AuntFlo™ Overnight Undies are your go-to for embracing comfort and confidence on your period nights! Holding up to 6 tampons, they provide leak-proof support without feeling super bulky.
They feel like regular underwear, but have a built-in period-proof lining to keep you comfortable and dry all night.
