Teen Sizing

Period? No problem. These bottoms let you swim with confidence, not discomfort. You can wear them alone or as backup protection to tampons and menstrual cups. Designed with three layers of 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 about the same as 1-3 regular tampons of period blood.

Layer 3: A waterproof outer layer prevents swelling.

Other Features:

- Classic bikini cut

- Bum coverage: Medium

- Super discreet liner

- 50+ UPF protection

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

Body: 85% Nylon / 15% Spandex

Knix swimwear
My teenage daughters love the knix swimwear. We have tried other brands and my girls always wore another bottom over the period ones. Knix made their swimwear look just like a normal bikini bottom and they love them. I also had to make an exchange and their process was so simple and easy. I highly recommend knix!
