Yes, on light to medium days.
This pair holds up to the capacity shown above. That covers most light and medium days in the water. On your heaviest days we recommend pairing it with a cup or tampon, so you can swim without thinking about it.
Not when the fit is right.
The leak-proof layer and the snug leg openings keep everything in, even when you move. Water pressure doesn’t push fluid out. The fit does the work, so choose your size carefully (see the size chart).
A swim session, not a full day.
Plan it like a beach or pool visit: a few hours of swimming and lounging. After that, change into dry period underwear. Swimwear is made to dry off quickly, not to stay damp all day.
Yes. No bulk, nothing shows.
The absorbent layer is thin and sits in the lining. From the outside it looks and feels like a regular bikini bottom or swimsuit. Not see-through, even when wet.
Yes, just rinse it after.
The fabric is made for pool and sea. Rinse it in cold fresh water right after swimming. That keeps the colour and the absorbent layer working for longer.
Free exchange within 30 days.
Try them on at your own pace. If the fit isn't right, we'll exchange your size for free — no questions asked.

Customer stories
"Ideal for long flights and train rides"
Got through an entire flight without worrying about where I'd change.
Great for gym days
Wore it during gym class and nobody noticed a thing. Exactly what I was looking for.
With three kids' schedules I never know when I'll get a bathroom break. This buys me the extra hours.
My cycle's been unpredictable for two years, this gives me peace of mind
I never know anymore when it's coming or how heavy. With this underwear I don't have to guess what I'll need in advance.
On the days I only have spotting, I genuinely forget I'm wearing it.
"Handy at festivals"
No more bathroom lines to change something. Wash at the end of the day, ready for the next.
"Works even on irregular heavy days"
Nice not having to gamble between light and regular during this phase of life.
Sized for an actual body
So many period underwear brands stop at a size that doesn't fit me. The cut here actually sits right instead of digging in at the waist.
Did the math against what I used to spend monthly on disposables — this pays back fast if you actually rewear it for a couple years.
