Our technology
How does it work?
Two years of work with a textile engineer went into creating underwear that absorbs menstrual blood for up to 12 hours, without any damp feeling, odor, or visibility under clothing. Here’s what’s inside and why it works.
12 h
of protection, equivalent to 2 to 6 tampons depending on the model

Step 01
Three materials, each with its own role
In the absorbent area, three technical materials are layered, from the skin outward. Hover over the diagram or cards to identify them.
Skin side
Clothing side
Moisture-wicking fabric
Against the skin. It wicks the flow toward the absorbent material and dries immediately, unlike a pad, which stays damp.
What it changesNo feeling of dampness
CompositionHydrophilamide, polyamide, elastane
The absorbent material
It holds back flow all day or all night, for up to 12 hours. Antibacterial, it prevents odors from developing.
What it changesUp to 12 hours, zero odor
CompositionPolyester
The waterproof and breathable membrane
Finally, it blocks leaks while allowing the water contained in the blood to evaporate thanks to body heat. No moisture buildup.
What it changesZero leaks, without a stuffy feeling
CompositionPolyester, polyurethane
The main material
It’s the underwear itself: soft and designed to move with you. Skin-like microfiber or organic cotton, depending on the range.
What it changesComfort and invisibility
CompositionPolyamide and elastane, or GOTS-certified cotton
Only the gusset area is made up of several layers. The rest of the briefs is not lined, which makes them twice as thin as other period underwear.
Close-up view
The materials, an absorption test, and the seamless finish, filmed up close.
The three materials
Wicking, absorbent, waterproof: the three layers of the absorbent zone.
The absorption test
The liquid is drained away and then absorbed: the surface stays dry to the touch.
The seamless finish
Clean edges, no ridges: invisible under clothing.

Step 02
Seamless, our signature style
Our panties are not sewn: the materials are heat-bonded. A technical choice that serves three purposes.
This is also why the panties should be washed at a maximum of 30°C: the heat-bonded seams are sensitive to heat.

A day with
What happens between the moment you put it on and the moment you rinse it.
Put it on
Like regular underwear. The absorbent area should fit snugly: it follows your movements and prevents leaks.
The flow is drained, then absorbed
The moisture-wicking fabric dries instantly, the absorbent fabric holds, and the membrane blocks. No moisture, no odor, nothing shows.
Day or night, without even thinking about it
Equivalent to 2 tampons for a medium flow, 4 for a heavy flow, 6 for Hécate. During sports, at the office, or at night: it stays in place.
Rinse with cold water
Until the water runs clear, then machine-wash at 30 °C with the rest of the laundry. It air-dries and is ready to go again.
Good to know
The panties can be worn alone or in addition to a cup or tampon. Never with a pad or panty liner: their adhesive makes the absorbent area useless. A fast, frequent flow may saturate them sooner than expected; in that case, change your panties or choose a more absorbent model.

Our commitmentsAnd to make it last
Four gestures, two to three years
The fabrics themselves absorb and limit bacteria: their effectiveness does not expire. Properly cared for and alternated with others, a pair of period underwear will last you two to three years.
Your questions
Do I feel damp?
No. The material in contact with the skin wicks the flow toward the absorbent material and dries immediately. That’s the difference compared with a pad, which keeps the liquid on the surface.
What about odors?
The absorbent material is antibacterial: it prevents the bacteria responsible for odors from developing. And because the membrane is breathable, the water contained in the blood evaporates instead of causing dampness.
How long can I keep it?
Up to 12 hours in microfiber, 8 hours in cotton, depending on your flow. On heavy-flow days, change your underwear during the day or choose a more absorbent style: our guide will help you choose.
Can I wear it with a pad or panty liner?
No: glue would make the absorbent area useless. However, you can wear it alongside a cup or tampon on very heavy-flow days.
Why wash it at a maximum of 30°C?
Because our panties are heat-bonded, not sewn. The heat from a tumble dryer, radiator, or hot wash could damage the bonded seams. Rinse in cold water, machine wash at 30°C in a mesh bag, and air-dry: that’s all. Care guide.
How long does a pair of panties last?
It is the materials themselves that absorb and limit bacteria: their effectiveness does not expire. Like any underwear, it wears out over time. With proper care and rotation with others, it should last two to three years.
Where are they made?
Designed in Paris, our panties are made in Tunisia, in a factory renowned for its lingerie expertise and regularly audited for working conditions. The materials come from France and Italy.
