TEEN PERIOD SWIMWEAR
Leak-free, stylish, perfect fit teen period swimwear for active young girls and tweens to enjoy the pool or the beach without stress every day of the month!

Why choose teen period swimwear?
Did you know that 67% of girls either ditch sessions or quit swimming because of their period? That's a staggering number. By choosing the right swimwear, you’re telling her that her period shouldn’t dictate her activities.
Pads in the pool? They're not the best mix—becoming soggy and moving out of place, which is the last thing anyone wants. Our teen period swimwear collection is the antithesis of this scenario—offering leak-proof confidence with pool-ready, period-proof innovation.
UnderSwim OG: Period Swim Underwear (Regular)
























Can girls still swim when they have their period?
Yes, Here's How!
"But how will I go swimming!?" It's one of the most commonly asked questions when a girl gets her period.
She can hit the pool, enjoy the beach with friends, or dive into the ocean waves even while on her menstrual cycle without:
- Using tampons (which often freak girls out until they're a little older)
- Resorting to the awkwardness of a pad in the pool, or
- Being relegated to the sidelines.
Our collection of teen period swimwear is designed with tween and teen swimmers in mind, ensuring she can master her metres any day of the month.
UnderSwim G-Fit: Period Swim Underwear (Thong)












Invisible Period Swim Undies for Girls
Featuring four layers of super absorbent, paper thin protection.
Hide under full bottom swimwear for leak-proof confidence in the pool or at the beach. All she needs is sunscreen and she's protected against everything summer could throw at her!
Layers of super-absorbent, whisper-thin protection
Crafted from OEKO-TEX® Standard 100 certified fabric, our period swimwear tested to ensure she's not exposed to any harsh chemicals.
With layers of super-absorbent, whisper-thin protection right where it's needed, there's no bulky, soggy aftermath to contend with. No need to worry people might be able to tell if you're wearing period swimwear!
Our distraction-free designs deliver an inch-perfect fit, stay put straps and supreme freedom in the water. Whether she's got light, moderate, or heavy flow, we got you covered. Our teen period swimwear products absorb 2-3 tampons worth of blood providing a leak-free and fun day in and out of water. You can also pair them with a tampon or menstrual cup for extra protection from leaks.
What's the difference between absorbent swim liners and period pads?
Diving into the pool with teen period swimwear is such a game changer compared to using pads. Why? Well, imagine chilling in the pool without the worry of that weird, soggy pad feeling or fear of leaks.
Period swimwear is made with layers of absorbent lining that are made for protection in the cool. The fabrics are super smart - they're absorbent where you need it, and water repellent everywhere else, so you won't feel like you're lugging around a wet towel while you do your best mermaid impression.
Plus, water can also make the sticky backing that keeps your pad in place ineffective. Another reason why it's not good idea to swim on your period with a pad. Enjoy swimming in style with our life-changing period bikini bottoms and one-piece swimsuit options for teens and tweens.

Care Instructions for Girls Period Swimwear
- Make sure you rinse your period swimwear to get rid of chlorine or salt water. It protects the water resistant sealant and keeps your swimwear looking and performing like new.
- Machine or hand wash in cold water.
- Avoid fabric softener, the tech layers in the period liners aren't a fan.
- Lay flat to dry or hang out, no tumble drying. It messes with the lining.
- Do not bleach, iron, or dry clean. Keep care simple and natural and your swimwear will love you for it!
