1 in 2 teens skip sports because of their period

Too many teens sit out because of their period. We want to empower them to stay active and confident, in and out of the water. Our Period Swim is designed so they can show up to play, even on days when their period shows up too.

Kt Period Swim can hold up to 3 super tampons worth

Worried about leaking? Kt has your teen’s back with triple layer protection, including a built-in absorbent liner and a thin membrane designed to act as a barrier for blood and water. All so they can swim worry-free.

Green floral underwear equals three tampons, with text 'Holds up to 3 super tampons'.

A World of Possibility

Is your teen not ready for tampons? Do they dread changing them in a freezing cold change room or public restroom? We don’t blame them. Luckily, Period Swim couldn’t be easier to use. The thin, discreet liner keeps them protected in and out of the water.
