Knix Super Leak Proof Bikini

Leak proof and super absorbent, these “period panties” can hold up to 8 teaspoons — or the equivalent of about  8 tampons of liquid. They’re machine washable and have been tested to ensure that they’re PFAS-free. Depending on your comfort level and the intensity of your menstrual flow, you can wear them on their own — or with the added protection of a tampon or menstrual cup.
