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.

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

Purchased these and another style for my teen who was going to get her period during our vacation. Not feeling comfortable with using tampons I went on the hunt for period friendly options. These were a lifesaver for her. She didn't worry about any leaking while swimming. They worked great. I went ahead and ordered her the size according to some other reviews and they fit great. Highly recommend!
Bought for me teen daughter. Went up one size as suggested by reading the reviews. My daughter said it fits perfectly & it was cute (and she's picky). It held up to a day spent swimming & cliff jumping into the water without any leaks.
My daughter only just began her adventures of having her period. What I’ve always said to her is that I don’t want her period to interrupt her life in any way. I want her to feel uninhibited regardless of her cycle. So, it makes my heart happy knowing that this products aligns itself with my message to my daughter.
