Our period swim bottoms contain a triple-layer gusset that absorbs your flow and locks in leaks, whether you're in or out of the water. When they go in the wash with detergent, the blood releases through the top layer—leaving your swimwear fresh and clean for next time. Yes, your other clothes will remain stain-free!

Here's the breakdown of our 3-layer leakproof technology:

Layer 1: A silky-smooth top layer that sits comfortably against the skin.

Layer 2: A highly-absorbent middle layer designed with our leakproof technology to absorb up to 1-3 tampons worth of period blood.

Layer 3: A waterproof outer layer prevents swelling. 

Not always. When your flow is light, our swimwear can be worn alone without any additional period protection. On super heavy days, we recommend wearing a tampon or menstrual cup with your swimwear. Every period is different though, and we recommend doing whatever makes you feel most confident.

Machine wash cold and lay flat to dry. Do not bleach, iron, or dry clean.

Check out our size chart here.

Absolutely! The leakproof liner built into all of our period swimwear is undetectable, so they look and feel just like regular swimwear.

Our styles are made to fit teen bodies. For period swimwear in adult sizes, please visit Knix.

Total lifesaver!

I bought these on a whim, not even knowing if my daughter would ever end up using them. Well, a couple weeks later, her period came the exact day we were going to go swimming so having them ended up working out perfectly. She had no leaks and could play comfortably all afternoon!

She’s 11, tall and slim and I usually buy her an XS in the underwear but since she’s right at the cusp of sizing up, I went for a Small so it should fit her next year too.

Opportunity to swim!

These have given my 11 year old daughter the opportunity to swim any day of the year. Last year she avoided swimming when she was on her period. Fit small. Comfortable.
