Copying my comment on another thread that seems to have fizzled out, please can someone explain his period swim suits work?
I'm picturing a built in absorption pad - like period knickers have. But when you go swimming, doesn't the absorption area just fill with water? And won't you come out with a sodden, heavily water logged undercarriage? And won't the blood end up washing out if the padded area into the pool much like when you actually wash them?
