Learn How Kt's Period Swimwear Collection Keeps You Dry from the Pool to the Beach

It's time to dive into our new Period-Proof Swim for teens!

Whether you’re in swimming lessons, getting ready for camp, or off on a vacation, we’ve all had the thought: "Oh no… what if I get my period?"

From there, annoyance ensues. We pack extra tampons, we throw on a pair of swim trunks, and despite the gorgeous weather and hot sun, we suspiciously tell everyone, “I just don’t feel like swimming today." The thought of leaking in the water or on a beach towel is simply stressful and uncomfortable. That’s why we created our new Period Swimwear Collection — so you can dip, dive, and swim comfortably even on your period!

How does Kt Period Swimwear work? What makes it different from Period Underwear? 

We’ve spent years perfecting our Period Underwear, so we got you when it comes to Period Swimsuits for teens. Kt Swim has a super discreet absorbent pad in the liner that absorbs up to 3 tsps of liquid, which equals 3 tampons or pads.

But how does it work? Let’s get science-y! The layers in the gusset of the underwear work to trap and absorb your period so it doesn’t leak in the water (or on land!). It features the same absorbent technology as our underwear, but it has an extra thin layer of waterproof material for extra protection. 

How do they lock in your period but still get clean in the washing machine?

The inner layers absorb the blood and traps it so there's no leakage. When it goes in the wash with detergent, it releases through the top layer — leaving your swim fresh and clean for tomorrow's laps. Reminder: no bleach or softener, and lay flat to dry. 


But I thought I didn’t leak in the water!

Although it may seem like it, your period doesn’t really stop while you’re in the water. Instead, you might be experiencing a reduction of flow due to the water pressure. Your period is still happening, it’s just not flowing out of your body at the same rate. Kt’s Period Swimwear traps these leaks, leaving you to swim laps around everyone. 


When should I wear them? 

If your flow is light, or you’re at the end of your period — you can wear these completely solo. If your flow is heavy but you’re planning to hit the water, you can still wear a tampon or menstrual cup while swimming if that's what you're comfortable with. Our Period Swimwear will catch any leaks that might sneak in, especially if you’re in and out of the water. Everyone’s period is different, and you know your flow best!

PS: You can wear these when you're not on your period, too! (They're that cute.)

Where can I wear them? 

Where? Anywhere! In a lake, at the beach, in the pool, running through the sprinkler, catching some rays in the backyard. Whether it’s a camping trip or a relaxing hot tub dip, they’re equally comfy (and leakproof!) in and out of the water.

Are they easy to care for? 

Yes! And it couldn’t be easier. Not only is the fabric in Kt swim chlorine and seawater resistant, but they also have 50+ UPF protection. That means you’re good to go in any body of water of your choice. So throw on some sunscreen, hop into your Kt swim and say “not today rays!”

How do I find my right size? 

You can find sizing charts on every product page, but if you’re not sure or need help double checking you can book a free virtual fit appointment with one of our fit experts! They’ll make sure you get the right size so you can just keep swimming.
