product details

Period x Beach: The highly anticipated ooia beachwear is here! We present the ooia Beach One Piece in a clean, minimalistic design with a low back neckline as well as adjustable straps. Enjoy a relaxed day at the beach, pool or playing beach volleyball.

The ooia Beach One Piece is made of a slightly thicker swimsuit fabric - just as you know it from your usual bathing suit.

The ooia Beach One Piece is adjustable to your individual strap length by the lacing at the back. In addition, the ooia Beach One Piece contains removable pads in the cups.

Vegan and fair: so that your ooia Beach One piece can accompany you at the beach and sand and sunscreen do not harm it, the crotch layer of the ooia Beach One Piece is made of synthetic fibers instead of merino wool. This makes the ooia Beach One Piece vegan.

Note: To keep your ooia Beach One Piece leak-proof, we recommend not wearing it for swimming, as the ooia will soak up water and not absorb other fluids like blood.

The ooia Beach One Piece holds up to three tampons of liquid while feeling completely dry. This makes it ideal for your medium to heavy menstrual period days. Plus, the ooia Beach One Piece is washable, making them reusable. You can wear the ooia Briefs alone or as a back-up to other period products.

ooias are produced ethically and ecologically fair in Portugal, Lithuania and Croatia with fabrics from Europe.

Our models Toni and Caroline wear a size 36 and our model Mikaela wears a size 42.

With your purchase you support organizations that promote female empowerment with their projects - here you can find out more.


The ooia Beach Collection is as beautiful and comfortable as your favorite beachwear, but it can do so much more: it has an integrated membrane system in the crotch that soaks up liquid and prevents it from leaking. 

  1. The layer closest to the body is made out of synthetic fibres that are insensitive to sunscreen and sand. It quickly wicks moisture away from the body. So you feel dry at all times. In addition, it is equipped with a bacteria-inhibiting agent, so that  no bacteria can multiply and no unpleasant odor develops. More info: click here
  2. The middle layer consists of specialized fibers that absorb moisture very quickly. This layer is also equipped with an anti-bacterial agent. More info: click here.
  3. The outermost layer is a liquid-impermeable membrane that doesn't let any liquid through to the outside, protecting you from leaks. In addition, this layer - just like all the other layers - is breathable and thus ensures that you do not sweat.


Wash your ooia once before the first use.

After wearing your ooia, it is best to wash it by hand in cold water.

Then you can put it into a laundry net and into the washing machine and wash it at 40 degrees ideally in the easy-care wash cycle - you can also do this along with other dark laundry using color detergent.

Please do not use bleach or fabric softener, as this will limit the effectiveness of ooia.

Please also do not dry clean - but who takes their underpants to the dry cleaners?

Ironing is also a no-go, just hang ooia on the clothesline and it will soon be ready for use again.

We recommend removing the optional pads before washing and washing them separately by hand.

If you treat ooia well, it will keep it's full bacteria-inhibiting effectiveness for about 2 years. After that, of course, you can still continue to use them as "normal" underpants.

bacterial inhibition

Because your health is our top priority, we've sought the opinion of gynecologists on the requirements for bacterial growth inhibition. 

These gynecologists confirm that it is fundamentally important that period underwear inhibits bacteria growth - and that high-quality, tested fabrics are used for this purpose.

Our membrane system has bacteria-inhibiting properties at the crucial points -so that neither bacteria can multiply nor develop unpleasant odors. Of course, we do not use any nanoparticles that are controversial in terms of health.

The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.


ooia is made of carefully selected, specialized fabrics made in Europe. The materials of our suppliers are certified and tested for harmful substances according to STANDARD 100 by OEKO-TEX® [21.0.46579 HOHENSTEIN HTTI]. Thus, the ooia Beach One Piece is certified skin-friendly and harmless to health.

Some raw materials which enter our fabrics cannot be sourced from Europe, as this is not possible for climatic reasons.

material composition:

Upper fabric: 82% polyamide, 18% spandex

Lining: 84% polyamide, 16% spandex

Lining Crotch: 80% polyamide, 20% spandex

Mid-layer: 80% cotton, 20% polyester

bacteria inhibition

Your health is our top priority

Gynecologists confirmed us that a bacteria-inhibiting coating on period underwear is indispensable.

This prevents odors and the multiplication of pathogens.

Silver has been used for centuries to protect against disease. Already in ancient Greece and Rome it was used to disinfect water.

The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.

It is very important to us that we communicate transparently in this regard. 

Nano particles are not used.
