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.

These are great for my tween daughter! They go with the currents on top she has.
Love them! I wear them on top of my one pieces in the pool (swim teacher) so I don’t use the period bit really, but they’re awesome!
I'm and adult, so went up a size to fit the shorts. Very comfortable and feel like workout shorts. Nice quality as usual.
My autistic daughter struggles with understanding her period and all Knix products are a godsend, but these shorts are amazing! She loves them and they help us manage her periods without any incidents. Highly recommend!!!
