Leak-proof absorbency: 3 regular tampons= 1.5 regular pads= 4.5 pantyliners= 6 teaspoons= 25 mL This underwear features our unique leak-free technology in an extended crotch area with a medium absorbency - allowing confident coverage in front and behind. The machine-washable panty has a semi coverage fit on the hips and bum and sits under the belly button. The buttery-soft, stretchy, breathable and seamless fabric of these undies makes them ultra comfortable. They might feel snug at first but will relax with wash and wear.
