Not sure where to start?
Choose by activity
For everyday wear, explore period pants. For nights, compare coverage and absorbency. For the pool or sea, choose purpose-made period swimwear.
Compare absorbency
Our teen collection includes medium-flow pants with up to 25ml absorbency and heavy-flow pants with up to 35ml per pair. Dedicated swimming styles offer up to 15ml.
Check the fit
Use the measurements for your chosen product rather than age alone. A comfortable, secure fit around the waist and legs matters.
First period? You do not have to work it all out at once.
Start with a comfortable pair, learn how often you need to change and build a routine that suits you.
For school or days out, pack spare pants and a wet bag. Knowing where you can change and having someone you feel comfortable asking for help can make getting started easier.
