The most absorbent period underwear
ooia Slip Seamless Ultimate: The most absorbent period panties available
We were the first to bring period underwear to the German market. Now we're revolutionizing it – again!
What makes the ooia Ultimate Period Slip so special?
It's simple: it combines everything you love about ooia and is also the strongest period panty ever. Thanks to our new Magic Membrane Pro Technology, it absorbs up to 10 tampons worth of liquid while being only 1 mm thicker than normal underwear.
This means:
- Unprecedented absorbency - leak-proof even with very heavy periods
- Like all ooias, soft, breathable and comfortable on the skin - without restricting you
- A brand new innovation - developed for you and your cycle
How was the ooia Ultimate Menstrual Slip developed?
The journey to the Ultimate Period Slip was anything but a sprint. It was a marathon full of dedication, precision, and innovation.
For three years, our experts fine-tuned the new Magic Membrane Pro Technology and the entire design until every detail met our high standards. Our goal: a slip that offers maximum protection, feels like your regular underwear, and can give menstruators even more freedom.
During this time, the membrane was tested, optimized, and re-examined countless times. The style went through countless revisions, always with the aim of becoming even better, even safer, and even more comfortable.
Every Ultimate Period Slip is a product of passion and precision - developed to make life easier for menstruators. And because we are convinced: innovation takes time, courage, and the confidence to always strive for the best possible.
How does period underwear feel?
Almost like nothing. And at the same time, like everything you need.
Our SlimTech innovation ensures that the underwear is even thinner than comparable models and yet stronger than ever.
It was important to us that you truly feel comfortable in your own skin and in your period underwear.
No rustling, no sweating, no foreign body sensation, just a natural wearing experience that accompanies you through your day and night.
How Does Magic Membrane Pro Technology Work?
We've reengineered our new membrane from the ground up to combine maximum performance with minimal material usage.
The Technology:
- New, even more absorbent layers that can hold up to 50 ml of liquid.
- An even thinner membrane system with improved performance.
- A layer system you'll barely feel - only minimally thicker than normal underwear.
- Easy to use: Like all ooias, the panties can be machine washed at up to 40 degrees and then simply air-dried.
With this, we are creating a whole new generation of period underwear.
Reengineered. For your cycle.
Is the Ultimate Period Panty the right choice for a heavy flow?
Yes! It's for anyone who wants absolute security – no matter how heavy their period is.
The Ultimate is ideal:
- On particularly heavy flow days,
- At night,
- During the postpartum period,
- or simply when you want to feel completely secure.
The integrated membrane extends almost to the waistband at the back, providing complete leak protection – especially at night when you're lying down, or when you're moving a lot.
