Who is this for?
Everyday underwear designed for comfort, confidence and a smooth finish under clothing. A no-show brief for everyday wear, with built-in protection for light leaks whenever you need it.
How the leakproof liner works
- Stays dry against your skin: a moisture-wicking inner layer pulls fluid away from your body so you do not feel damp.
- Locks it away: a soft cotton layer absorbs fluid and holds it in place.
- Stays protected: a built-in waterproof layer acts as the final barrier to help keep light leaks off your clothes.
Designed for light leaks. Not intended for heavy flow.
