1/3 of teens experience irregular periods.

When you get your first period, your body is going through some major hormonal shifts. This means that periods can sometimes come more than once per month or skip months in between. That’s when Kt comes in handy. Wear them for every period—even for just-in-case!

Worried about leaking? Kt Period Undies can hold up to 9 super tampons.

Depending on absorbency, pads and tampons need to be changed every few hours. But Kt Period Undies can hold up to 9 super tampons’ worth without the discomfort or bulk. Plus, there’s no pad lines. Bonus for teens who might be anxious about visibility.
