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.

Great period swim bottom!

I purchased these for my 12 year old and she loves them. They work very well and you cannot tell they are anything other than “regular” swim bottoms. They fit great and stay put. I already purchased a second pair for her. My daughter is very picky about textures and fit and she says these are great and told her friends about them.

My daughter loves these, and not just when she is on her period! It's so hard to find bikini bottoms that don't show your cheeks, these have great full coverage!

Quite a mess

I bought these for my 15 year old daughter. We were on the beach less than an hour and had to leave because she sat down on a towel and bled through he swimsuit and onto the towel. She was so embarrassed. The bottoms are cute but definitely didn't save us from the period mishaps we were hoping for.
