Your contribution to the environment
By switching to period underwear, you can actively help the environment. Compared to disposable products like tampons or pads, this means:
🌍 You reduce your CO₂ emissions by up to 90%.
💧 9–10 liters of water are used to produce just one tampon. By using period underwear, you save over 11,830 liters of water in the long run.
🗑️ While around 49 billion disposable products are disposed of worldwide each year, by switching to period underwear, you avoid approximately 5.2 kg of waste in just 5 years.
⚡ In addition, you lower your energy consumption by around 390 MJ – which is equivalent to about 100 hours of vacuuming.
With period underwear, you not only protect the environment but also your body: my•mense models are 100% vegan, free of biocides, and made from environmentally friendly materials.

Antonia:
I think this period bikini from my•mense is just great because it looks like a normal bikini and also does its job. I never would have gone into the water on my period before, but now it’s no longer a problem for me.
Elisabeth from @elisabethlechner:
I’ve tried other period swimwear before, but you could usually see the protective layer or it was so thick that it was just uncomfortable. That’s something I noticed immediately with the my•mense bikini: the protective layer is barely visible and the fabric feels completely normal. I was able to move just as I always do – nothing bulky, nothing annoying. And it kept me leak-free, too – that really gives you peace of mind, especially when you want to go for a relaxing swim or just lounge by the water.
Izzi:
I wore the my•mense swimsuit when I went swimming on a light period day. It worked well; I didn't have to worry about anything. The swimsuit fit comfortably, nothing shifted, and I was able to move around normally. In terms of how it feels to wear, it’s barely any different from a regular swimsuit.
Lisi:
I was able to test the period bikini before the official launch – and was really pleasantly surprised. I wore it to the beach on a medium-flow day of my cycle and it was so relaxing! When my flow was lighter, I went swimming in the period bikini – and honestly, I was a bit nervous, but nothing leaked at all. The bikini fits perfectly, feels like regular swimwear, and looks just like it too – that was extremely important to me.
Ella from @holistic.health.coach:
I was able to test the bikini right by the lake at my parents' place – and I’m thrilled. It feels like a normal bikini, nobody noticed a thing, and it provides protection exactly where it's needed. I feel completely secure, I was positively surprised by the absorbency, and swimming in it is super relaxing.
Claudia from @callmeclautschi:
I was really curious to see how the period bikini would perform in everyday life—and I was pleasantly surprised. It fits comfortably, feels like normal swimwear, and most importantly: it’s leak-proof. Even after several hours at the beach, there were no nasty surprises. I didn't have to constantly check or worry. That's exactly how it should be.
Can you swim with it?
Yes, you can swim normally with my•mense period swimwear. For light to medium flow days, it's sufficient on its own.
For heavier days, you can simply combine it with a tampon or a cup.
Thanks to quick-drying, odor-free materials, you'll feel fresh all day long.
And don't worry: Nothing slips, nothing digs in – the fit is just as comfortable as regular swimwear, but with extra protection.
Care instructions
1. Wear & feel good

Panty tips
🩸 Rinse once before first use – this activates the absorbent layer and ensures full absorbency.
🩸 Use a mild detergent without fabric softener or bleach to keep the membrane absorbent and durable.
🩸 Use a laundry bag to further protect the material.
🩸 Store your panty in a small wet bag when on the go until you wash it at home.
🩸 With proper care, your my•mense period underwear will last around 2–3 years.

Read our frequently asked questions here
What is period swimwear?
Period swimwear looks like regular swimwear – but it can do much more. It contains a specially developed protective layer that reliably absorbs your period. This consists of several clever high-tech layers:
Absorbent layer: It safely absorbs and stores your period without feeling wet or uncomfortable.
Impermeable layer: This ensures that nothing leaks – not even when swimming or moving.
Breathable materials: For comfortable wear and reduced odor.
This way, you can go swimming completely relaxed during your period – without a tampon or cup. Period swimwear is reusable, sustainable, and ideal for light days in the water and medium days while relaxing or being active.
Can you swim with my•mense period swimwear?
Yes, you can swim normally with my•mense period swimwear. For light to moderate flow days, it's sufficient on its own.
For heavier days, you can simply combine it with a tampon or cup.
Thanks to quick-drying, odor-free materials, you'll feel fresh all day long.
And don't worry: Nothing slips, nothing digs in – the fit is just as comfortable as traditional swimwear, but with extra protection.
What happens if you go into the water with period swimwear?
Many believe that their period immediately leaks when swimming - but that's not the case.
Water pressure significantly slows down the flow.
As soon as you get out of the water, the absorbent function of period swimwear kicks in and safely catches the blood.
How much can the period swimwear absorb?
Period swimwear can hold up to 3 tampons worth of fluid.
