MaxProof FlowLock
The leakproof underwear they can't copy.
Designed with thousands of real women. Rebuilt to pull leaks away faster, hold more, and help keep the vulnerable edges dry — without the bulk or noise.
It starts working the moment a leak happens.
Tiny perforations across the top layer help liquid pass rapidly into the absorbent core below. Once inside, the core distributes and locks it away.
Less time sitting on the surface. Less chance to travel toward the leg openings. A drier, more confident feeling.

Four layers. One purpose: keeping you dry.
RapidDraw™ perforated top
Pulls liquid away from the surface quickly.
Super-absorbent core
Captures and locks in more liquid.
Waterproof barrier
Helps prevent moisture from escaping.
Soft stretch outer
Thin, flexible, discreet and quiet under clothing.
No complicated system. No disposable pad required for everyday protection. Just put them on, wash them, and wear them again.
Built to help stop leaks from reaching the leg openings.
Increasing capacity wasn't enough. Absorption had to happen quickly enough to keep liquid from spreading sideways. RapidDraw™ pulls liquid down into the core while the expanded protective construction helps contain it inside the protected zone. Because "almost dry" isn't dry enough.
We didn't guess what women needed. We asked.
Dozens of surveys. Hundreds of conversations. Thousands of honest answers from women who actually live with bladder leaks. You told us:
- Make it absorb faster.
- Make it hold more.
- Keep the edges dry.
- Get rid of the noise.
- Keep it thin and comfortable.
- Make it affordable enough to wear every day.
So that is exactly what we built. A competitor can copy a photograph. They can't copy the women behind the product.
Made for real life — not just "just in case."
For the laugh that catches you by surprise. For long walks, travel days and hours away from home. For work, errands, exercise and everything you'd rather think about than bladder leaks. For women who want to rely less on disposable pads without sacrificing confidence.
Wear them 100 days. The risk is ours.
