How To Swim On Your Period – All You Need To Know

No, you won’t leave a blood trail in the water. Here’s how to handle beach season and your period this summer.

Whether you’re in swimming lessons, getting ready for sleepaway camp, or off on a vacation, or just headed to the beach, we’ve all had that intrusive thought: "Oh no… what if I get my period? Can I even swim on my period?"

From there, chaos ensues. We pack (dozens of) 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 too stressful and uncomfortable. Does any of this resonate?

At Kt, we created our new period swimwear collection so you can dip, dive, and swim comfortably – even on your period! Have some questions? No worries. Keep reading for some FAQs on swimming on your period in Kt!

What makes Kt swimwear different from period underwear?

We’ve spent years perfecting our period underwear, so we've got you when it comes to period swimsuits for teens. Period swimwear is just like the bathing suits you're used to  we offer bikinis and one-pieces in different coverage options  with the added advantage of absorbing your period blood. They are designed to perform in water and feel comfortable lounging by the pool. The only difference is a discreet gusset made of super absorbent material that can absorb three teaspoons of liquid, which is equal to three tampons or pads. Bonus: our swimsuits offer +50 UPF protection, which means the fabric helps harmful UV radiation from the sun.

But how does it work?

The layers in the gusset of the underwear work to trap and absorb your period blood 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 when you go swimming. 

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

The inner layers absorb the blood and trap it so there's no leakage. When it goes in the wash with detergent, it releases through the top layer — leaving it fresh and clean for tomorrow's swim. 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 swimming. 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 little leaks, leaving you to stay comfortable while you swim – even on your period.

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 going in and out of the water. Everyone’s period is different, and you know your flow best!

PS: If you really like them, you can wear these when you're not on your period, too! 

Where can I wear them?

Anywhere! In a lake, at the beach, in the pool, running through the sprinkler (heal that inner child), catching some rays in the backyard. Whether it’s a freshwater swim or a relaxing hot tub dip, they’re equally comfy (and leakproof!) both in the water and on land.

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 swim on your period in any body of water of your choice. So slap on some sunscreen, hop into your Kt Swim and let’s go swimming! 

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.
