They look and feel just like normal underwear. These cheeky cut panties are chic, comfortable and make your butt look divine. Featuring a three-layer gusset that keeps you fresh and dry, this is Thinx’s lightest absorbency period underwear, as it can hold up to one regular tampon’s worth. Simply toss them in the wash and line dry after use.
