Feels like normal underwear. No pads, no liners, no "am I wearing a nappy?" feeling.
Nobody will know. Just 1.5 mm thin, so there are no lines or bulk, even under your tightest leggings.
Stop planning around leaks. Sneeze, laugh, run, lift, and forget you're wearing them.
Stay dry and fresh. Moisture is pulled away from your skin, with odour-control built in.
Protects more than your undies. Leggings, jeans, the car seat, your sheets.
No more "just in case" liners. Wash, wear again, and stop rebuying every month.

CoreFlow Technology is built into the gusset in three thin layers:

Pull: a soft top layer draws moisture away from your skin.

Trap: an absorbent core locks it in (up to 4 pads' worth) and helps reduce odour.

Seal: a waterproof barrier stops it from reaching your clothes.

All of it in about 1.5 mm.

One pair. Made for the moments your bladder has other plans.

The sneeze, the squat, the run, the middle of the night. Light bladder leaks, handled by underwear that looks and feels completely normal.

🛌 Sleep Through the Night

No towel on the bed, no 3am sheet checks. Protection that stays put while you sleep.

🤧 Sneeze. Laugh. Jump.

The cough at your desk, the belly laugh at dinner, the box jumps at the gym. Handled quietly.

🏃‍♀️ Move Without Holding Back

Running, jumping, lifting, Pilates. Stop choosing workouts around your bladder and just train.

🐣 Back After Baby

Pram walks, your first class back, your first run. Protection while your body rebuilds.

Underwear designed to keep you dry all day.

Put them on

Just like your normal undies. Pick your usual size, no pads, no liners, nothing to stick in.

Live your day

Work, school, run, gym, dinner out. Sneeze, laugh, move, and forget you're wearing them.

Wash & wear again

Machine wash up to 60°C, hang to dry, and they're ready for next time.

So… where does the leak actually go?

Three thin layers inside the gusset. Each one has a single job.

Pull it away. The soft top layer draws moisture away from your skin the moment it happens. So you're not sitting in it.

Trap it. The absorbent core locks it in, up to 4 pads' worth, with an antibacterial treatment. That helps keep odour down.

Seal it off. A waterproof barrier underneath stops it from reaching your leggings, your jeans, the car seat, or your sheets.

I honestly forgot I was wearing leakproof underwear. They feel soft, don’t feel bulky at all, and I felt completely secure all day.”

Helen R.

Brisbane, QLD

I bought them for the occasional bladder leaks and they’ve made such a difference. No more constantly worrying when I’m out of the house

Amanda T.

Sydney, NSW

I was worried they would feel thick or uncomfortable, but they actually feel like normal underwear. Very comfortable and surprisingly breathable.

Julie P.

Perth, WA

After having kids, little leaks became something I just accepted. These give me so much more confidence when I’m walking, exercising or laughing

Claire W.

I’ve tried a few different brands and these are easily the most comfortable. The fit is flattering and they stay in place without digging in

Michelle D.

I use them mainly overnight and I sleep much better knowing I’m protected. They wash really well too and still feel soft after multiple washes.
