This is no bueno. Teen girls are our most powerful resource: they are our future politicians, scientists, artists, and dreamers. And there are so many more important things they could be thinking of than the possibility of period leaks. It's one of the reasons we created Knixteen: because the teen years are stressful enough. And as we head back to school, we wanted to send a gentle reminder that if there's a teen in your life who could use a little peace of mind, Knixteen's leakproof period underwear are here for her.
