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 about the same as 2-3 super tampons worth of period blood.
Layer 3: A waterproof outer layer prevents swelling.

- Mesh interior lining
- Super discreet liner
- 50+ UPF protection

My daughter feels so comfortable in these and true to size. She's happy that she can enjoy pool days!

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.

My 13 year old feels very comfortable in this non-cheeky, cute swim short and was beyond thrilled that it totally worked in swim class during her period. She really feels like she dodged that tampon bullet. LOL
This style fits as expected.
Also, I am really happy with the customer support team of knix. They really helped me find the right style of period swim wear for my kid.
