Teen Sizing
Our most-requested swim style ever! Perfect for teens who want fuller coverage in the front and back—while being fully protected on their period. Wear it alone on light days, or with a tampon or menstrual cup on heavy days.
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.
Other Features:
- Bum coverage: Max
- Wide waistband for comfort
- Mesh interior lining
- Super discreet liner
- 50+ UPF protection

My girl is small so it’s hard to find period anything that fits. This fits her perfectly and provides great coverage. It is not bulky at all either. Will buy more.
